Book review: Rethinking Enterprise Storage – A Hybrid Cloud Model by Marc Farley

The O’Reilly @oreillymedia media folks (oops, excuse me, Microsoft Press) sent me out (that’s a disclosure btw) an real soft cover print copy of Rethinking Enterprise Storage – A Hybrid Cloud Model by Marc Farley aka @MicroFarley of Microsoft/Storsimple that features a forward by Martin Glassborow aka @Storagebod.

Rethinking Enterprise Storage - A Hybrid Cloud Model

Topics and themes covered in the book

  • Understanding scale storage architectures (hmm, great way of saying hybrid ;)
  • Rethinking data protection including disaster recovery (DR) best practices
  • Enhancing data protection using cloud snapshots beyond traditional backups
  • Deterministic thin recovery capabilities while dynamically expanding capacity to the cloud
  • Implement data footprint reduction (DFR) including archiving digital documents to the cloud
  • Insight and awareness into keep performance indicators along with various use cases

Rethinking Enterprise Storage book Details

Paper back
Features: Many diagrams, figures, index, glossary
Pages: 101
ISBN: 978-0-7356-7990-3

One of the many books many figures on the right, on the left i needed to hold a page down ;)!

What’s inside the book

Make no mistake that this is a Microsoft and Storsimple themed book, however IMHO Marc (aka Farley) does a great job of making it more relevant than just another vendor product book (JAVPB). While it is a Microsoft focused book around enabling hybrid cloud storage for various applications, the premises presented could be adapted for other environments or implementations. The book at 101 pages including table of contents (TOC), index, appendix, glossary and other front matter is a very easy and fast read while providing more information or coverage than what might be found in a "Dummies" type themed book.

Looking inside Rethinking Enterprise Storage by Marc Farley
Start thinking outside the box (or cloud), imagine what you can do with a Hybrid cloud!

Summary

Overall I found the book to be good and not just because I know Marc or that the O’Reilly folks sent me a free copy (I had actually previously received the electronic ebook version), rather that it is timely and does a nice job of conveying the topic theme and setting up the conversation, time to rethink storage for enterprise and other environments. IMHO the question is not if hybrid cloud storage is in your future, rather when, where, why, for what, how, with whom and related conversations. While you can buy a copy of the book at various venues, it shouldn’t take a lot of effort to get your own printed soft cover copy, or an ebook version.

Btw, here’s a pod cast discussion with Marc Farley from spring 2013 at SNW, as well as a link to a hybrid cloud and object storage post he did over at Microsoft Technet.

To summarize and quote Marc Farley "Hey now…."

Ok, nuff said

Some Windows Server Storage I/O related commands

Storage I/O trends

Some Windows Server Storage I/O related commands

The following are some commands and tools for Microsoft Windows environments that are useful for storage I/O activities (among others).

Microsoft Windows

Finding a Windows physical disk, SSD or storage system device name

So you may know and how to find out the more familiar Windows storage device (Solid State Device – SSD, Hard Disk Drives – HDD among others) names such as A:, B:, C:, D: as what you can view from the Windows Explorer, Computer or Admin tools.

Windows storage devices

However what if you need to find out a physical name for raw (not mounted) and mounted devices for configuration? For example, if you have a tool that wants the physical name for your C: drive that might be \\.\PhysicalDrive0\?

No worries, use the command WMIC DISKDRIVE LIST BRIEF

WIndows physical device name

Need more detail about the devices beyond what is shown above?

Then use WMIC DISKDRIVE LIST or as in the above example, direct the output to a file with the results shown below (scroll to the left or right to see more detail information).

Remembering (or learning) Xcopy

Some of you might be familiar with Xcopy and if not, it is a handy tool for copying files, folders and directories to local as well as networked storage. Some handy Xcopy command switches include:

/j = use un-buffered IO for large files
/y = suppress prompting
/c = continue if error
/E = copy sub directories
/H = copy hidden files
/Q = quiet mode (don’t list files being copied)

In the following example the content of the Videos folder and its sub-directories (83.5GB) are copied to another destination. Note the Time /T command that is also shown which is useful for timing how long the copy takes (e.g. subtract start-time from end-time and you have elapsed time). In this example 83.5GB are copied from one place to another on the same SSD device and using the results of the Time /T command the elapsed time was about 12 minutes.

Windows SSD TRIM
Xcopy command example

Diskpart, don’t be scared, however be careful

Ever have a Windows storage device or system that failed to boot, or a problem with a partition, volume or other issue?

How about running into a situation where you are not able to format a device that you know and can confirm is ok to erase, yet you get a message that the volume is write protected or read only?

Diskpart is handy, powerful and potentially dangerous tool if you are not careful as you could mistakenly drop a good volume or partition (e.g. the importance of having good backups). However Diskpart can be used to help repair storage devices that have boot problems, or for clearing read only attributes among other tasks. If you are prefer GUI interfaces, many of the Diskpart functions can also be done via Disk Management interface (e.g. Control Panel -> All Control Panel Items -> Administrative Tools -> Computer Management -> Storage -> Disk Management ). Note that Diskpart to do certain functions will need to be run as Administrator.

windows diskpart

In the above example the LIST DISK command shows what disks are present (on-line or off-line) which means that you may see devices here that do not show up elsewhere. Also shown is selecting a disk and then listing partitions, selecting a partition and showing attributes. The Attribute command can be used for clearing Read Only modes should a partition become write protected.

Hint, ever have a device that was once had VMware installed on it, then you move it to Windows and try to reformat for use and get a Read Only error? If so, you will want to have a look at Diskpart and the Attribute commands. However BE CAREFULL and pay attention which disk, partition and volumes you are working with as you can easily cause a problem that would result in testing how good your backups are.

Is SATA SSD TRIM Enabled?

If you have a SATA SSD the TRIM command is a form of garbage collection that is supported with Windows 7 (SAS drives use the SCSI UNMAP). Not sure if your system has TRIM enabled? Try the following command as administrator. Note that if you see a result of "0" then TRIM is enabled while a value of "1" means that it is disabled for your system.

Windows SSD TRIM

Want to learn more about TRIM, check out this piece from Intel as well as this Microsoft Windows item.

Having issues with collecting CPU and performance statistics?

Have an issue or problem collecting your system statistics, or when running a benchmark, workload generation tool such as vdbench and getting an "Unable to obtain CPU statistics"?

Try the Lodctr /R command (as administrator), however read this Microsoft Tip first to learn more.

Windows Lodctr /R

Sdelete and drive erase

Like its name implies, if you do not have this tool, you can download it here from Microsoft to not only delete files, folders, as well as write "0" patterns across a disk to secure erase it. You can specify the number of times you want to run the write "0" patterns across a disk to meet your erasure requirements.

There is also another use for Sdelete which is if you need or want to pre-condition a SSD or other device such as for testing, you can run a pre-conditioning pass using Sdelete.

Some command options include -p #n where "n" is the number of times to run, -s recursive to process sub-directories, -z to write "0" or zero out the space on the device, -c for clean, -a to process read-only attributes. Learn more and get your copy of Sdelete from Microsoft here.

Rufus, Seatools, Samsung Disk Magician and Cyberduck

A handy tool available from Seagate (may only work with Seagate and their partner devices) is SeaTools that can give drive information, health and status as well as perform various tests including SMART.

Seagate Seatools
Seagate Seatools example

Different HDD and SSD as well as storage system vendors give tools for configuration, monitoring, management and in some cases data movement with their solutions. Samsung SSD Magician is a tool I have installed for managing my SSDs (830 and 840 Pros) that has features for updating firmware, drive health as well as performance optimization. Other hand tools include the Samsung copy tool based on Clonix as Acronis among other clone or data migration utilities (more on those in a future post).

While the Microsoft WIndows USB Tool is handy for dealing with Microsoft ISO, however for creating USB’s with ISO’s such as for installing VMware or Linux on bare metal systems, Rufus is a handy tool to have in the tool-box.

Rufus ISO to USB tool

Another useful tool that functions as an SSH and FTP utility is Cyberduck that also supports access to Amazon S3 among other cloud services.

There are many other tools for server, storage I/O and other activities on WIndows, not to mention other platforms, however hopefully you find the above useful.

How about it, what’s your favorite Windows server, storage I/O tools and commands?

Ok, nuff said (for now)

IoD, IoT, IoE, IoS, IoP, IoU and IoX are in your future

Storage I/O trends

IoD, IoT, IoE, IoS, IoP, IoU and IoX are in your future

Have you figured out the new buzzword trend for 2014 that starting ramping up in 2013?

Yup, its Internet of Things (IoT) and Internet of Devices’s (IoD)

Assuming that IoT, IoD and other variations catch on which looks like they will, this could bring relief and rest for the over-worked Big Data and Software Defined "X" buzzword bingo bandwagon usage.

Buzzword bingo

Introducing IoX?

For those not familiar with Software Defined "X", simply replace "X" with your favorite term such as Data Center (SDDC), Networking (SDN), Storage (SDS), Marketing, (SDM) among others.as the new IT (and beyond) industry term might just take some pressure from the over-worked software defined "x" usage (you pick "x" such as data center, networking, storage, marketing, etc).

This is good news as we now have IoX where "X" can be leveraged from Things (IoT) and Devices (IoD) to People, Places, Protocols or Platforms (IoP), not to mention APIs, Applications and Apple (IoA).

How about Internet of Items (IoI) or Internet of Objects (IoO)?

We are already seeing Cisco with Internet of Everything (IoE) from CES and rest assured the Big Data folks will want to get all over IoBD while storage folks serve up Internet of Storage (IoS), granted that might be a little close to Apple’s OS for comfort of some.

Of course this should also prompt the question of if instead of Internet of Things (IoT) or IoX as being public, then would a Intranet of Things or other items (e.g. IoX) be considered private?

And if you just said or thought, what hybrid, sure, why not, its 2014 after all…

Here’s my point

There are many other variations particular if you apply some cloud and virtual based Big Data analytics with some software defined marketing creativity.

So what’s your take on IoT, IoD, IoP and other IoX, is it all IoH (Internet of Hype) and Internet of Marketing (IoM), something new to get excited about for those who suffer from technology buzzword ADD?

What say you?

Ok, nuff said

Goodbye 2013, hello 2014, predictions past, present and future

Storage I/O trends

Good by 2013 and hello 2014 along with predictions past, present and future

First, for those who may have missed this, thanks to all who helped make 2013 a great year!

2013 season greetings

Looking back at 2013 I saw a continued trend of more vendors and their media public relations (PR) people reaching out to have their predictions placed in articles, posts, columns or trends perspectives pieces.

Hmm, maybe a new trend is predictions selfies? ;)

Not to worry, this is not a wrapper piece for a bunch of those pitched and placed predictions requests that I received in 2013 as those have been saved for a rainy or dull day when we need to have some fun ;) .

What about 2013 server storage I/O networking, cloud, virtual and physical?

2013 end up with some end of year spree’s including Avago acquiring storage I/O and networking vendor LSI for about $6.6B USD (e.g. SSD cards, RAID cards, cache cards, HBA’s (Host Bus Adapters), chips and other items) along with Seagate buying Xyratex for about $374M USD (a Seagate suppliers and a customer partner).

Xyratex is known by some for making the storage enclosures that house hard disk drive (HDD’s) and Solid State Device (SSD) drives that are used by many well-known, and some not so well-known systems and solution vendors. Xyratex also has other pieces of their business such as appliances that combine their storage enclosures for HDD and SSD’s along with server boards, along with a software group focus on High Performance Compute (HPC) Lustre. There is another part of the Xyratex business that is not as well-known which is the test equipment used by disk drive manufacturers such as Seagate as part of their manufacturing process. Thus the Seagate acquisition moves them up market with more integrated solutions to offer to their (e.g. Seagate and Xyratex) joint customers, as well as streamline their own supply chain and costs (not to mention sell equipment to the other remaining drive manufactures WD and Toshiba).

Storage I/O trends

Other 2013 acquisitions included (Whiptail by Cisco, Virident by WD (who also bought several other companies), Softlayer by IBM) along with various mergers, company launches, company shutdowns (cloud storage Nirvanix and SSD maker OCZ bankruptcy filing), and IPO’s (some did well like Nimble while Violin not so well), while earlier high-flying industry darlings such as FusionIO are now the high-flung darling targets of the shareholder sock lawsuit attorneys.

2013 also saw the end of SNW (Storage Network World), jointly produced by SNIA and Computerworld Storage in the US after more than a decade. Some perspectives from the last US SNW held October 2013 can be found in the Fall 2013 StorageIO Update Newsletter here, granted those were before the event was formal announced as being terminated.

Speaking of events, check out the November 2013 StorageIO Update Newsletter here for perspectives from attending the Amazon Web Services (AWS) re:Invent conference which joins VMworld, EMCworld and a bunch of other vendor world events.

Lets also not forget Dell buying itself in 2013.

StorageIO in the news

Click on the following links read (and here) more about various 2013 industry perspectives trends commentary of mine in various venues, along with tips, articles, newsletters, events, pod cast, videos and other items.

What about 2014?

Perhaps 2014 will build on the 2013 momentum of the annual rights of pages refereed to as making meaningless future year trends and predictions as being passe?

Not that there is anything wrong with making predictions for the coming year, particular if they actually have some relevance, practicality not to mention track record.

However that past few years seems to have resulted in press releases along with product (or services) plugs being masked as predictions, or simply making the same predictions for the coming year that did not come to be for the earlier year (or the one before that or before that and so forth).

On the other hand, from an entertainment perspective, perhaps that’s where we will see annual predictions finally get classified and put into perspectives as being just that.

Storage I/O trends

Now for those who still cling to as well as look forward to annual predictions, ok, simple, we will continue in 2014 (and beyond) from where we left off in 2013 (and 2012 and earlier) meaning more (or continued):

  • Software defined "x" (replace "x" with your favorite topic) industry discussion adoption yet customer adoption or deployment question conversations.

  • Cloud conversations shifted from lets all go to the cloud as the new shiny technology to questioning the security, privacy, stability, vendor or service viability not to mention other common sense concerns that should have been discussed or looked into earlier. I have also heard from people who say Amazon (as well as Verizon, Microsoft, Blue host, Google, Nirvanix, Yahoo and the list goes on) outages are bad for the image of clouds as they shake people’s confidences. IMHO people confidence needs to be shaken to that of having some common sense around clouds including don’t be scared, be ready, do your homework and basic due diligence. This means cloud conversations over concerns set the stage for increased awareness into decision-making, usage, deployment and best practices (all of which are good things for continued cloud deployments). However if some vendors or pundits feel that people having basic cloud concerns that can be addressed is not good for their products or services, I would like to talk with them because they may be missing an opportunity to create long-term confidence with their customers or prospects.

  • VDI as a technology being deployed continues to grow (e.g. customer adoption) while the industry adoption (buzz or what’s being talked about) has slowed a bit which makes sense as vendors jump from one bandwagon to the new software defined bandwagon.

  • Continued awareness around modernizing data protection including backup/restore, business continuance (BC), disaster recovery (DR), high availability, archiving and security means more than simply swapping out old technology for new, yet using it in old ways. After all, in the data center and information factory not everything is the same. Speaking of data protection, check out the series of technology neutral webcast and video chats that started last fall as part of BackupU brought to you by Dell. Even though Dell is the sponsor of the series (that’s a disclosure btw ;) ) the focus of the sessions is on how to use different tools, technologies and techniques in new ways as well as having the right tools for different tasks. Check out the information as well as register to get a free Data Protection chapter download from my book Cloud and Virtual Data Storage Networking (CRC Press) at the BackupU site as well as attend upcoming events.

  • The nand flash solid state devices (SSD) cash-dash (and shakeout) continues with some acquisitions and IPO’s, as well as disappearances of some weaker vendors, while appearance of some new. SSD is showing that it is real in several ways (despite myths, fud and hype some of which gets clarified here) ranging from some past IPO vendors (e.g. FusiuonIO) seeing exit of their CEO and founders while their stock plummets and arrival of shareholder investor lawsuits, to Violins ho-hum IPO. What this means is that the market is real, it has a very bright future, however there is also a correction occurring showing that reality may be settling in for the long run (e.g. next couple of decades) vs. SSD being in the realm of unicorns.

    • Storage I/O trends

  • Internet of Things (IoT) and Internet of Devices (IoD) may give some relief for Big Data, BYOD, VDI, Software Defined and Cloud among others that need a rest after they busy usage that past few years. On the other hand, expect enhanced use of earlier buzzwords combined with IoT and IOD. Of course that also means plenty of questions around what is and is not IoD along with IoT and if actually relevant to what you are doing.

  • Also in 2014 some will discover storage and related data infrastructure topics or some new product / service thus having a revolutionary experience that storage is now exciting while others will have a DejaVu moment that it has been exciting for the past several years if not decades.

  • More big data buzz as well as realization by some that a pragmatic approach opens up a bigger broader market, not to mention customers more likely to realize they have more in common with big data than it simply being something new forcing them to move cautiously.

  • To say that OpenStack and related technologies will continue to gain both industry and customer adoption (and deployment) status building off of 2013 in 2014 would be an understatement, not to mention too easy to say, or leave out.

  • While SSD’s continue to gain in deployment, after the question is not if, rather when, where, with what and how much nand flash SSD is in your future, HDD’s continue to evolve for physical, virtual and cloud environments. This also includes Seagate announcing a new (Kinetic) Ethernet attached HDD (note that this is not a NAS or iSCSI device) that uses a new key value object storage API for storing content data (more on this in 2014).

  • This also means realizing that large amounts of little data can result in back logs of lots of big data, and that big data is growing into very fast big data, not to mention realization by some that HDFS is just another distributed file system that happens to work with Hadoop.

  • SOHO’s and lower end of SMB begin to get more respect (and not just during the week of Consumer Electronic Show – CES).

  • Realization that there is a difference between Industry Adoption and Customer Deployment, not to mention industry buzz and traction vs. customer adoption.

server storage I/O trends

What about beyond 2014?

That’s easy, many of the predictions and prophecies that you hear about for the coming year have also been pitched in prior years, so it only makes sense that some of those will be part of the future.

  • If you have seen or experienced something you are more likely to have DejaVu.
  • Otoh if you have not seen or experienced something you are more likely to have a new and revolutionary moment!
  • Start using new (and old) things in new ways vs. simply using new things in old ways.
  • Barrier to technology convergence, not to mention new technology adoption is often people or their organizations.
  • Convergence is still around, cloud conversations around concerns get addressed leading to continued confidence for some.
  • Realization that data infrastructure span servers, storage I/O networking, cloud, virtual, physical, hardware, software and services.
  • That you can not have software defined without hardware and hardware defined requires software.
  • And it is time for me to get a new book project (or two) completed in addition to helping others with what they are working on, more on this in the months to come…

Here’s my point

The late Jim Morrison of the Doors said "There are things known and things unknown and in between are the doors.".

The doors via Amazon.com
Above image and link via Amazon.com

Hence there is what we know about 2013 or will learn about the past in the future, then there is what will be in 2014 as well as beyond, hence lets step through some doors and see what will be. This means learn and leverage lessons from the past to avoid making the same or similar mistakes in the future, however doing so while looking forward without a death grip clinging to the past.

Needless to say there will be more to review, preview and discuss throughout the coming year and beyond as we go from what is unknown through doors and learn about the known.

Thanks to all who made 2013 a great year, best wishes to all, look forward to seeing and hearing from you in 2014!

Small Medium Business (SMB) IT continues to gain respect, what about SOHO?

Storage I/O trends

Blog post: Small Medium Business (SMB) IT continues to gain respect, what about SOHO?

Note that in Information Technology (IT) conversations there are multiple meanings for SMB including Server Message Block aka Microsoft Windows CIFS (Common Internet File System) along with its SAMBA implementation, however for this piece the context is Small Medium Business.

A decade or so ago, mention SMB (Small Medium Business) to many vendors, particular those who were either established or focused on the big game enterprise space and you might have gotten a condescending look or answer if not worse.

In other words, a decade ago the SMB did not get much respect from some vendors and those who followed or covered them.

Fast forward to today and many of those same vendors along with their pundits and media followers have now gotten their SMB grove, lingo, swagger or social media footsteps, granted for some that might be at the higher end of SMB also known as SME (Small Medium Enterprise).

Today in general the SMB is finally getting respect and in some circles its down right cool and trendy vs. being perceived as old school, stodgy large enterprise. Likewise the Remote Office Branch Office (ROBO) gained more awareness and coverage a few years back which while the ROBO buzz has subsided, the market and opportunities are certainly there.

What about Small Office Home Office (SOHO) today?

I assert that SOHO today is getting the same lack of respect that SMB in general received a decade ago.

IMHO the SOHO environment and market today is being treated with a similar lack of respect that the larger SMB received a decade ago.

Granted there are some vendors and their followings who are seeing the value and opportunity, not to mention market size potential of expanding their portfolios, not to mention routes to markets to meet their different needs of the SOHO.

relative enterprise sme smb soho positioning

What is the SOHO market or environment

One of the challenges with SMB, SOHO among other classifications are just that, the classifications.

Some classificaitons are based on number of employees, others on number of servers or workstations, while others are based on revenue or even physical location.

Meanwhile some are based on types of products, technologies or tools while others are tied to IT or general technology spending.

Some confuse the SOHO space with the consumer market space or sector which should not be a surprise if you view market segments as enterprise, SMB and consumer. However if you take a more pragmatic approach, between true consumer and SMB space, there lies the SOHO space. For some the definitions of what is consumer, SOHO, SMB, SME and enterprise (among others) will be based on number of employees, or revenue amount. Yet for others the categories may be tied to IT spending (e.g. price bands), number of workstations, servers, storage space capacity or some other metric. On the other hand some definitions of what is consumer vs. SOHO vs. SMB vs. SME or enterprise will be based on product capabilities, size, feature function and cost among other attributes.

Storage I/O trends

Understanding the SOHO

Keep in mind that SOHO can also overlap with Remote Office Branch Office (ROBO), not to mention blend with high-end consumer (prosumer) or lower bounds of SMB.

Part of the challenge (or problem) is that many confuse the Home Office or HO aspect of SOHO as being consumer.

Likewise many also confuse the Small Office or SO part of SOHO as being just the small home office or the virtual office of a mobile worker.

The reality is that just as the SMB space has expanded, there is also a growing area just above where consumer markets exist and where many place the lower-end of SMB (e.g. the bottom limits of where the solutions fit).

First keep in mind that many put too much focus and mistakenly believe that the HO or Home Office part of SOHO means that this is just a consumer focused space.

The reality is that while the HO gets included as part of SOHO, there is also the SO or Small Office which is actually the low-end of the SMB space.

Keep in mind that there are more:
SOHO than SMB
SMB than SME
SME than enterprise
F500 (Fortune 500) than F100
F100 than F10 and so forth.

Here is my point

SOHO does not have to be the Rodney Dangerfield of IT (e.g. gets no respect)!

If you jumped on the SMB bandwagon a decade ago, start paying attention to what’s going on with the SOHO or lower-end SMB sector. The reasons are simple, just as SMBs can grow up to be larger SMBs or SME or enterprise, SOHOs can also evolve to become SMBs either in business size, or in IT and data infrastructure needs, requirements.

For those who prefer (at least for now) look down upon or ignore the SOHO similar to what was done with SMB before converting to SMBism, do so at your own risk.

However let me be clear, this does not mean ignore or shift focus and thus disrupt or lose coverage of other areas, rather, extend, expand and at least become aware of what is going on in the SOHO space.

Server virtualization nested and tiered hypervisors

Storage I/O trends

Server virtualization nested and tiered hypervisors

A few years ago I did a piece (click here) about the then emerging trend of tiered hypervisors, particular using different products or technologies in the same environment.

Tiered snow tools
Tiered snow management tools and technologies

Tiered hypervisors can be as simple as using different technologies such as VMware vSphere/ESXi, Microsoft Hyper-V, KVM or Xen in your environment on different physical machines (PMs) for various business and application purposes. This is similar to having different types or tiers of technology including servers, storage, networks or data protection to meet various needs.

Another aspect is nesting hypervisors on top of each other for testing, development and other purposes.

nested hypervisor

I use nested VMware ESXi for testing various configurations as well as verifying new software when needed, or creating a larger virtual environment for functionality simulations. If you are new to nesting which is running a hypervisor on top of another hypervisor such as ESXi on ESXi or Hyper-V on ESXi here are a couple of links to get you up to speed. One is a VMware knowledge base piece, two are from William Lam (@lamw) Virtual Ghetto (getting started here and VSAN here) and the other is from Duncan Epping @DuncanYB Yellow Bricks sites.

Recently I did a piece over at FedTech titled 3 Tips for Maximizing Tiered Hypervisors that looks at using multiple virtualization tools for different applications and how they can give a number of benefits.

Here is an excerpt:

Tiered hypervisors can be run in different configurations. For example, an agency can run multiple server hyper­visors on the same physical blade or server or on separate servers. Having different tiers or types of hypervisors for server and desktop virtualization is similar to using multiple kinds of servers or storage hardware to meet different needs. Lower-cost hypervisors may have lacked some functionality in the past, but developers often add powerful new capabilities, making them an excellent option.

IT administrators who are considering the use of tiered or multiple hypervisors should know the answers to these questions:

  • How will the different hypervisors be managed?
  • Will the environment need new management tools for backup, monitoring, configuration, provisioning or other routine functions?
  • Do existing tools offer support for different hypervisors?
  • Will the hypervisors have dedicated PMs or be nested?
  • How will IT migrate virtual machines and their guests between different hypervisors? For example if using VMware and Hyper-V, will you use VMware vCenter Multi-Hypervisor Manager or something similar?

So how about it, how are you using and managing tiered hypervisors?

Ok, nuff said for now.

StorageIO Industry Trends and Perspectives

Industry trends: Amazon Web Services (AWS) re:Invent

Last week I attended the AWS re:Invent event in Las Vegas. This was the second annual AWS re:Invent conference which while having an AWS and cloud theme, it is also what I would describe as a data infrastructure event.

As a data infrastructure event AWS re:Invent spans traditional legacy IT and applications to newly invented, re-written, re-hosted or re-platformed ones from existing and new organizations. By this I mean a mix of traditional IT or enterprise people as well as cloud and virtual geek types (said with affection and all due respect of course) across server (operating system, software and tools), storage (primary, secondary, archive and tools), networking, security, development tools, applications and architecture.

That also means management from application and data protection spanning High Availability (HA), Business Continuance (BC), Disaster Recovery (DR), backup/restore, archiving, security, performance and capacity planning, service management among other related themes across public, private, hybrid and community cloud environments or paradigms. Hmm, I think I know of a book that covers the above and other related topic themes, trends, technologies and best practices called Cloud and Virtual Data Storage Networking (CRC Press) available via Amazon.com in print and Kindle (among other) versions.

During the event AWS announced enhanced and new services including:

  • WorkSpaces (Virtual Desktop Infrastructure – VDI) announced as a new service for cloud based desktops across various client devices including laptops, Kindle Fire, iPad and Android tablets using PCoIP.
  • Kinesis which is a managed service for real-time processing of streaming (e.g. Big) data at scale including ability to collect and process hundreds of GBytes of data per second across hundreds of thousands of data sources. On top of Kinesis you can build your big data applications or conduct analysis to give real-time key performance indicator dashboards, exception and alarm or event notification and other informed decision-making activity.
  • EC2 C3 instances provide Intel Xeon E5 processors and Solid State Device (SSD) based direct attached storage (DAS) like functionality vs. EBS provisioned IOPs for cost-effective storage I/O performance and compute capabilities.
  • Another EC2 enhancement are G2 instance that leverage high performance NVIDIA GRID GPU with 1,536 parallel processing cores. This new instance is well suited for 3D graphics, rendering, streaming video and other related applications that need large-scale parallel or high performance compute (HPC) also known as high productivity compute.
  • Redshift (cloud data warehouse) now supports cross region snapshots for HA, BC and DR purposes.
  • CloudTrail records AWS API calls made via the management console for analytics and logging of API activity.
  • Beta of Trusted Advisor dashboard with cost optimization saving estimates including EBS and provisioned IOPs
  • Relational Database Service (RDS) support for PostgresSQL including multi-AZ deployment.
  • Ability to discover and launch various software from AWS Marketplace via the EC2 Console. The AWS Marketplace for those not familiar with it is a catalog of various software or application titles (over 800 products across 24 categories) including free and commercial licensed solutions that include SAP, Citrix, Lotus Notes/Domino among many others.
  • AppStream is a low latency (STX protocol based) service for streaming resource (e.g. compute, storage or memory) intensive applications and games from AWS cloud to various clients, desktops or mobile devices. This means that the resource intensive functionality can be shifted to the cloud, while providing a low latency (e.g. fast) user experience off-loading the client from having to support increased compute, memory or storage capabilities. Key to AppStream is the ability to stream data in a low-latency manner including over networks normally not suited for high quality or bandwidth intensive applications. IMHO AppStream while focused initially on mobile app’s and gaming, being a bit streaming technology has the potential to be used for other similar functions that can leverage download speed improvements.

    • When I asked an AWS person if or what role AppStream might have or related to WorkSpaces their only response was a large smile and no comment. Does this mean WorkSpaces leverages AppStream? Candidly I don’t know, however if you look deeper into AppStream and expand your horizons, see what you can think up in terms of innovation. Updated 11/21/13 AWS has provided clarification that WorkSpaces is based on PCoIP while AppStream uses the STX protocols.

    Check out AWS Sr. VP Andy Jassy keynote presentation here.

Overall I found the AWS re:Invent event to be a good conference spanning many aspects and areas of focus which means I will be putting it on my must attend list for 2014.

Part II: EMC announces XtremIO General Availability, speeds and feeds

Storage I/O trends

XtremIO flash SSD more than storage I/O speed

Following up part I of this two-part series, here are more more details, insights and perspectives about EMC XtremIO and it’s generally availability that were announced today.

XtremIO the basics

  • All flash Solid State Device (SSD) based solution
  • Cluster of up to four X-Brick nodes today
  • X-Bricks available in 10TB increments today, 20TB in January 2014
  • 25 eMLC SSD drives per X-Brick with redundant dual processor controllers
  • Provides server-side iSCSI and Fibre Channel block attachment
  • Integrated data footprint reduction (DFR) including global dedupe and thin provisioning
  • Designed for extending duty cycle, minimizing wear of SSD
  • Removes need for dedicated hot spare drives
  • Capable of sustained performance and availability with multiple drive failure
  • Only unique data blocks are saved, others tracked via in-memory meta data pointers
  • Reduces overhead of data protection vs. traditional small RAID 5 or RAID 6 configurations
  • Eliminates overhead of back-end functions performance impact on applications
  • Deterministic  storage I/O performance (IOPs, latency, bandwidth) over life of system

When would you use XtremIO vs. another storage system?

If you need all enterprise like data services including thin provisioning, dedupe, resiliency with deterministic performance on an all-flash system with raw capacity from 10-40TB (today) then XtremIO could be a good fit. On the other hand, if you need a mix of SSD based storage I/O performance (IOPS, latency or bandwidth) along with some HDD based space capacity, then a hybrid or traditional storage system could be the solution. Then there are hybrid scenarios where a hybrid storage system, array or appliance (mix of SSD and HDD) are used for most of the applications and data, with an XtremIO handling more tasks that are demanding.

How does XtremIO compare to others?

EMC with XtremIO is taking a different approach than some of their competitors whose model is to compare their faster flash-based solutions vs. traditional mid-market and enterprise arrays, appliances or storage systems on a storage I/O IOP performance basis. With XtremIO there is improved performance measured in IOPs or database transactions among other metrics that matter. However there is also an emphasis on consistent, predictable, quality of service (QoS) or what is known as deterministic storage I/O performance basis. This means both higher IOPs with lower latency while doing normal workload along with background data services (snapshots, data footprint reduction, etc).

Some of the competitors focus on how many IOPs or work they can do, however without context or showing impact to applications when back-ground tasks or other data services are in use. Other differences include how cluster nodes are interconnected (for scale out solutions) such as use of Ethernet and IP-based networks vs dedicated InfiniBand or PCIe fabrics. Host server attachment will also differ as some are only iSCSI or Fibre Channel block, or NAS file, or give a mix of different protocols and interfaces.

An industry trend however is to expand beyond the flash SSD need for speed focus by adding context along with QoS, deterministic behavior and addition of data services including snapshots, local and remote replication, multi-tenancy, metering and metrics, security among other items.

Storage I/O trends

Who or what are XtremIO competition?

To some degree vendors who only have PCIe flash SSD cards might place themselves as the alternative to all SSD or hybrid mixed SSD and HDD based solutions. FusionIO used to take that approach until they acquired NexGen (a storage system) and now have taken a broader more solution balanced approach of use the applicable tool for the task or application at hand.

Other competitors include the all SSD based storage arrays, systems or appliance vendors which includes legacy existing as well as startups vendors that include among others IBM who bought TMS (flashsystems), NetApp (EF540), Solidfire, Pure, Violin (who did a recent IPO) and Whiptail (bought by Cisco).  Then there are the hybrid which is a long list including Cloudbyte (software), Dell, EMCs other products, HDS, HP, IBM, NetApp, Nexenta (Software), Nimble, Nutanix, Oracle, Simplivity and Tintri among others.

What’s new with this XtremIO announcement

10TB X-Bricks enable 10 to 40TB (physical space capacity) per cluster (available on 11/19/13). 20TB X-Bricks (larger capacity drives) will double the space capacity in January 2014. If you are doing the math, that means either a single brick (dual controller) system, or up to four bricks (nodes, each with dual controllers) configurations. Common across all system configurations are data features such as thin provisioning, inline data footprint reduction (e.g. dedupe) and XtremIO Data Protection (XDP).

What does XtremIO look like?

XtremIO consists of up to four nodes (today) based on what EMC calls X-Bricks.
EMC XtremIO X-Brick
25 SSD drive X-Brick

Each 4U X-Brick has 25 eMLC SSD drives in a standard EMC 2U DAE (disk enclosure) like those used with the VNX and VMAX for SSD and Hard Disk Drives (HDD). In addition to the 2U drive shelve, there are a pair of 1U storage processors (e.g. controllers) that give redundancy and shared access to the storage shelve.

XtremIO Architecture
XtremIO X-Brick block diagram

XtremIO storage processors (controllers) and drive shelve block diagram. Each X-Brick and their storage processors or controllers communicate with each other and other X-Bricks via a dedicated InfiniBand using Remote Direct Memory Access (RDMA) fabric for memory to memory data transfers. The controllers or storage processors (two per X-Brick) each have dual processors with eight cores for compute, along with 256GB of DRAM memory. Part of each controllers DRAM memory is set aside as a mirror its partner or peer and vise versa with access being over the InfiniBand fabric.

XtremIO fabric
XtremIO X-Brick four node fabric cluster or instance

How XtremIO works

Servers access XtremIO X-Bricks using iSCSI and Fibre Channel for block access. A responding X-Brick node handles the storage I/O request and in the case of a write updates other nodes. In the case of a write, the handling node or controller (aka storage processor) checks its meta data map in memory to see if the data is new and unique. If so, the data gets saved to SSD along with meta data information updated across all nodes. Note that data gets ingested and chunked or sharded into 4KB blocks. So for example if a 32KB storage I/O request from the server arrives, that is broken (e.g. chunk or shard) into 8 4KB pieces each with a mathematical unique fingerprint created. This fingerprint is compared to what is known in the in memory meta data tables (this is a hexadecimal number compare so a quick operation). Based on the comparisons if unique the data is saved and pointers created, if already exists, then pointers are updated.

In addition to determining if unique data, the fingerprint is also used for generate a balanced data dispersal plan across the nodes and SSD devices. Thus there is the benefit of reducing duplicate data during ingestion, while also reducing back-end IOs within the XtremIO storage system. Another byproduct is the reduction in time spent on garbage collection or other background tasks commonly associated with SSD and other storage systems.

Meta data is kept in memory with a persistent copied written to reserved area on the flash SSD drives (think of as a vault area) to support and keep system state and consistency. In between data consistency points the meta data is kept in a log journal like how a database handles log writes. What’s different from a typical database is that XtremIO XIOS platform software does these consistency point writes for persistence on a granularity of seconds vs. hours or minutes.

Storage I/O trends

What about rumor that XtremIO can only do 4KB IOPs?

Does this mean that the smallest storage I/O or IOP that XtremIO can do is 4GB?

That is a rumor or some fud I have heard floated by a competitor (or two or three) that assumes if only 4KB internal chunk or shard being used for processing, that must mean no IOPs smaller than 4KB from a server.

XtremIO can do storage I/O IOP sizes of 512 bytes (e.g. the standard block size) as do other systems. Note that the standard server storage I/O block or IO size is 512 bytes or multiples of that unless the new 4KB advanced format (AF) block size being used which based on my conversations with EMC, AF is not supported, yet. (Updated 11/15/13 EMC has indicated that host (front-end) 4K AF support, along with 512 byte emulation modes are available now with XIOS). Also keep in mind that since XtremIO XIOS internally is working with 4KB chunks or shards, that is a stepping stone for being able to eventually leverage back-end AF drive support in the future should EMC decide to do so (Updated 11/15/13 Waiting for confirmation from EMC about if back-end AF support is now enabled or not, will give more clarity as it is recieved).

What else is EMC doing with XtremIO?

  • VCE Vblock XtremIO systems for SAP HANA (and other databases) in memory databases along with VDI optimized solutions.
  • VPLEX and XtremIO for extended distance local, metro and wide area HA, BC and DR.
  • EMC PowerPath XtremIO storage I/O path optimization and resiliency.
  • Secure Remote Support (aka phone home) and auto support integration.

Boosting your available software license minutes (ASLM) with SSD

Another use of SSD has been in the past the opportunity to make better use of servers stretching their usefulness or delaying purchase of new ones by improving their effective use to do more work. In the past this technique of using SSDs to delay a server or CPU upgrade was used when systems when hardware was more expensive, or during the dot com bubble to fill surge demand gaps.  This has the added benefit of stretching database and other expensive software licenses to go further or do more work. The less time servers spend waiting for IOP’s means more time for doing useful work and bringing value of the software license. Otoh, the more time spent waiting is lot available software minutes which is cost overhead.

Think of available software licence minutes (ASLM) in terms of available software license minutes where if doing useful work your software is providing value. On the other hand if those minutes are not used for useful work (e.g. spent waiting or lost due to CPU or server or IO wait, then they are lost). This is like airlines and available seat miles (ASM) metric where if left empty it’s a lost opportunity, however if used, then value, not to mention if yield management applied to price that seat differently. To make up for that loss many organizations have to add extra servers and thus more software licensing costs.

Storage I/O trends

Can we get a side of context with them metrics?

EMC along with some other vendors are starting to give more context with their storage I/O performance metrics that matter than simple IOP’s or Hero Marketing Metrics. However context extends beyond performance to also availability and space capacity which means data protection overhead. As an example, EMC claims 25% for RAID 5 and 20% for RAID 6 or 30% for RAID 5/RAID 6 combo where a 25 drive (SSD) XDP has a 8% overhead. However this assumes a 4+1 (5 drive) RAID , not apples to apples comparison on a space overhead basis. For example a 25 drive RAID 5 (24+1) would have around an 4% parity protection space overhead or a RAID 6 (23+2) about 8%.

Granted while the space protection overhead might be more apples to apples with the earlier examples to XDP, there are other differences. For example solutions such as XDP can be more tolerant to multiple drive failures with faster rebuilds than some of the standard or basic RAID implementations. Thus more context and clarity would be helpful.

StorageIO would like see vendors including EMC along with startups who give data protection space overhead comparisons without context to do so (and applaud those who provide context). This means providing the context for data protection space overhead comparisons similar to performance metrics that matter. For example simply state with an asterisk or footnote comparing a 4+1 RAID 5 vs. a 25 drive erasure or forward error correction or dispersal or XDP or wide stripe RAID for that matter (e.g. can we get a side of context). Note this is in no way unique to EMC and in fact quite common with many of the smaller startups as well as established vendors.

General comments

My laundry list of items which for now would be nice to have’s, however for you might be need to have would include native replication (today leverages Recover Point), Advanced Format (4KB) support for servers (Updated 11/15/13 Per above, EMC has confirmed that host/server-side (front-end) AF along with 512 byte emulation modes exist today), as well as SSD based drives, DIF (Data Integrity Feature), and Microsoft ODX among others. While 12Gb SAS server to X-Brick attachment for small in the cabinet connectivity might be nice for some, more practical on a go forward basis would be 40GbE support.

Now let us see what EMC does with XtremIO and how it competes in the market. One indicator to watch in the industry and market of the impact or presence of EMC XtremIO is the amount of fud and mud that will be tossed around. Perhaps time to make a big bowl of popcorn, sit back and enjoy the show…

Ok, nuff said (for now).

EMC announces XtremIO General Availability (Part I)

Storage I/O trends

EMC announces XtremIO flash SSD General Availability

EMC announced today the general availability (GA) if the all flash Solid State Device (SSD) XtremIO that they acquired a little over a year ago. Earlier this year EMC announced directed availability (DA) of the EMC version of XtremIO as part of other SSD hardware and software updates (here and here). The XtremIO GA announcement also follows that of the VNX2 or MCx released in September of this year that also has flash SSD enhancements along with doing more with available resources.

EMC XtremIO flash SSD boosting storage I/O performance

As an industry trend, the question is not if SSD is in your future, rather where, when, how much, what to use along with coexistence to complement Hard Disk Drive (HDD) based solutions in some environments. This also means that SSD is like real estate where location matters, not to mention having different types of technologies, packaging, solutions to meet various needs (and price points). This all ties back to the best server and storage I/O or IOP is the one that you do know have to do, the second best is the one with the least impact and best application benefit.

From industry adoption to customer deployment

EMC has evolved the XtremIO platform from a pre-acquisition solution to an first EMC version that was offered to an early set of customers e.g. DA.

I suspect that the DA was as much a focus on getting early customer feedback, addressing immediate needs or opportunities as wells as getting the EMC sales and marketing teams messaging, marching orders aligned and deployed. The latter would be rather important to decrease or avoid the temptation to cannibalize existing product sales with the shiny new technology (SNT). Likewise, it would be important for EMC to not create isolated pockets or fenced off products as some other vendors often do.

EMC XtremIO X-Brick
25 SSD drive X-Brick

What is being announced?

  • General availability vs. directed or limited availability
  • Version 2.2 of the XIOS platform software
  • Integrating with EMC support and service tools

Let us get back go this announcement and XtremIO of which EMC has indicated that they have several customers who have now done either $1M or $5M USD deals. EMC has claimed over 1.5 PBytes have been booked and deployed, or with data footprint reduction (DFR) including dedupe over 10PB effective capacity. Note that for those who are focused on dedupe or DFR reduction ratios 10:1.5 may not be as impressive as seen with some backup solutions, however keep in mind that this is for primary high performance storage vs. secondary or tertiary storage devices.

As part of this announcement, EMC has also release V2.2 of the XtremIO platform software (XIOS). Hence a normal new product should start with a version 1.0 at launch, however as explained this is both a new version of the technology as well as the initial GA by EMC.

Also as part of this announcement, EMC is making available XtremIO 10TB X-Bricks with 25 eMLC SSD drives each, along with dual controllers (storage processors). EMC has indicated that it will make available a 20TB X-Brick using larger capacity SSD drives in January 2014. Note that the same type of SSD drives must be used in the systems. Currently there can be up to four X-Bricks per XtremIO cluster or instance that are interconnected using a dedicated InfiniBand Fabric. Application servers access the XtremIO X-Bricks using standard Fibre Channel or Ethernet and IP based iSCSI. In addition to the hardware platform items, the XtremIO platform software (XIOS) includes built-in on the fly data footprint reduction (DFR) using global dedupe during data ingestion and placement. Other features include thin provisioning, VMware VAII, data protection and self-balancing data placement.

Storage I/O trends

Who or what applications are XtremIO being positioned for?

Some of XtremIO industry sectors include:

  • Financial and insurance services
  • Medical, healthcare and life sciences
  • Manufacturing, retail and warehouse management
  • Government and defense
  • Media and entertainment

Application and workload focus:

  • VDI including replacing linked clones with ability to do full clone without overhead
  • Server virtualization where aggregation causes aggravation with many mixed IOPs
  • Database for reducing latency, boosting IOPs as well as improving software license costs.

Databases such as IBM DB2, Oracle RAC, Microsoft SQLserver and MySQL among others have traditionally for decades been a prime opportunity for SSD (DRAM and flash). This also includes newer NoSQL or key value stores and meta data repositories for object such as Mongo, Hbase, Cassandra, Riak among others. Typical focus includes placing entire instances, or specific files and objects such as indices, journals and redo logs, import/export temp or scratch space, message queries and high activity tables among others.

What about overlap with other EMC products?

If you simply looked at the above list of sectors (among others) or applications, you could easily come to a conclusion that there is or would be overlap. Granted in some environments there will be which means XtremIO (or other vendors solutions) may be the primary storage solution. On the other hand since everything is not the same in most data centers or information factories, there will be a mix of storage systems handling various tasks. This is where EMC will need to be careful learning what they did during DA on where to place XtremIO and how to positing to complement when and where needed other solutions, or as applicable being a replacement.

XtremIO Announcement Summary

  • All flash SSD storage solution with iSCSI and Fibre Channel server attachment
  • Scale out and scale up performance while keeping latency low and deterministic
  • Enhanced flash duty cycle (wear leveling) to increase program / erase (P/E) cycles durability
  • Can complement other storage systems, arrays or appliances or function as a standalone
  • Coexists and complements host side caching hardware and software
  • Inline always on data footprint reduction (DFR) including dedupe (global dedupe without performance compromise), space saving snapshots and copies along with thin provisioning

Storage I/O trends

Some General Comment and Perspectives

Overall, XtremIO gives EMC and their customers, partners and prospects a new technology to use and add to their toolbox for addressing various challenges. SSD is in your future, when, where, with what and how are questions not to mention how much. After all, a bit of flash SSD in the right location used effectively can have a large impact. On the other hand, a lot of flash SSD in the wrong place or not used effectively will cost you lots of cash. Key for EMC and their partners will be to articulate clearly, where XtremIO fits vs. other solutions without adding complexity.

Checkout part II of this series to learn more about XtremIO including what it is, how it works, competition and added perspectives.

DataDynamics StorageX 7.0 file and data management migration software

Storage I/O trends

DataDynamics StorageX 7.0 file and data management migration software

Some of you may recall back in 2006 (here and here) when Brocade bought a file management storage startup called NuView whose product was StorageX, and then in 2009 issued end of life (EOL) notice letters that the solution was being discontinued.

Fast forward to 2013 and there is a new storage startup (DatraDynamics) with an existing product that was just updated and re-released called StorageX 7.0.

Software Defined File Management – SDFM?

Granted from an industry buzz focused adoption perspective you may not have heard of DataDynamics or perhaps even StorageX. However many other customers around the world from different industry sectors have as well as are using the solution.

The current industry buzz is around software defined data centers (SDDC) which has lead to software defined networking (SDN), software defined storage (SDS), and other software defined marketing (SDM) terms, not to mention Valueware. So for those who like software defined marketing or software defined buzzwords, you can think of StorageX as software defined file management (SDFM), however don’t ask or blame them about using it as I just thought of it for them ;).

This is an example of industry adoption traction (what is being talked about) vs. industry deployment and customer adoption (what is actually in use on a revenue basis) in that DataDynamics is not a well-known company yet, however they have what many of the high-flying startups with industry adoption don’t have which is an installed base with revenue customers that also now have a new version 7.0 product to deploy.

StorageX 7.0 enabling intelligent file and data migration management

Thus, a common theme is adding management including automated data movement and migration to carry out structure around unstructured NAS file data. More than a data mover or storage migration tool, Data Dynamics StorageX is a software platform for adding storage management structure around unstructured local and distributed NAS file data. This includes heterogeneous vendor support across different storage system, protocols and tools including Windows CIFS and Unix/Linux NFS.

Storage I/O image

A few months back prior to its release, I had an opportunity to test drive StorageX 7.0 and have included some of my comments in this industry trends perspective technology solution brief (PDF). This solution brief titled Data Dynamics StorageX 7.0 Intelligent Policy Based File Data Migration is a free download with no registration required (as are others found here), however per our disclosure policy to give transparency, DataDynamics has been a StorageIO client.

If you have a new for gaining insight and management control around your file unstructured data to support migrations for upgrades, technology refresh, archiving or tiering across different vendors including EMC and NetApp, check out DataDynamics StorageX 7.0, take it for a test drive like I did and tell them StorageIO sent you.

Some fall 2013 AWS cloud storage and compute enhancements

Storage I/O trends

Some fall 2013 AWS cloud storage and compute enhancements

I just received via Email the October Amazon Web Services (AWS) Newsletter in advance of the re:Invent event next week in Las Vegas (yes I will be attending).

AWS October newsletter and enhancement updates

What this means

AWS is arguably the largest of the public cloud services with a diverse set of services and options across multiple geographic regions to meet different customer needs. As such it is not surprising to see AWS continue to expand their service offerings expanding their portfolio both in terms of features, functionalities along with extending their presences in different geographies.

Lets see what else AWS announces next week in Las Vegas at their 2013 re:Invent event.

Click here to view the current October 2013 AWS newsletter. You can view (and signup for) earlier AWS newsletters here, and while you are at it, view the current and recent StorageIO Update newsletters here.

What does gaining industry traction or adoption mean too you?

Storage I/O trends

What does gaining industry traction or adoption mean too you?

Is it based on popularity or how often something that is talked about, blogged, tweeted, commented, video or similar?

What are the indicators that something is gaining traction?

Perhaps it is tied to the number of press releases, product or staffing announcements including who has joined the organization along with added coverage of it?

Maybe its based on how many articles, videos or some other content and coverage that helps to show traction and momentum?

On the other hand is it tied to how many prospects are actually trying a product or service as part of a demo or proof of concept?

Then again, maybe it is associated with how many real paying or revenue installed footprints and customers or what is also known as industry deployment (customer adoption).

Of those customers actually buying and deploying, how many have continued using the technology even after industry adoption subsides or does the solution become shelf ware?

Does the customer deployment actually continue to rise quietly while industry adoption or conversations drop off (past the cycle of hype)?

buzzword bingo

Gaining context with industry traction

Gaining traction can mean different things to people, however there is also a difference between industry adoption (what’s being talked about among the industry) and industry deployment (what customers are actually buying, installing and continue to use).

Often the two can go hand in hand, usually one before the other, however they can also be separate. For example it is possible that something new will have broad industry adoption (being talked about) yet have low customer deployment (even over time). This occurs when something is new and interesting that might be fun to talk about or the vendor, solution provider is cool and fun to hang out and be with, or simply has cool giveaways.

On the other hand there can be customer deployment and adoption with little to no fan fare (industry adoption) for different reasons.

Storage I/O trends

Here’s my point

Not long ago if you asked or listened to some, you would think that once high-flying cloud storage vendor Nirvanix was gaining traction based on their marketing along with other activities, yet they recently closed their doors. Then there was Kim Dotcoms hyped Megacloud launch earlier this year that also has now gone dark or shutting down. This is not unique to cloud service providers or solutions as the same can, has and will happen again to traditional hardware, software and services providers (startups and established).

How about former high-flying FusionIO, or the new startup by former FusionIO founder and CEO David Flynn called Primary Data. One of the two is struggling to gain or keep up revenue traction while having declined in industry popularity traction. The other is gaining in industry popularity traction with their recently secured $50 Million in funding yet are still in stealth mode so rather difficult to gain customer adoption or deployment traction (thus for now its industry adoption focus for them ;).

in the news

If you are a customer or somebody actually deploying and using technology, tools, techniques and services for real world activity vs. simply trying new things out, your focus on what is gaining traction will probably be different than others. Granted it is important to keep an eye on what is coming or on futures, however there is also the concern of how it will really work and keep working over time.

For example while Hard Disk Drives (HDD) continue to support industry deployment traction (customer adoption and usage) traction. However they are not new and when new models apear (such as Seagate Ethernet based Kinetic) they may not get the same industry adoption traction as a newer technology might. Case in point Solid State Devices (SSD) continue to gain in customer deployment adoption with some environments doing more than others, yet have very high industry adoption traction status.

Storage I/O SSD trends
Relative SSD customer adoption and deployment along with future opportunities

On the other hand if your focus is on what’s new and emerging which is usually more industry centered, then it should be no surprise what traction means and where it is focused. For example the following figure shoes where different audiences have various timelines on adoption (read more here).

SSD trends
Current and emerging memory, flash and other SSD technologies for different audiences

Wrap up

When you hear that something is gaining traction, ask yourself (or others) what that means along with the applicable context.

Does that mean something is popular and trending to discuss (based on GQ or looks), or that it is actually gaining real customer adoption based on G2 (insight – they are actually buying vs. simply trying our a free version).

Does it mean one form of traction along with industry adoption (what’s being talked about) vs. industry deployment (real customer adoption) is better than the other?

No, it simply means putting things into the applicable context.

Ok, nuff said (for now).

Fall 2013 StorageIO Update Newsletter

Storage I/O trends

Fall 2013 StorageIO Update Newsletter

Welcome to the Fall 2013 (joint September and October) edition of the StorageIO Update (newsletter) containing trends perspectives on cloud, virtualization and data infrastructure topics. It is fall (at least here in north America) which means conferences, symposium, virtual and physical events, seminars, webinars in addition to normal client project activities. Starting with VMworld back in late August, that event occurred in San Francisco which kicked off the fall (or back to school) season of activity. VMworld was followed with many other events including in-person along with virtual or on-line such as webinars, Google+ hangouts among others, not to mention all the briefings for vendor product announcements and updates. Check out the industry trends perspectives articles, comments and blog posts below that covers some activity over the past few months.

VMworld 2013
Congratulations to VMworld on the 10th anniversary of the event. With the largest installment yet of a VMworld in terms of attendance, there were also many announcements. Here are a synopsis of some of those announcements which of course included plenty of software defined marketing (SDM).

CMG and Storage Performance
During mid-September I was invited to give an industry trends and perspectives presentation to the Storage Performance Council (SPC) board. The SPC board were meeting in the Minneapolis area and I gave a brief talk about Metrics that Matter and importance of context with focus on applications. Speaking of the Minneapolis area, Tom Becchetti (@tbecchetti) organized a great CMG event hosted over at Blue Cross Blue Shield of Minnesota. I gave a discussion around Technolutionary, technology evolution and revolution, using old and new things in new ways.

Check out our backup, restore, BC, DR and archiving (Under the resources section on StorageIO.com) for various presentation, book chapter downloads and other content.

SNW Fall 2013 Long Beach
Talking about traveling, there was a quick trip out to Long Beach for the fall 2013 edition of Storage Networking World (SNW) where I had some good meetings and conversations with those who were actually there. No need to sugar coat it, likewise no need to kick sand in its face. Plain and simple, SNW is not the event it used to be has been a common discussion theme for several years which I had set my expectation accordingly.

Some have asked me why I even spent time, money and resources to attend SNW?

My answer is that I had some meetings to attend to, wanted to see and meet with others who were going to be there, and perhaps even say goodbye to an event that I have been involved with for over a decade.

Does that mean I’m all done with SNW?

Not sure yet as will have to wait and see what SNIA and IDG/Computerworld the event co-owners and producers put together for future events. However there are enough other events and activities to pick up the slack which is part of what has caused the steady decline in events like SNW among others.

Perhaps it is time for SNIA to partner with another adjacent yet like-minded organization such as CMG to collaborate and try doing something like what was done in the early 2000s? That is SNIA providing their own seminars along with others such as myself who involved with both CMG, SNW and SNIA to beef up or set up a storage and I/O focused track at the CMG event.

Beyond those items mentioned above, or in the following section, there are plenty of interesting and exciting things occurring in the background that I cant talk about yet. However watch for future posts, commentary, perspectives and other information down the road (and in the not so distant future).

Enjoy this edition of the StorageIO Update newsletter.

Brouwer Storage Consultancy

StorageIO in Europe (Netherlands)
Spent over a week in the Netherlands where I presented three different seminar workshop sessions organized by Brouwer Storage Consultancy who is celebrating their 10th anniversary in business. These sessions spanned five full days of interactive discussions with an engaged diverse group of attendees in the Nijkerk area who came from across Holland to take part in these workshops.

Congratulations to Gert and Frank Brouwer on their ten years of being in business and best wishes for many more. Fwiw those who are curious StorageIO will be ten years young in business in about two years.

StorageIO Industry Trends and Perspectives

Some observations from while in Europe:

Continued cloud privacy concerns amplified by NSA and suspicion of US-based companies, yet many are not aware of similar concerns of European or UK-based firms from those outside those areas. While there were some cloud concern conversations over the demise of Nirvanix, those seemed less so then in the media or US given that at least in Holland they have seen other cloud and storage as a service firms come and go already. It should be noted that the US has also seen cloud and storage as a service startups come and go, however I think sometimes we or at least the media tends to have a short if not selective memory at times.

In one of our workshops sessions we were talking about service level objectives (SLO), service level agreements (SLA), recovery point objectives (RPO) and recovery time objectives (RTO) among other themes. Somebody mentioned why the focus of time in RPO and questions why not a transactional perspective which I thought was a brilliant question. We had a good conversation in the group and concurred that while RPO is what the industry uses, that there also needs to be a transactional state context tie to what is inferred or assumed with RPO and RTO. Thus the importance of looking beyond just the point in time, however the importance of a transactional context or state, such as not just the time, however to a given transactional point.

Note that transactional could mean database, file system, backup or data protection index or catalog, meta data repository or other entity. This is where some should be jumping up and down like Donkey in Shrek wanting to point out that is exactly what RTO and RPO refer to which would be great. However all to often what is assumed is not conveyed, thus those who don’t know, well, they assume or simply don’t know what others.

StorageIO Industry Trends and Perspectives

Data Dynamics StorageX 7.0 Intelligent Policy Based File Data Migration – There is no such thing as a data or information recession . Likewise, people and data are living longer as well as getting larger. These span various use cases from traditional to personal or at work productivity. From little to big data content, collaboration including file or document sharing to rich media applications all of which are leveraging unstructured data. For example, email, word processing back-office documents, web and text files, presentations (e.g. PowerPoint), photos, audio and video among others. These macro trends result in the continued growth of unstructured Network Attached Storage (NAS) file data.

Thus, a common theme is adding management including automated data movement and migration to carry out structure around unstructured NAS file data. More than a data mover or storage migration tool, Data Dynamics StorageX is a software platform for adding storage management structure around unstructured local and distributed NAS file data. This includes heterogeneous vendor support across different storage system, protocols and tools including Windows CIFS and Unix/Linux NFS.

Cloud conversations: Has Nirvanix shutdown caused cloud confidence concerns?

Storage I/O trends

Cloud conversations: Has Nirvanix shutdown caused cloud confidence concerns?

Recently seven plus year old cloud storage startup Nirvanix announced that they were finally shutting down and that customers should move their data.

nirvanix customer message

Nirvanix has also posted an announcement that they have established an agreement with IBM Softlayer (read about that acquisition here) to help customers migrate to those services as well as to those of Amazon Web Services (AWS), (read more about AWS in this primer here), Google and Microsoft Azure.

Cloud customer concerns?

With Nirvanix shutting down there has been plenty of articles, blog posts, twitter tweets and other conversations asking if Clouds are safe.

Btw, here is a link to my ongoing poll where you can cast your vote on what you think about clouds.

IMHO clouds can be safe if used in safe ways which includes knowing and addressing your concerns, not to mention following best practices, some of which pre-date the cloud era, sometimes by a few decades.

Nirvanix Storm Clouds

More on this in a moment, however lets touch base on Nirvanix and why I said they were finally shutting down.

The reason I say finally shutting down is that there were plenty of early warning signs and storm clouds circling Nirvanix for a few years now.

What I mean by this is that in their seven plus years of being in business, there have been more than a few CEO changes, something that is not unheard of.

Likewise there have been some changes to their business model ranging from selling their software as a service to a solution to hosting among others, again, smart startups and establishes organizations will adapt over time.

Nirvanix also invested heavily in marketing, public relations (PR) and analyst relations (AR) to generate buzz along with gaining endorsements as do most startups to get recognition, followings and investors if not real customers on board.

In the case of Nirvanix, the indicator signs mentioned above also included what seemed like a semi-annual if not annual changing of CEOs, marketing and others tying into business model adjustments.

It was only a year or so ago that if you gauged a company health by the PR and AR news or activity and endorsements you would have believed Nirvanix was about to crush Amazon, Rackspace or many others, perhaps some actually did believe that, followed shortly there after by the abrupt departure of their then CEO and marketing team. Thus just as fast as Nirvanix seemed to be the phoenix rising in stardom their aura started to dim again, which could or should have been a warning sign.

This is not to solo out Nirvanix, however given their penchant for marketing and now what appears to some as a sudden collapse or shutdown, they have also become a lightning rod of sort for clouds in general. Given all the hype and fud around clouds when something does happen the distract ors will be quick to jump or pile on to say things like "See, I told you, clouds are bad".

Meanwhile the cloud cheerleaders may go into denial saying there are no problems or issues with clouds, or they may go back into a committee meeting to create a new stack, standard, API set marketing consortium alliance. ;) On the other hand, there are valid concerns with any technology including clouds that in general there are good implementations that can be used the wrong way, or questionable implementations and selections used in what seem like good ways that can go bad.

This is not to say that clouds in general whether as a service, solution or product on a public, private or hybrid bases are any riskier than traditional hardware, software and services. Instead what this should be is a wake up call for people and organizations to review clouds citing their concerns along with revisiting what to do or can be done about them.

Clouds: Being prepared

Ben Woo of Neuralytix posted this question comment to one of the Linked In groups Collateral Considerations If You Were/Are A Nirvanix Customer which I posted some tips and recommendations including:

1) If you have another copy of your data somewhere else (which you should btw), how will your data at Nirvanix be securely erased, and the storage it resides on be safely (and secure) decommissioned?

2) if you do have another copy of your data elsewhere, how current is it, can you bring it up to date from various sources (including update from Nirvanix while they stay online)?

3) Where will you move your data to short or near term, as well as long-term.

4) What changes will you make to your procurement process for cloud services in the future to protect against situations like this happening to you?

5) As part of your plan for putting data into the cloud, refine your strategy for getting it out, moving it to another service or place as well as having an alternate copy somewhere.

Fwiw any data I put into a cloud service there is also another copy somewhere else which even though there is a cost, there is a benefit, The benefit is that ability to decide which to use if needed, as well as having a backup/spare copy.

Cloud Concerns and Confidence

As part of cloud procurement as services or products, the same proper due diligence should occur as if you were buying traditional hardware, software, networking or services. That includes checking out not only the technology, also the companies financial, business records, customer references (both good and not so good or bad ones) to gain confidence. Part of gaining that confidence also involves addressing ahead of time how you will get your data out of or back from that services if needed.

Keep in mind that if your data is very important, are you going to keep it in just one place? For example I have data backed-up as well as archived to cloud providers, however I also have local copies either on-site or off.

Likewise there is data I have local kept at alternate locations including cloud. Sure that is costly, however by not treating all of my data and applications the same, I’m able to balance those costs out, plus use cost advantages of different services as well as on-site to be effective. I may be spending no less on data protection, in fact I’m actually spending a bit more, however I also have more copies and versions of important data and in multiple locations. Data that is not changing often does not get protected as often, however there are multiple copies to meet different needs or threat risks.

Don’t be scared of clouds, be prepared

While some of the other smaller cloud storage vendors will see some new customers, I suspect that near to mid-term, it will be the larger, more established and well funded providers that gain the most from this current situation. Granted some customers are looking for alternatives to the mega cloud providers such as Amazon, Google, HP, IBM, Microsoft and Rackspace among others, however there are a long list of others some of which who are not so well-known that should be such as Centurylink/Savvis, Verizon/Terremark, Sungurd, Dimension Data, Peak, Bluehost, Carbonite, Mozy (owned by EMC), Xerox ACS, Evault (owned by Seagate) not to mention a long list of many others.

Something to be aware of as part of doing your due diligence is determining who or what actually powers a particular cloud service. The larger providers such as Rackspace, Amazon, Microsoft, HP among others have their own infrastructure while some of the smaller service providers may in fact use one of the larger (or even smaller) providers as their real back-end. Hence understanding who is behind a particular cloud service is important to help decide the viability and stability of who it is you are subscribed to or working with.

Something that I have said for the past couple of years and a theme of my book Cloud and Virtual Data Storage Networking (CRC Taylor & Francis) is do not be scared of clouds, however be ready, do your homework.

This also means having cloud concerns is a good thing, again don’t be scared, however find what those concerns are along with if they are major or minor. From that list you can start to decide how or if they can be worked around, as well as be prepared ahead of time should you either need all of your cloud data back quickly, or should that service become un-available.

Also when it comes to clouds, look beyond lowest cost or for free, likewise if something sounds too good to be true, perhaps it is. Instead look for value or how much do you get per what you spend including confidence in the service, service level agreements (SLA), security, and other items.

Keep in mind, only you can prevent data loss either on-site or in the cloud, granted it is a shared responsibility (With a poll).
