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.

Ok, nuff said (for now).

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.

Seagate Kinetic Cloud and Object Storage I/O platform (and Ethernet HDD)

Storage I/O trends

Seagate Kinetic Cloud and Object Storage I/O platform

Seagate announced today their Kinetic platform and drive designed for use by object API accessed storage including for cloud deployments. The Kinetic platform includes Hard Disk Drives (HDD) that feature 1Gb Ethernet (1 GbE) attached devices that speak object access API or what Seagate refers to as a key / value.

Seagate Kinetic architecture

What is being announced with Seagate Kinetic Cloud and Object (Ethernet HDD) Storage?

  • Kinetic Open Storage Platform – Ethernet drives, key / value (object access) API, partner software
  • Software developer’s kits (SDK) – Developer tools, documentation, drive simulator, code libraries, code samples including for SwiftStack and Riak.
  • Partner ecosystem

What is Kinetic?

While it has 1 GbE ports, do not expect to be able to use those for iSCSI or NAS including NFS, CIFS or other standard access methods. Being Ethernet based, the Kinetic drive only supports the key value object access API. What this means is that applications, cloud or object stacks, key value and NoSQL data repositories, or other software that adopt the API can communicate directly using object access.

Seagate Kinetic storage

Internal, the HDD functions as a normal drive would store and accessing data, the object access function and translation layer shifts from being in an Object Storage Device (OSD) server node to inside the HDD. The Kinetic drive takes on the key value API personality over 1 GbE ports instead of traditional Logical Block Addressing (LBA) and Logical Block Number (LBN) access using 3g, 6g or emerging 12g SAS or SATA interfaces. Instead Kinetic drives respond to object access (aka what Seagate calls key / value) API commands such as Get, Put among others. Learn more about object storage, access and clouds at www.objectstoragecenter.com.

Storage I/O trends

Some questions and comments

Is this the same as what was attempted almost a decade ago now with the T10 OSD drives?

Seagate claims no.

What is different this time around with Seagate doing a drive that to some may vaguely resemble the predecessor failed T10 OSD approach?

Industry support for object access and API development have progressed from an era of build it and they will come thinking, to now where the drives are adapted to support current cloud, object and key value software deployment.

Wont 1GbE ports be too slow vs. 12g or 6g or even 3g SAS and SATA ports?

Keep in mind those would be apples to oranges comparisons based on the protocols and types of activity being handled. Kinetic types of devices initially will be used for large data intensive applications where emphasis is on storing or retrieving large amounts of information, vs. low latency transactional. Also, keep in mind that one of the design premises is to keep cost low, spread the work over many nodes, devices to meet those goals while relying on server-side caching tools.

Storage I/O trends

Does this mean that the HDD is actually software defined?

Seagate or other HDD manufactures have not yet noticed the software defined marketing (SDM) bandwagon. They could join the software defined fun (SDF) and talk about a software defined disk (SDD) or software defined HDD (SDHDD) however let us leave that alone for now.

The reality is that there is far more software that exists in a typical HDD than what is realized. Sure some of that is packaged inside ASICs (Application Specific Integrated Circuits) or running as firmware that can be updated. However, there is a lot of software running in a HDD hence the need for power yet energy-efficient processors found in those devices. On a drive per drive basis, you may see a Kinetic device consume more energy vs. other equivalence HDDs due to the increase in processing (compute) needed to run the extra software. However that also represents an off-load of some work from servers enabling them to be smaller or do more work.

Are these drives for everybody?

It depends on if your application, environment, platform and technology can leverage them or not. This means if you view the world only through what is new or emerging then these drives may be for all of those environments, while other environments will continue to leverage different drive options.

Object storage access

Does this mean that block storage access is now dead?

Not quite, after all there is still some block activity involved, it is just that they have been further abstracted. On the other hand, many applications, systems or environments still rely on block as well as file based access.

What about OpenStack, Ceph, Cassandra, Mongo, Hbase and other support?

Seagate has indicated those and others are targeted to be included in the ecosystem.

Seagate needs to be careful balancing their story and message with Kinetic to play to and support those focused on the new and emerging, while also addressing their bread and butter legacy markets. The balancing act is communicating options, flexibility to choose and adopt the right technology for the task without being scared of the future, or clinging to the past, not to mention throwing the baby out with the bath water in exchange for something new.

For those looking to do object storage systems, or cloud and other scale based solutions, Kinetic represents a new tool to do your due diligence and learn more about.

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.

cloud storage

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.

Storage I/O trends

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.

Storage I/O trends

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).

Cisco buys Whiptail continuing the SSD storage I/O flash cash cache dash

Storage I/O trends

Cisco buys Whiptail continuing the Storage storage I/O flash cash cache dash

Congratulations to Virident for being bought today for $645 Million USD by Western Digital (WD). Virident a nand flash PCIe card startup vendor has been around for several years and in the last year or two has gain more industry awareness as a competitor to FusionIO among others.

There is a nand flash solid state devices (SSD) cash-dash occurring, not to mention fast cache dances that is occurring the IT and data infrastructure (e.g. storage and IO) sector specifically.

Why the nand flash SSD cash dash and cache dance?

Yesterday hard disk drive (HDD) vendor Western Digital (WD) bought Virident a nand flash PCIe Solid State Device (SSD) card vendor for $650M, and today networking and server vendor Cisco bought Whiptail a SSD based storage system startup for a little over $400M. Here is an industry trends perspective post that I did yesterday on WD and Virident.

Obviously this begs a couple of questions, some of which I raised in my post yesterday about WD, Virident, Seagate, FusionIO and others.

Questions include

Does this mean Cisco is getting ready to take on EMC, NetApp, HDS and its other storage partners who leverage the Cisco UCS server?

IMHO at least near term no more than they have in the past, nor any more than EMCs partnership with Lenovo indicates a shift in what is done with vBlocks. On the other hand, some partners or customers may be as nervous as a long-tailed cat next to a rocking chair (Google it if you don’t know what it means ;).

Is Cisco going to continue to offer Whiptail SSD storage solutions on a standalone basis, or pull them in as part of solutions similar to what it has done on other acquisitions?

Storage I/O trends

IMHO this is one of the most fundamental questions and despite the press release and statements about this being a UCS focus, a clear sign of proof for Cisco is how they reign in (if they go that route) Whiptail from being sold as a general storage solution (with SSD) as opposed to being part of a solution bundle.

How will Cisco manage its relationship in a coopitition manner cooperating with the likes of EMC in the joint VCE initiative along with FlexPod partner NetApp among others? Again time will tell.

Also while most of the discussions about NetApp have been around the UCS based FlexPod business, there is the other side of the discussion which is what about NetApp E Series storage including the SSD based EF540 that competes with Whiptail (among others).

Many people may not realize how much DAS storage including fast SAS, high-capacity SAS and SATA or PCIe SSD cards Cisco sells as part of UCS solutions that are not vBlock, FlexPod or other partner systems.

NetApp and Cisco have partnerships that go beyond the FlexPod (UCS and ONTAP based FAS) so will be interesting to see what happens in that space (if anything). This is where Cisco and their UCS acquiring Whiptail is not that different from IBM buying TMS to complement their servers (and storage) while also partnering with other suppliers, same holds true for server vendors Dell, HP, IBM and Oracle among others.

Can Cisco articulate and convince their partners, customers, prospects and others that the whiptail acquisition is more about direct attached storage
(DAS) which includes both internal dedicated and external shared device?

Keep in mind that DAS does not have to mean Dumb A$$ Storage as some might have you believe.

Then there are the more popular questions of who is going to get bought next, what will NetApp, Dell, Seagate, Huawei and a few others do?

Oh, btw, funny how have not seen any of the pubs mention that Whiptail CEO Dan Crain is a former Brocadian (e.g. former Brocade CTO) who happens to be a Cisco competitor, just saying.

Congratulations to Dan and his crew and enjoy life at Cisco.

Stay tuned as the fall 2013 nand flash SSD cache dash and cash dance activities are well underway.

Ok, nuff said (for now).

Is more of something always better? Depends on what you are doing

Storage I/O trends

Is more always better? Depends on what you are doing

As with many things it depends, however how about some of these?

Is more better for example (among others):

  • Facebook likes
  • Twitter followers or tweets (I’m @storageio btw)
  • Google+ likes, follows and hangouts
  • More smart phone apps
  • LinkedIn connections
  • People in your circle or community
  • Photos or images per post or article
  • People working with or for you
  • Partners vs. doing more with those you have
  • People you are working for or with
  • Posts or longer posts with more in them
  • IOPs or SSD and storage performance
  • Domains under management and supported
  • GB/TB/PB/EB supported or under management
  • Mart-time jobs or a better full-time opportunity
  • Metrics vs. those that matter with context
  • Programmers to get job done (aka mythical man month)
  • Lines of code per cost vs. more reliable and tested code per cost
  • For free items and time spent managing them vs. more productivity for a nominal fee
  • Meetings for planning on what to do vs. streamline and being more productive
  • More sponsors or advertisers or underwriters vs. fewer yet more effective ones
  • Space in your booth or stand at a trade show or conference vs. using what you have more effectively
  • Copies of the same data vs. fewer yet more unique (not full though) copies of information
  • Patents in your portfolio vs. more technology and solutions being delivered
  • Processors, sockets, cores, threads vs. using them more effectively
  • Ports and protocols vs. using them more effectively

Storage I/O trends

Thus does more resources matter, or making more effective use of them?

For example more ports, protocols, processors, cores, sockets, threads, memory, cache, drives, bandwidth, people among other things is not always better, particular if those resources are not being used effectively.

Likewise don’t confuse effective with efficient often assumed to mean used.

For example a cache or memory may be 100% used (what some call efficient) yet only providing a 35% effective benefit (cache hit or miss) vs. cache turn (misses etc).

Throwing more processing power in terms of clock speed, or cores is one thing, kind of like throwing more server blades at a software problem vs. using those cores and sockets not to mention threads more effectively.

Good software will run better on fast hardware while enabling more to be done with the same or less.

Thus with better software or tools, more work can be done in an effective way leveraging those resources vs. simply throwing or applying more at the situation.

Hopefully you get the point, so no need to do more with this post (for now), if not, stay tuned and pay more attention around you.

Ok, nuff said, I need to go get more work done now.

Cheers

VMworld 2013 Vmware, server, storage I/O and networking update (Day 1)

Storage I/O trends

Congratulations to VMware on 10 years of VMworld!

With the largest installment yet of a VMworld in terms of attendance, there were also many announcements today (e.g. Monday) and many more slated for out the week. Here are a synopsis of some of those announcements.

Software Defined Data Center (SDDC) and Software Defined Networks (SDN)

VMware made a series of announcements today that set the stage for many others. Not surprisingly, these involved SDDC, SDN, SDS, vSphere 5.5 and other management tool enhancements, or the other SDM (Software Defined Management).

VMworld image

Here is a synopsis of what was announced by VMware.

VMware NSX (SDN) combines Nicira NVPTM along with vCloud Network and Security
VMware Virtual SAN (VSAN) not to be confused with virtual storage appliances (VSAs)
VMware vCloud Suite 5.5
VMware vSphere 5.5 (includes support for new Intel Xeon and Atom processors)
VMware vSphere App HA
VMware vSphere Flash Read Cache software
VMware vSphere Big Data Extensions
VMware vCloud Automation Center
VMware vCloud

Note that while these were announced today, some will be in public beta soon and general availability over the next few months or quarters (learn more here including pricing and availability). More on these and other enhancements in future posts. However for now check out what Duncan Epping (@DuncanYB) of VMware has to say over at his Yellowbook site here, here and here.

Additional VMworld Software Defined Announcements

Dell did some announcements as well for cloud and virtual environments in support of VMware from networking to servers, hardware and software. With all the recent acquisitions by Dell including Quest where they picked up Foglight management tools, along with vRanger, Bakbone and others, Dell has amassed an interesting portfolio. On the hardware front, check out the VRTX shared server infrastructure, I want one for my VMware environment, now I just need to justify one (to myself). Speaking of Dell, if you are at VMworld on Tuesday August 27 around 1:30PM stop by the Dell booth where I will be presenting including announcing some new things (stay tuned for more on that soon).

HP had some announcements today. HP jumped into the SDDC and SDN with some Software Defined Marketing (SDM) and Software Defined Announcements (SDA) in addition to using the Unified Data Center theme. Today’s announcements by HP were focused more around SDN and VMware NSX along with the HP Virtual Application Networks SDN Controller and VMware networking.

NetApp (Both #1417) announced more integration between their Data ONTAP based solutions and VMware vSphere, Horizon Suite, vCenter, vCloud Automation Center and vCenter Log Insight under the them theme of SDDC and SDS. As part of the enhancement, NetApp announced Virtual Storage Console (VSC 5.0) for end-to-end storage management and software in VMware environments. In addition, integration with VMware vCenter Server 5.5. Not to be left out of the SSD flash dash NetApp also released a new V1.2 of their FlashAccel software for vSphere 5.0 and 5.1.

Storage I/O trends

Cloud, Virtualization and DCIM

Here is one that you probably have not seen or heard much about elsewhere, which is Nlyte announcement of their V1.5 Virtualization Connector for Data Center Infrastructure Management (DCIM). Keep in mind that DCIM is more than facilities, power, and cooling related themes, particular in virtual data centers. Thus, some of the DCIM vendors, as well as others are moving into the converged DCIM space that spans server, storage, networking, hardware, software and facilities topics.

Interested in or want to know more about DCIM, and then check out these items:
Data Center Infrastructure Management (DCIM) and Infrastructure Resource Management (IRM)
Data Center Tools Can Streamline Computing Resources
Considerations for Asset Tracking and DCIM

Data Protection including Backup/Restore, BC, DR and Archiving

Quantum announced that Commvault has added support to use the Lattus object storage based solution as an archive target platform. You can learn more about object storage (access and architectures) here at www.objectstoragecenter.com .

PHD Virtual did a couple of data protection (backup/restore , BC, DR ) related announcements (here and here ). Speaking of backup/restore and data protection, if you are at VMworld on Tuesday August 27th around 1:30PM, stop by the Dell booth where I will be presenting, and stay tuned for more info on some things we are going to announce at that time.

In case you missed it, Imation who bought Nexsan earlier this year last week announced their new unified NST6000 series of storage systems. The NST6000 storage solutions support Fibre Channel (FC) and iSCSI for block along with NFS, CIFS/SMB and FTP for file access from virtual and physical servers.

Emulex announced some new 16Gb Fibre Channel (e.g. 16GFC) aka what Brocade wants you to refer to as Gen 5 converged and multi-port adapters. I wonder how many still remember or would rather forget how many ASIC and adapter gens from various vendors occurred just at 1Gb Fibre Channel?

Storage I/O trends

Caching and flash SSD

Proximal announced V2.0 of AutoCache 2.0 with role based administration, multi-hypervisor support (a growing trend beyond just a VMware focus) and more vCenter/vSphere integration. This is on the heels of last week’s FusionIO powered IBM Flash Cache Storage Accelerator (FCSA ) announcement, along with others such as EMC , Infinio, Intel, NetApp, Pernix, SanDisk (Flashsoft) to name a few.

Mellanox (VMworld booth #2005), you know, the Infinaband folks who also have some Ethernet (which also includes Fibre Channel over Ethernet) technology did a series of announcements today with various PCIe nand flash SSD card vendors. The common theme with the various vendors including Micron (Booth #1635) and LSI is in support of VMware virtual servers using iSER or iSCSI over RDMA (Remote Direct Memory Access). RDMA or server to server direct memory access (what some of you might know as remote memory mapped IO or channel to channel C2C) enables very fast low server to server data movement such as in a VMware cluster. Check out Mellanox and their 40Gb Ethernet along with Infinaband among other solutions if you are into server, storage i/o and general networking, along with their partners. Need or want to learn more about networking with your servers and storage check out Cloud and Virtual Data Storage Networking and Resilient Storage Networking .

Rest assured there are many more announcements and updates to come this week, and in the weeks to follow…

Ok, nuff said (for now).

IBM Server Side Storage I/O SSD Flash Cache Software

Storage I/O trends

IBM Server Side Storage I/O SSD Flash Cache Software

As I often say, the best server storage I/O or IOP is the one that you do not have to do. The second best storage I/O or IOP is the one with least impact or that can be done in a cost-effective way. Likewise the question is not if solid-state device (SSD) including nand flash are in your future, rather when, where, why, with what, how much along with from whom. Also location matters when it comes to SSD including nand flash with different environments and applications leveraging different placement (locality) options, not to mention how much performance do you need vs. want?

As part of their $1 billion USD (to be spent over three years, or $333.3333 million per year) flash ahead initiative IBM has announced their Flash Cache Storage Accelerator (FCSA) server software. While IBM did not use the term, (congratulations and thank you btw) some creative marketer might want to try calling this Software Defined Cache (SDC) or Software Defined SSD (SDSSD) which if that occurs, apologies in advance ;). Keep in mind that it was about a year ago this time when IBM announced that they were acquiring SSD industry veteran Texas Memory Systems (TMS).

What was announced, introducing Flash Cache Storage Acceleration or FCSA

With this announcement of FCSA slated for customer general availability by end of August, IBM joins EMC and NetApp among other storage systems vendors who developed their own, or have collaborated on server-side IO optimization and cache software. Some of the other startup and established vendors who have IO optimization, performance acceleration and caching software include DataRam (Ramdisk), FusionIO, Infinio (NFS for VMware), Pernix (block for VMware), Proximal and SANdisk (bought flashsoft) among others.

Read more about IBM Flash Cache Software (FCSA) including various questions and perspectives in part two of this two-part post located here.

Part II: IBM Server Side Storage I/O SSD Flash Cache Software

Storage I/O trends

Part II IBM Server Flash Cache Storage I/O accelerator for SSD

This is the second in a two-part post series on IBM’s Flash Cache Storage Accelerator (FCSA) for Solid State Device (SSD) storage announced today. You can view part I of the IBM FCSA announcement synopsis here.

Some FCSA ssd cache questions and perspectives

What is FCSA?
FCSA is a server-side storage I/O or IOP caching software tool that makes use of local (server-side) nand flash SSD (PCIe cards or drives). As a cache tool (view IBM flash site here) FCSA provides persistent read caching on IBM servers (xSeries, Flex and Blade x86 based systems) with write through cache (e.g. data cached for later reads) while write data is written directly to block attached storage including SANs. back-end storage can be iSCSI, SAS, FC or FCoE based block systems from IBM or others including all SSD, hybrid SSD or traditional HDD based solutions from IBM and others.

How is this different from just using a dedicated PCIe nand flash SSD card?
FCSA complements those by using them as a persistent storage to cache storage I/O reads to boost performance. By using the PCIe nand flash card or SSD drives, FCSA and other storage I/O cache optimization tools free up valuable server-side DRAM from having to be used as a read cache on the servers. On the other hand, caching tools such as FCSA also keep local cached reads closer to the applications on the servers (e.g. locality of reference) reducing the impact on backed shared block storage systems.

What is FCSA for?
With storage I/O or IOPS and application performance in general, location matters due to locality of reference hence the need for using different approaches for various environments. IBM FCSA is a storage I/O caching software technology that reduces the impact of applications having to do random read operations. In addition to caching reads, FCSA also has a write-through cache, which means that while data written to back-end block storage including on iSCSI, SAS, FC or FCoE based storage (IBM or other vendors), a copy of the data is cached for later reads. Thus while the best storage I/O is the one that does not have to be done (e.g. can be resolved from cache), the second best would be writes that go to a storage system that are not competing with read requests (handled via cache).

Storage I/O trends

Who else is doing this?
This is similar to what EMC initially announced and released in February 2012 with VFcache now renamed to be XtremSW along with other caching and IO optimization software from others (e.g. SANdisk, Proximal and Pernix among others.

Does this replace IBM EasyTier?
Simple answer is no, one is for tiering (e.g. EasyTier), the other is for IO caching and optimization (e.g. FCSA).

Does this replace or compete with other IBM SSD technologies?
With anything, it is possible to find a way to make or view it as competitive. However in general FCSA complements other IBM storage I/O optimization and management software tools such as EasyTier as well as leverage and coexist with their various SSD products (from PCIe cards to drives to drive shelves to all SSD and hybrid SSD solutions).

How does FCSA work?
The FCSA software works in either a physical machine (PM) bare metal mode with Microsoft Windows operating systems (OS) such as Server 2008, 2012 among others. There is also *nix support for RedHat Linux, along with in a VMware virtual machine (VM) environment. In a VMware environment High Availability (HA), DRS and VMotion services and capabilities are supported. Hopefully it will be sooner vs. later that we hear IBM do a follow-up announcement (pure speculation and wishful thinking) on more hypervisors (e.g. Hyper-V, Xen, KVM) support along with Centos, Ubuntu or Power based systems including IBM pSeries. Read more about IBM Pure and Flex systems here.

What about server CPU and DRAM overhead?
As should be expected, a minimal amount of server DRAM (e.g. main memory) and CPU processing cycles are used to support the FCSA software and its drivers. Note the reason I say as should be expected is how you can have software running on a server doing any type of work that does not need some amount of DRAM and processing cycles. Granted some vendors will try to spin and say that there is no server-side DRAM or CPU consumed which would be true if they are completely external to the server (VM or PM). The important thing is to understand how much of an impact in terms of CPU along with DRAM consumed along with their corresponding effectiveness benefit that are derived.

Storage I/O trends

Does FCSA work with NAS (NFS or CIFS) back-end storage?
No this is a server-side block only cache solution. However having said that, if your applications or server are presenting shared storage to others (e.g. out the front-end) as NAS (NFS, CIFS, HDFS) using block storage (back-end), then FCSA can cache the storage I/O going to those back-end block devices.

Is this an appliance?
Short and simple answer is no, however I would not be surprised to hear some creative software defined marketer try to spin it as a flash cache software appliance. What this means is that FCSA is simply IO and storage optimization software for caching to boost read performance for VM and PM servers.

What is this hardware or storage agnostic stuff mean?
Simple, it means that FCSA can work with various nand flash PCIe cards or flash SSD drives installed in servers, as well as with various back-end block storage including SAN from IBM or others. This includes being able to use block storage using iSCSI, SAS, FC or FCoE attached storage.

What is the difference between Easytier and FCSA?
Simple, FCSA is providing read acceleration via caching which in turn should offload some reads from affecting storage systems so that they can focus on handling writes or read ahead operations. Easytier on the other hand is for as its name implies tiering or movement of data in a more deterministic fashion.

How do you get FCSA?
It is software that you buy from IBM that runs on an IBM x86 based server. It is licensed on a per server basis including one-year service and support. IBM has also indicated that they have volume or multiple servers based licensing options.

Storage I/O trends

Does this mean IBM is competing with other software based IO optimization and cache tool vendors?
IBM is focusing on selling and adding value to their server solutions. Thus while you can buy the software from IBM for their servers (e.g. no bundling required), you cannot buy the software to run on your AMD/Seamicro, Cisco (including EMC/VCE and NetApp) , Dell, Fujitsu, HDS, HP, Lenovo, Oracle, SuperMicro among other vendors servers.

Will this work on non-IBM servers?
IBM is only supporting FCSA on IBM x86 based servers; however, you can buy the software without having to buy a solution bundle (e.g. servers or storage).

What is this Cooperative Caching stuff?
Cooperative caching takes the next step from simple read cache with write-through to also support chance coherency in a shared environment, as well as leverage tighter application or guest operating system and storage system integration. For example, applications can work with storage systems to make intelligent predictive informed decisions on what to pre-fetch or read ahead and cached, as well as enable cache warming on restart. Another example is where in a shared storage environment if one server makes a change to a shared LUN or volume that the local server-side caches are also updated to prevent stale or inconsistent reads from occurring.

Can FCSA use multiple nand flash SSD devices on the same server?
Yes, IBM FCSA supports use of multiple server-side PCIe and or drive based SSD devices.

How is cache coherency maintained including during a reboot?
While data stored in the nand flash SSD device is persistent, it’s up to the server and applications working with the storage systems to decide if there is coherent or stale data that needs to be refreshed. Likewise, since FCSA is server-side and back-end storage system or SAN agnostic, without cooperative caching it will not know if the underlying data for a storage volume changed without being notified from another server that modified it. Thus if using shared back-end including SAN storage, do your due diligence to make sure multi-host access to the same LUN’s or volumes is being coordinated with some server-side software to support cache coherency, something that would apply to all vendors.

Storage I/O trends

What about cache warming or reloading of the read cache?
Some vendors who have tightly interested caching software and storage systems, something IBM refers to as cooperative caching that can have the ability to re-warm the cache. With solutions that support cache re-warming, the cache software and storage systems work together to main cache coherency while pre-loading data from the underlying storage system based on hot bands or other profiles and experience. As of this announcement, FCSA does not support cache warming on its own.

Does IBM have service or tools to complement FCSA?
Yes, IBM has an assessment, profile and planning tool that are available on a free consultation services basis with a technician to check your environment. Of course, the next logical step would be for IBM to make the tool available via free download or on some other basis as well.

Do I recommend and have I tried FCSA?
On paper, or WebEx, YouTube or other venue FCSA looks interesting and capable, a good fit for some environments particular if IBM server-based. However since my PM and VMware VM based servers are from other vendors, along with the fact that FCSA only runs on IBM servers, have not actually given it a hands on test drive yet. Thus if you are looking at storage I/O optimization and caching software tools for your VM or PM environment, checkout IBM FCSA to see if it meets your needs.

General comments

It is great to see server and storage systems vendors add value to their solutions with I/O and performance optimization as well as caching software tools. However, I am also concerned with the growing numbers of different software tools that only work with one vendor’s servers or storage systems, or at least are supported as such.

This reminds me of a time not all that long ago (ok, for some longer than others) when we had a proliferation of different host bus adapter (HBA) driver and pathing drivers from various vendors. The result is a hodge podge (a technical term) of software running on different operating systems, hypervisors, PM’s, VMs, and storage systems, all of which need to be managed. On the other hand, for the time being perhaps the benefit will outweigh the pain of having different tools. That is where there are options from server-side vendor centric, storage system focused, or third-party software tool providers.

Another consideration is that some tools work in VMware environments; others support multiple hypervisors while others also support bare metal servers or PMs. Which applies to your environment will of course depend. After all, if you are an all VMware environment given that many of the caching tools tend to be VMware focused, that gives more options vs. for those who are still predominately PM environments.

Ok, nuff said (for now)
