Cloud and Virtual Data Storage Networking now on Kindle

It only makes sense that a book about Clouds, Virtualization, Data Storage and Networking be available via a cloud service in electronic format. Today Amazon and my publisher (CRC Press Taylor and Francis) released a Kindle version of my new book Cloud and Virtual Data Storage Networking which joins the previously released hardcopy version also available at Amazon.com among other venues.

Cloud and Virtual Data Storage Networking has been declared The New Enterprise Tech Bible by noted industry blogger and host of the Nekkid Tech (@NekkidTech) pod cast Greg Knieriemen (@Knieriemen). Check out Episode #11 (The Enterprise Tech Bible) of the Nekkid Tech pod cast show here.

Comments and reviews about Cloud and Virtual Data Storage Networking can be found at Amazon.com along with those from Stephen Guendert, PhD (@DrSteveGuendert) at CMG MeasureIT (@cmgnews) who says: Gregs latest book is the ibuprofen that will make these cloud computing information overload headaches go away. Cloud and Virtual Data Storage Networking is the single source you can read to get a clear understanding of the fundamentals of the cloud.

Greg Brunton, EDS, an HP Company commented: With all the chatter in the market about cloud storage and how it can solve all your problems, the industry needed a clear breakdown of the facts and how to use Cloud cloud storage effectively. Gregs latest book does exactly that.

What industry pundits love and loathe about data storage

Drew Robb has a good article about what IT industry pundits including vendors, analysts, and advisors loath including comments from myself.

In the article Drew asks: What do you really love about storage and what are your pet peeves?

One of my comments and perspectives is that I like Hybrid Hard Disk Drives (HHDDs) in addition to traditional Hard Disk Drives (HDD) along with Solid State Devices (SSDs). As much as I like HHDDs, I also believe that with any technology, they are not the best solution for everything, however they can also be used in many ways than being seen. Here is the fifth installment of a series on HHDDs that I have done since June 2010 when I received my first HHDD a Seagate Momentus XT. You can read the other installments of my momentus moments here, here, here and here.

Molly Rector VP of marketing at tape summit resources vendor Spectra Logic mentioned that what she does not like is companies that base their business plan on patent law trolling. I would have expected something different along the lines of countering or correcting people that say tape sucks, tape is dead, or that tape is the cause problem of anything wrong with storage thus clearing the air or putting up a fight that tape summit resources. Go figure…

Another of my comments involved clouds of which there are plenty of conversations taking place. I do like clouds (I even recently wrote a book involving them) however Im a fan of using them where applicable to coexist and enhance other IT resources. Dont be scared of clouds, however be ready, do your homework, listen, learn, do proof of concepts to decide best practices, when, where, what and how to use them.

Speaking of clouds, click here to read about who is responsible for cloud data loss and cast your vote, along with viewing what do you think about IT clouds in general here.

Mike Karp (aka twitter @storagewonk ) an analyst with Ptak Noel mentions that midrange environments dont get respect from big (or even startup) vendors.

I would take that a step further by saying compared to six or so years ago, SMB are getting night and day better respect along with attention by most vendors, however what is lacking is respect of the SOHO sector (e.g. lower end of SMB down to or just above consumer).

Granted some that have traditional sold into those sectors such as server vendors including Dell and HP get it or at least see the potential along with traditional enterprise vendor EMC via its Iomega . Yet I still see many vendors including startups in general discounting, shrugging off or sneering at the SOHO space similar to those who dissed or did not respect the SMB space several years ago. Similar to the SMB space, SOHO requires different products, packaging, pricing and routes to market via channel or etail mechanisms which means change for some vendors. Those vendors who embraced the SMB and realized what needed to change to adapt to those markets will also stand to do better with the SOHO.

Here is the reason that I think SOHO needs respect.

Simple, SOHOs grow up to become SMBs, SMBs grow up to become SMEs, SMEs grow up to become enterprises and not to mention that the amount of data being generated, moved, processed and stored continues to grow. The net result is that SMBs along with SOHO storage demands will continue to grow and for those vendors who can adjust to support those markets will also stand to gain new customers that in turn can become plans for other solution offerings.

Not surprising Eran Farajun of Asigra which has been doing cloud backups decades before they were known as clouds loves backup (and restores). However I am surprised that Eran did not jump on the its time to modernize and re architect data protection theme. Oh well, will have to have a chat with Eran on that sometime.

What was surprising were comments from Panzura who has a good distributed (e.g. read also cloud) file system that can be used for various things including online reference data. Panzura has a solution that normally I would not even think about in the context of being pulled into a Datadomain or dedupe appliance type discussion (e.g tape sucks or other similar themes). So it is odd that they are playing to the tape sucks camp and theme vs. playing to where the technology can really shine which IMHO is in the global, distributed, scale out and cloud file system space. Oh well, I guess you go with what you know or has worked in the past to get some attention.

Molly Rector of Spectra also mentioned that she likes High Performance Computing, surprised that she did not throw in high productivity computing as well in conjunction with big data, big bandwidth, green, dedupe, power, disk, tape and related buzzword bingo terms.

Also there are some comments from myself about cost cutting.

While I see the need for organizations to cut costs during tough economic times, Im not a fan of simply cutting cost for the sake of cost cutting as opposed to finding and removing complexity that in turn remove costs of doing work. In other words, Im a fan of finding and removing waste, becoming more effective and productive along with removing the cost of doing a particular piece of work. This in the end meets the aim of bean counters to cut costs, however can be done in a way that does not degrade service levels or customer service experience. For example instead of looking to cut backup costs, do you know where the real costs of doing data protection exist (hint swapping out media is treating the symptoms) and if so, what can be done to streamline those from the source of the problem downstream to the target (e.g. media or medium). In other words, redesign, review, modernize how data protection is done, leverage data footprint reduction (DFR) techniques including archive, compression, consolidation, data management, dedupe and other technologies in effective and creative ways, after all, return on innovation is the new ROI.

New Seagate Momentus XT Hybrid drive (SSD and HDD)

Seagate recently announced the next generation Momentus XT Hybrid Hard Disk Drive (HHDD) with a capacity of 750GB in a 2.5 inch form factor and MSRP of $245.00 USD including integrated NAND flash solid state device (SSD). As a refresher, the Momentus XT is a HHDD in that it includes a 4GB nand flash SSD integrated with a 500GB (or larger) 7,200 RPM hard disk drive (HDD) in a single 2.5 inch package.

HHDD with integrated nand flash SSD photo courtesy Seagate.com

This is the fifth installment of a series that I have done since June 2010 when I received my first HHDD a Seagate Momentus XT. You can read the other installments of my momentus moments here, here, here and here.

Whats is new with the new generation.
Besides extra storage space capacity up to 750GB (was 500GB), there is twice as much single level cell (SLC) nand flash memory (8GB vs. 4GB in previous generation) along with an enhanced interface using 6Gb per second SATA that supports native command queuing (NCQ) for better performance. Note that NCQ was available on the previous generation Momentus XT that used a 3Gb SATA interface. Other enhancements include a larger block or sector size of 4096 bytes vs. traditional 512 bytes on previous generation storage devices.

This bigger sector size results in less overhead with managing data blocks on large capacity storage devices. Also new are caching enhancements are FAST Factor Flash Management, FAST Factor Boot and Adaptive Memory Technology. Not to be confused with EMC Fully Automated Storage Tiering the other FAST; Seagate FAST is technology that exists inside the storage drive itself. FAST Factor boot enables systems to boot and be productive with speeds similar to SSD or several times faster than traditional HDDs.

The FAST Factor Flash Management provides the integrated intelligence to maximize use of the nand flash or SSD capabilities along with spinning HDD to boot performance, keep up compatibility with different systems and their operating systems. In addition to performance and interoperability, data integrity and SSD flash endurance are also enhanced for investment protection. The Adaptive Memory technology is a self learning algorithm to give SSD like performance for often used applications and data to close the storage capacity too performance gap that has increased along with data center bottlenecks.

Some questions and discussion comments:

When to use SSD vs. HDD vs. HHDD?
If you need the full speed of SSD to boost performance across all data access and cost is not an issue for available capacity that is where you should be focused. However if you are looking for lowest total cost of storage capacity with no need for performance, than lower cost high capacity HDDs should be on your shopping list. On the other hand, if you want a mix of performance and capacity at an effective price, than HHDDs should be considered.

Why the price jump compared to first generation HHDD?
IMHO, it has a lot to do with current market conditions, supply and demand.

With recent floods in Thailand and forecasted HDD and other technology shortages, the lay of supply and demand applies. This means that the supply may be constrained for some products causing demand to rise for others. Your particular vendor or supplier may have inventory however will be less likely to heavily discount while there are shortages or market opportunities to keep prices high. There are already examples of this if you check around on various sites to compare prices now vs. a few months ago. Granted it is the holiday shopping season for both people as well as organizations spending the last of their available budgets so more demand for available supplies.

What kind of performance or productivity have I seen with HHDDs?
While I have not yet tested and compared the second generation or new devices, I can attest to the performance improvements resulting in better productivity over the past year using Seagate Momentus XT HHDDs compared to traditional HDDs. Here is a post that you can follow to see some boot performance comparisons as part of some virtual desktop infrastructure (VDI) sizing testing I did earlier this year that included both HHDD and HDD.

	HHDD desktop 1	HDD desktop 1	HHDD desktop 2
Avg. IOPS	334	69 to 113	186 to 353
Avg. MByte sec	5.36	1.58 to 2.13	2.76 to 5.2
Percent IOPS read	94	80 to 88	92
Percent MBs read	87	63 to 77	84
Mbytes read	530	201 to 245	504
Mbytes written	128	60 to 141	100
Avg. read latency	2.24ms	8.2 to 9.5ms	1.3ms
Avg. write latency	10.41ms	20.5 to 14.96ms	8.6ms
Boot duration	120 seconds	120 to 240 sec	120

When will I jump on the SSD bandwagon?
Great question, I have actually been on the SSD train for several decades using them, selling them, covering, analyzing and consulting around them along with other storage mediums including HDD, HHDD, cloud and tape. I have some SSDs and will eventually put them into my laptops, workstations and servers as primary storage when the opportunity makes sense.

Will HHDDs help backup and other data protection tasks?
Yes, in fact I initially used my Momentus XTs as backup or data protection targets along with for moving large amounts of data between systems faster than what my network could support.

Why not use a SSD?
If you need the performance and can afford the price, go SSD!

On the other hand, if you are looking to add a small 64GB, 128GB or even 256GB SSD while retaining a larger capacity, slower and lower cost HDD, an HHDD should be considered as an option. By using an HHDD instead of both a SSD and HDD, you will cut the need of figuring out how to install both in space constrained laptops, desktop or workstations. In addition, you will cut the need to either manually move data between the different devices or avoid having to acquire software or drivers to do that for you.

How much does the new Seagate Momentus XT HHDD cost?
Manufactures Suggested Retail Price (MSRP) is listed at $245 for a 750GB version.

Does the Momentus XT HHDD need any special drivers, adapters or software?
No, they are plug and play. There is no need for caching or performance acceleration drivers, utilities or other software. Likewise no needs for tiering or data movement tools.

How do you install an HHDD into an existing system?
Similar to installing a new HDD to replace an existing one if you are familiar with that process. If not, it goes like this (or uses your own preferred approach).

Attach a new HHDD to an existing system using a cable
Utilize a disk clone or image tool to make a copy of the existing HDD to HHDD
Note that the system may not be able to be used during the copy, so plan ahead.
After the clone or image copy is made, shutdown system, remove existing HDD and replace it with the HHDD that was connected to the system during the copy (remember to remove the copy cable).
Reboot the system to verify all is well, note that it will take a few reboots before the HHDD will start to learn your data and files along with how they are used.
Regarding your old HDD, save it, put it in a safe place and use it as a disaster recovery (DR) backup. For example if you have a safe deposit box or somewhere else safe, put it there for when you will need it in the future.

Seagate Momentus XT and USB to SATA cable

Can an HHDD fit into an existing slot in a laptop, workstation or server?
Yes. In fact, unlike a HDD and SSD combination, that requires multiple slots or forcing one device to be external, HHDDs like the Momentus XT simply use the space where your current HDD is installed.

How do you move data to it?
Beyond the first installation described above, the HHDD appears as just another local device meaning you can move data to or from it like any other HDD, SSD or CD.

Do you need automated tiering software?
No, not unless you need it for some other reason or if you want to use an HHDD as the lower cost, larger capacity option as a companion to a smaller SSD.

Do I have any of the new or second generation HHDDs?
Not yet, maybe soon and I will do another momentus moment point when that time arrives. For the time being, I will continue to use the first generation Momentus XT HHDDs

Bottom line (for now), If you are considering a large capacity, HDDs check out the HHDDs for an added performance boost including faster boot times as well as accessing other data quicker.

On the other hand if you want an SSD however your budget restricts you to a smaller capacity version, look into how an HHDD can be a viable option for some of your needs.

How to write, publish and promote a book or blog

Have you ever read an article, blog post or a book and said to yourself that you could do that, perhaps even better?

Well, unless you have already done so, what are you waiting for to write a book, blog, article or create some other form of content using different mediums or venues?

The other evening I attended a local Stillwater (Artreach St Croix) event (Publishers Forum) with my wife (karenofarcola.com). Karen is working on getting her first book (fiction for children and young adults) published so she was interested in meeting the different publishers. For me I wanted to learn about the local publishers, hear what they had to say in addition to meeting the purveyor of a local book store (Valley Book Seller) who helped promote the event.

It was interesting listening to the panel made up of a nonprofit publisher (Milkweed Editions), a full service self publishing venue (Beaver Pond Press) and regional publishing house (Tristin Publishing).

Having formally published books (e.g. with traditional publishers (Elseiver and CRC/Taylor Francis), ISBNs, Library of Congress (LOC) registration) along with contributing on other projects, not to mention over a thousand articles, tips, reports, white papers, solution briefs, videos and other content, I often get asked what does it take to write a book, blog or other material.

I also get told by people that they could do a better job to which I ask them then why dont they do something about it vs. simply saying that they could do something better.

Back to the Art Reach St Croix publishers forum event, the attendees were mainly aspiring authors looking to get their first works published. Having already been down the path that many in the room were looking to go (get published) it was interesting to hear the various questions and discussion topics. Some of those questions were about the process of self publishing vs. working with the publisher (large or small) in addition to how much costs or how to get discovered. It was also great to hear the panelist discuss some of the hurdles authors face in getting their books published along with promoting their works.

I learned several years ago before I did my first solo book was a tip that another author told me of the importance of promotion. That is your publisher will help enable, however it is up to you the author to promote your works by creating a platform or means of interacting with different audiences. Consequently it was fun to hear the panelist talk with the authors on the importance of creating a platform including a blog, twitter, Google Plus, facebook, doing articles and appearances to help create awareness. What was fun to watch were the authors who seemed to be more comfortable with creating their works and then waiting for the results to occur as opposed to helping make their work a success.

Anyways, for those who are aspiring to write a book, blog or article, or even for those who are content being arm chair authors or Monday morning quarterbacks, here is a link to a series about how to write a book or blog. The series (how to write a book or blog) can be read over at the VMware communities site that Im contributing for as a vExpert.

Oh, and for you aspiring authors or bloggers wondering about creating and developing a platform, what you are reading here is an example of doing just that. In other words, my platform includes what you are reading here in addition to on my regular blog or other venues including Google Plus (G+), Facebook, LinkedIn and twitter among other venues.

So what are you waiting for, go get your book or blog or article written, published and start promoting it.

Ok, nuff said for now

What am I hearing and seeing while out and about

It has been a busy fall 2011 which started out with VMworld 2011 in Las Vegas just before the labor day weekend.

Scenes from the CXI party (@cxi) at VMworld 2011

Besides activity in support of the launch of my new book Cloud and Virtual Data Storage Networking (CRC Press), I have been busy with various client research, consulting and advisory projects. In addition to Las Vegas for VMworld, out and about travel activities for attending conferences and presenting seminars have included visits in Minneapolis (local), Nijkerk Holland and Denver (in the same week) and Orlando (SNW). Upcoming out and about events are scheduled for Los Angles, Atlanta, Chicago, Seattle and a couple of trips to San Jose area before the brief thanksgiving holiday break.

Changing trains on way to Schiphol to board flight to MSP and then to DEN

Climbing out of Denver on way back to MSP, it was a long yet fun week Evening clouds enroute from DEN to MSP
After Denver back to MSP for a few days before SNW in Orlando

While being out and about I have had the chance to meet and visit with many different people. Here are some questions and comments that I have heard while out and about:

What comes after cloud?
Are there standards for clouds and virtualization?
Should cost savings be the justification for going to cloud, virtual or dynamic environments?
How is big data different than traditional stream and flat file analytics and processing using tools such as SAS (Statistical Analysis Software)?
Is big data only about map reduce and hadoop?
Are clouds any less secure or safe for storage and applications?
Do clouds and virtualization removing complexity and simplify infrastructures?
Are cloud storage services cheaper than buying and managing your own?
Is object based storage a requirement for public or private cloud?
Do solution bundles such as EMC vBlock and NetApp FlexPods reduce complexity?
Why is FCoE taking so long to be adopted and is it dead?
Should cost savings be the basis for deciding to do a VDI or virtualization project?
What is the best benchmark or comparison for making storage decisions?

In addition, there continues to be plenty of cloud confusion, FUD and hype around public, private, hybrid along with AaaS, SaaS, PaaS and IaaS among other XaaS. The myth that virtualization of servers, storage and workstations is only for consolidation continues. However there are more people beginning to see the next wave of life beyond consolidation where the focus expands to flexibility, agility and speed of deployment for non aggregated workloads and applications. Another popular myth that is changing is that data footprint reduction (DFR) is only about dedupe and backup. What is changing is an awareness that DFR spans all types of storage and data from primary to secondary leveraging different techniques including archive, backup modernization, compression, consolidation, data management and dedupe along with thin provisioning among other techniques.

Archiving for email, database and file systems needs to be rescued from being perceived as only for compliance purposes. If you want or need to reduce your data footprint impact (DFR), optimize your storage for performance or capacity, enable backup, BC and DR to be performed faster, achieve Green IT and efficiency objectives, expand your awareness around archiving. While discussing archiving, focus is often on the target or data storage medium such as disk, tape, optical or cloud along with DFR techniques such as compression and dedupe or functionally including ediscovery and WORM. The other aspects of archive that need to be looked at include policies, retention, application and software plugins for Exchange, SQL, Sharepoint, Sybase, Oracle, SAP, VMware and others.

Boot storms continue to be a common theme for apply solid state devices (SSD) in support of virtual desktop inititiaves (VDI). There is however a growing awareness and discussions around shutdown storms, day to day maintenance including virus scans in addition to applications that increase the number of writes. Consequently the discussions around VDI are expanding to include both reads and writes as well as reduced latency for storage and networks.

Some other general observations, thoughts and comments:

Getting into Holland as a visitor is easier than returning to the U.S. as a citizen
Airport security screening is more thorough and professional in Europe than in the U.S.
Hops add latency to beer (when you drink it) and to networks (time delay)
Fast tape drives need disk storage to enable streaming for reads and writes
SSD is keeping HDDs alive, HDDs are keeping tape alive and all there roles are evolving while the technologies continue to evolve.
Hybrid Hard Disk Drives (HHDDs) are gaining in awareness and deployments in workstations as well as laptops.
Confusion exists around what are flat layer 2 networks for LANs and Sans

SNW Fall 2011 revisited and SNIA Emerald program

A couple of weeks ago I traveled down to Orlando Florida for a few days to attend the fall 2011 SNW (Storage Networking World) produced in conjunction by IDG Computerworld and the Storage Networking Industry Association (SNIA).

While at the Orlando event, SNIA executive director Leo Legar asked me how many SNWs I had attended and my responses was on which continent?

My answer was part in fun however also serious as I have been attending SNWs (in addition to other SNIA events) for over ten years in both North and South America as well as in Europe including presenting SNIA tutorials and SNW sessions.

SNW is always good for meeting up with old friends and acquaintances along with meeting new ones including twitter tweeps (hashtag #snwusa #snw2011 @sniacloud @snwusa) and the recent event was no exception. Granted SNW is smaller than it was during its peak in the mid 2000s however it was great to go for a couple of days of meetings, checking out the expo hall and some sessions as well as getting out and about meeting people involved with servers, storage, networking, virtualization, cloud, hardware, software and services.

SNW remains as its name implies (Storage Networking World) an event around networking as in conversations, learning, knowledge exchange, information gathering and meetings not to mention the hands on lab. I found the two days I was there adequate to get the meetings and other activities I had planned, along with time for impromptu meetings. ANother observation was that during the peak of the large mega SNW events, while there were more meetings, they were also much shorter along the lines of speed dating vs. those a couple of weeks ago where there was time to have quality conversations.

Some of the news at the recent SNW event, involved SNIA and their Green Storage Initiative (GSI) announcing the availability of the Emerald program Green IT storage energy metrics that have been in the works for several years. The SNIA Emerald program consists of specifications, taxonomies, metrics and measurements standards to gauge various types of storage power or energy usage to gauge its effectiveness. In other words, yes, Green IT and Green storage are still alive, they just are not as trendy to talk about as they were a few years ago which a shift in focus towards productivity, effective use and supporting growth to help close the green gap and missed IT as well as business opportunities.

Also during the recent SNW event, I did a book signing event sponsored by SNIA. If you have not done so, check out the SNIA Cloud Storage Initiative (CSI) who arranged for several of my new book Cloud and Virtual Data Storage Networking to be given away. Book signings are fun in that I get to meet lots of people and hear what they are doing, encountering, looking for, have done, concerned or excited about. It was handy having SNIA CSI material available at the table as I was signing books and visiting with people to be able to give them information about things such as CDMI not to mention hearing what they were doing or looking for. Note to SNIA, if we do this again, lets make sure to have someone from the CSI at the table to join in the fun and conversations as there were some good ones. Learn more about the activities of the SNIA CSI including their Cloud Data Management Initiative (CDMI) here.

Thanks again to SNIA for arranging the book signing event and for those who were not able to get a copy of my new book before they ran out, my publisher CRC Press Taylor and Francis has arranged a special SNIA and SNW discount code. To take advantage of the SNIA and SNW discount code, go to the CRC Press web site (here) and apply the discount code KVK01 during checkout for catalog item K12375 (ISBN: 9781439851739).

Thanks again to Wayne Adams (@wma01606), Leo Legar and Michael Meleedy among others who arranged for a fantastic fall 2011 SNW event along with everyone who participated in the book signing event and other conversations while in Orlando and to those who were involved virtually via twitter.

The blame game: Does cloud storage result in data loss?

I recently came across a piece by Carl Brooks over at IT Tech News Daily that caught my eye, title was Cloud Storage Often Results in Data Loss. The piece has an effective title (good for search engine: SEO optimization) as it stood out from many others I saw on that particular day.

What caught my eye on Carls piece is that it reads as if the facts based on a quick survey point to clouds resulting in data loss, as opposed to being an opinion that some cloud usage can result in data loss.

My opinion is that if not used properly including ignoring best practices, any form of data storage medium or media could result or be blamed for data loss. For some people they have lost data as a result of using cloud storage services just as other people have lost data or access to information on other storage mediums and solutions. For example, data has been lost on tape, Hard Disk Drives (HDDs), Solid State Devices (SSD), Hybrid HDDs (HHDD), RAID and non RAID, local and remote and even optical based storage systems large and small. In some cases, there have been errors or problems with the medium or media, in other cases storage systems have lost access to, or lost data due to hardware, firmware, software, or configuration including due to human error among other issues.

Technology failure: Not if, rather when and how to decrease impact
Any technology regardless of what it is or who it is from along with its architecture design and implementation can fail. It is not if, rather when and how gracefully along with what safeguards to decrease the impact, in addition to containing or isolating faults differentiates various products or solutions. How they automatically repair and self heal to keep running or support accessibility and maintain data integrity are important as is how those options are used. Granted a failure may not be technology related per say, rather something associated with human intervention, configuration, change management (or lack thereof) along with accidental or intentional activities.

Walking the talk
I have used public cloud storage services for several years including SaaS and AaaS as well as IaaS (See more XaaS here) and knock on wood, have not lost any data yet, loss of access sure, however not data being lost.

I follow my advice and best practices when selecting cloud providers looking for good value, service level agreements (SLAs) and service level objectives (SLOs) over low cost or for free services.

In the several years of using cloud based storage and services there has been some loss of access, however no loss of data. Those service disruptions or loss of access to data and services ranged from a few minutes to a little over an hour. In those scenarios, if I could not have waited for cloud storage to become accessible, I could have accessed a local copy if it were available.

Had a major disruption occurred where it would have been several days before I could gain access to that information, or if it were actually lost, I have a data insurance policy. That data insurance policy is part of my business continuance (BC) and disaster recovery (DR) strategy. My BC and DR strategy is a multi layered approach combining local, offline and offsite as along with online cloud data protection and archiving.

Assuming my cloud storage service could get data back to a given point (RPO) in a given amount of time (RTO), I have some options. One option is to wait for the service or information to become available again assuming a local copy is no longer valid or available. Another option is to start restoration from a master gold copy and then roll forward changes from the cloud services as that information becomes available. In other words, I am using cloud storage as another resource that is for both protecting what is local, as well as complimenting how I locally protect things.

Minimize or cut data loss or loss of access
Anything important should be protected locally and remotely meaning leveraging cloud and a master or gold backup copy.

To cut the cost of protecting information, I also leverage archives, which mean not all data gets protected the same. Important data is protected more often reducing RPO exposure and speed up RTO during restoration. Other data that is not as important is protected, however on a different frequency with other retention cycles, in other words, tiered data protection. By implementing tiered data protection, best practices, and various technologies including data footprint reduction (DFR) such as archive, compression, dedupe in addition to local disk to disk (D2D), disk to disk to cloud (D2D2C), along with routine copies to offline media (removable HDDs or RHDDs) that go offsite, Im able to stretch my data protection budget further. Not only is my data protection budget stretched further, I have more options to speed up RTO and better detail for recovery and enhanced RPOs.

If you are looking to avoid losing data, or loss of access, it is a simple equation in no particular order:

Strategy and design
Best practices and processes
Various technologies
Quality products
Robust service delivery
Configuration and implementation
SLO and SLA management metrics
People skill set and knowledge
Usage guidelines or terms of service (ToS)

Unfortunately, clouds like other technologies or solutions get a bad reputation or blamed when something goes wrong. Sometimes it is the technology or service that fails, other times it is a combination of errors that resulted in loss of access or lost data. With clouds as has been the case with other storage mediums and systems in the past, when something goes wrong and if it has been hyped, chances are it will become a target for blame or finger pointing vs. determining what went wrong so that it does not occur again. For example cloud storage has been hyped as easy to use, don’t worry, just put your data there, you can get out of the business of managing storage as the cloud will do that magically for you behind the scenes.

The reality is that while cloud storage solutions can offload functions, someone is still responsible for making decisions on its usage and configuration that impact availability. What separates various providers is their ability to design in best practices, isolate and contain faults quickly, have resiliency integrated as part of a solution along with various SLAs aligned to what the service level you are expecting in an easy to use manner.

Does that mean the more you pay the more reliable and resilient a solution should be?
No, not necessarily, as there can still be risks including how the solution is used.

Does that mean low cost or for free solutions have the most risk?
No, not necessarily as it comes down to how you use or design around those options. In other words, while cloud storage services remove or mask complexity, it still comes down to how you are going to use a given service.

Shared responsibility for cloud (and non cloud) storage data protection
Anything important enough that you cannot afford to lose, or have quick access to should be protected in different locations and on various mediums. In other words, balance your risk. Cloud storage service provider toned to take responsibility to meet service expectations for a given SLA and SLOs that you agree to pay for (unless free).

As the customer you have the responsibility of following best practices supplied by the service provider including reading the ToS. Part of the responsibility as a customer or consumer is to understand what are the ToS, SLA and SLOs for a given level of service that you are using. As a customer or consumer, this means doing your homework to be ready as a smart educated buyer or consumer of cloud storage services.

If you are a vendor or value added reseller (VAR), your opportunity is to help customers with the acquisition process to make informed decision. For VARs and solution providers, this can mean up selling customers to a higher level of service by making them aware of the risk and reward benefits as opposed to focus on cost. After all, if a order taker at McDonalds can ask Would you like to super size your order, why cant you as a vendor or solution provider also have a value oriented up sell message.

Poll: Who is responsible for cloud storage data loss?

Taking action, what you should (or not) do
Dont be scared of clouds, however do your homework, be ready, look before you leap and follow best practices. Look into the service level agreements (SLAs) associated with a given cloud storage product or service. Follow best practices about how you or someone else will protect what data is put into the cloud.

For critical data or information, consider having a copy of that data in the cloud as well as at or in another place, which could be in a different cloud or local or offsite and offline. Keep in mind the theme for critical information and data is not if, rather when so what can be done to decrease the risk or impact of something happening, in other words, be ready.

Data put into the cloud can be lost, or, loss of access to it can occur for some amount of time just as happens with using non cloud storage such as tape, disk or ssd. What impacts or minimizes your risk of using traditional local or remote as well as cloud storage are the best practices, how configured, protected, secured and managed. Another consideration is the type and quality of the storage product or cloud service can have a big impact. Sure, a quality product or service can fail; however, you can also design and configure to decrease those impacts.

Wrap up
Bottom line, do not be scared of cloud storage, however be ready, do your homework, review best practices, understand benefits and caveats, risk and reward. For those who want to learn more about cloud storage (public, private and hybrid) along with data protection, data management, data footprint reduction among other related topics and best practices, I happen to know of some good resources.

Trick or treat: 2011 IT Zombie technology poll

Warning: Do not be scared, however be ready for some trick and treat fun, it is after all, the Halloween season.

I like new emerging technologies and trends along with Zombie technologies, you know, those technologies that have been declared dead yet are still being enhanced, sold and used.

Zombie technologies as a name may be new for some, while others will have a realization of experiencing something from the past, technologies being declared deceased yet still alive and being used. Zombie technologies are those that have been declared dead, yet still alive enabling productivity for customers that use them and often profits for the vendors who sell them.

Zombie technologies

Some people consider a technology or trend dead once it hits the peak of hype as that can signal a time to jump to the next bandwagon or shiny new technology (or toy).

Others will see a technology as being dead when it is on the down slope of the hype curve towards the trough of disillusionment citing that as enough cause for being deceased.

Yet others will declare something dead while it matures working its way through the trough of disillusionment evolving from market adoption to customer deployment eventually onto the plateau of productivity (or profitability).

Then there are those who see something as being dead once it finally is retired from productive use, or profitable for sale.

Of course then there are those who just like to call anything new or other than what they like or that is outside of their comfort zone as being dead. In other words, if your focus or area of interest is tied to new products, technology trends and their promotion, rest assured you better be where the resources are being applied and view other things as being dead and thus probably not a fan of Zombie technologies (or at least publicly).

On the other hand, if your area of focus is on leveraging technologies and products in a productive way, including selling things that are profitable without a lot of marketing effort, your view of what is dead or not will be different. For example if you are risk averse letting someone else be on the leading bleeding edge (unless you have a dual redundant HA blood bank attached to your environment) your view of what is dead or not will be much different from those promoting the newest trend.

Funny thing about being declared dead, often it is not the technology, implementation, research and development or customer acquisitions, rather simply a lack of promotion, marketing and general awareness. Take tape for example which has been a multi decade member of the Zombie technology list. Recently vendors banded together investing or spending on marketing awareness reaching out to say tape is alive. Guess what, lo and behold, there was a flurry of tape activity in venues that normally might not be talking about tape. Funny how marketing resources can bring something back from the dead including Zombie technologies to become popular or cool to discuss again.

With the 2011 Halloween season among us, it is time to take a look this years list of Zombie technologies. Keep in mind that being named a Zombie technology is actually an honor in that it usually means someone wants to see it dead so that his or her preferred product or technology can take it place.

Here are 2011 Zombie technologies.

Backup: Far from being dead, its focus is changing and evolving with a broader emphasis on data protection. While many technologies associated with backup have been declared dead along with some backup software tools, the reality is that it is time or modernizes how backups and data protection are performed. Thus, backup is on the Zombie technology list and will live on, like it or not until it is exorcised from, your environment replaced with a modern resilient and flexible protected data infrastructure.

Big Data: While not declared dead yet, it will be soon by some creative marketer trying to come up with something new. On the other hand, there are those who have done big data analytics across different Zombie platforms for decades which of course is a badge of honor. As for some of the other newer or shiny technologies, they will have to wait to join the big data Zombies.

Cloud: Granted clouds are still on the hype cycle, some argue that it has reached its peak in terms of hype and now heading down into the trough of disillusionment, which of course some see as meaning dead. In my opinion cloud, hype has or is close to peaking, real work is occurring which means a gradual shift from industry adoption to customer deployment. Put a different way, clouds will be on the Zombie technology list of a couple of decades or more. Also, keep in mind that being on the Zombie technology list is an honor indicating shift towards adoption and less on promotion or awareness fan fare.

Data centers: With the advent of the cloud, data centers or habitats for technology have been declared dead, yet there is continued activity in expanding or building new ones all the time. Even the cloud relies on data centers for housing the physical resources including servers, storage, networks and other components that make up a Green and Virtual Data Center or Cloud environment. Needless to day, data centers will stay on the zombie list for some time.

Disk Drives: Hard disk drives (HDD) have been declared dead for many years and more recently due to popularity of SSDs have lost their sex appeal. Ironically, if tape is dead at the hands of HDDs, then how can HDDs be dead, unless of course they are on the Zombie technology list. What is happening is like tape, HDDs role are changing as the technology continues to evolve and will be around for another decade or so.

Fibre Channel (FC): This is a perennial favorite having been declared dead on a consistent basis over three decades now going back to the early 90s. While there are challengers as there have been in the past, FC is far from dead as a technology with 16 Gb (16GFC) now rolling out and a transition path for Fibre Channel over Ethernet (FCoE). My take is that FC will be on the zombie list for several more years until finally retired.

Fibre Channel over Ethernet (FCoE): This is a new entrant and one uniquely qualified for being declared dead as it is still in its infancy. Like its peer FC which was also declared dead a couple of decades ago, FCoE is just getting started and looks to be on the Zombie list for a couple of decades into the future.

Green IT: I have heard that Green IT is dead, after all, it was hyped before the cloud era which has been declared dead by some, yet there remains a Green gap or disconnect between messaging and issues thus missed opportunities. For a dead trend, SNIA recently released their Emerald program which consists of various metrics and measurements (remember, zombies like metrics to munch on) for gauging energy effectiveness for data storage. The hype cycle of Green IT and Green storage may be dead, however Green IT in the context of a shift in focus to increased productivity using the same or less energy is underway. Thus Green IT and Green storage are on the Zombie list.

iPhone: With the advent of Droid and other smart phones, I have heard iPhones declared dead, granted some older versions are. However while the Apple cofounder Steve Jobs has passed on (RIP), I suspect we will be seeing and hearing more about the iPhone for a few years more if not longer.

IBM Mainframe: When it comes to information technology (IT), the king of the Zombie list is the venerable IBM mainframe aka zSeries. The IBM mainframe has been declared dead for over 30 years if not longer and will be on the zombie list for another decade or so. After all, IBM keeps investing in the technology as people buy them not to mention IBM built a new factory to assemble them in.

NAS: Congratulations to Network Attached Storage (NAS) including Network File System (NFS) and Windows Common Internet File System (CIFS) aka Samba or SMB for making the Zombie technology list. This means of course that NAS in general is no longer considered an upstart or immature technology; rather it is being used and enhanced in many different directions.

PC: The personal computer was touted as killing off some of its Zombie technology list members including the IBM mainframe. With the advent of tablets, smart phones, virtual desktops infrastructures (VDI), the PC has been declared dead. My take is that while the IBM mainframe may eventually drop of the Zombie list in another decade or two if it finds something to do in retirement, the PC will be on the list for many years to come. Granted, the PC could live on even longer in the form of a virtual server where the majority of guest virtual machines (VMs) are in support of Windows based PC systems.

Printers: How long have we heard that printers are dead? The day that printers are dead is the day that the HP board of directors should really consider selling off that division.

RAID: Its been over twenty years since the first RAID white paper and early products appeared. Back in the 90s RAID was a popular buzzword and bandwagon topic however, people have moved on to new things. RAID has been on the Zombie technology list for several years now while it continues to find itself being deployed at the high end of the market down into consumer products. The technology continues to evolve in both hardware as well as software implementations on a local and distributed basis. Look for RAID to be on the Zombie list for at least the next couple of decades while it continues to evolve, after all, there is still room for RAID 7, RAID 8, RAID 9 not to mention moving into hexadecimal or double digit variants.

SAN: Storage Area Networks (SANs) have been declared dead and thus on the Zombie technology list before, and will be mentioned again well into the next decade. While the various technologies will continue to evolve, networking your servers to storage will also expand into different directions.

tape summit resources: Magnetic tape has been on the Zombie technology list almost as long as the IBM mainframe and it is hard to predict which one will last longer. My opinion is that tape will outlast the IBM mainframe, as it will be needed to retrieve the instructions on how to de install those Zombie monsters. Tape has seen resurgence in vendors spending some marketing resources and to no surprise, there has been an increase in coverage about it being alive, even at Google. Rest assured, tape is very safe on the Zombie technology list for another decade or more.

Windows: Similar to the PC, Microsoft Windows has been touted in the past as causing other platforms to be dead, however has been added to the Zombie list for many years now. Given that Windows is the most commonly virtualized platform or guest VM, I think we will be hearing about Windows on the Zombie list for a few decades more. There are particular versions of Windows as with any technology that have gone into maintenance or sustainment mode or even discontinued.

Poll: What are the most popular Zombie technologies?

Keep in mind that a Zombie technology is one that is still in use, being developed or enhanced, sold usually at a profit and used typically in a productive way. In some cases, a declared dead or Zombie technology may only be just in its infancy getting started having either just climbed over the peak of hype or coming out of the trough of disillusionment. In other instance, the Zombie technology has been around for a long time yet continues to be used (or abused).

Note: Zombie voting rules apply which means vote early, vote often, and of course vote for those who cannot include those that are dead (real or virtual).

Ok, nuff said, enough fun, lets get back to work, at least for now

Trick or treat: Have you seen any IT Frankenstacks

Given that it is Halloween season, time for some fun.

Over the past couple of weeks various product and solution services announcements have been made that result in various articles, columns, blogs and commentary in support of them.

Ever wonder which if any of those products could actually be stitched together to work in a production environment without increasing the overall cost and complexity that they sometimes promote as their individual value proposition? Granted, many can and do work quite well when introduced into heterogeneous or existing environments with good interoperability. However what about those that look good on paper or in a webex or you tube video on their own, however may be challenged to be pieced together to work with others?

Reading product announcements

Hence in the spirit of halloween, the vision of a Frankenstack appeared.

A Frankenstack is a fictional environment where you piece various technologies from announcements or what you see or hear about in different venues into a solution.

Part of being a Frankenstack is that the various pieces may look interesting on their own, good luck trying to put them together on paper let alone in a real environment.

While I have not yet attempted to piece together any Frankenstacks lately, I can visualize various ones.

Stacking or combining different technologies, will they work together?

A Frankenstack could be based on what a vendor, VAR, or solution provider proposes or talks about.

A Frankenstack could also also be what a analyst, blogger, consultant, editor, pundit or writer pieces together in a story or recommendation.

Some Frankenstacks may be more synergistic and interoperable than others perhaps even working in a real customer environment.

Of course even if the pieces could be deployed, would you be able to afford them let alone support them (interoperability aside) without adding complexity?

You see a Frankenstack might look good on paper or on a slide deck, webex or via some other venue, however will it actually work or apply to your environment or are they just fun to talk about?

Dont get me wrong, I like hearing about new technology and products as much as anyone else, however lets have some fun with Frankenstacks and keep in perspective do they help or add complexity to your environment.

Ok, enough fun for now, let me know what you see or can put together in terms of Frankenstacks.

Keep in mind they dont actually have to work as that is what qualifies them for trick or treat and Frankenstack status.

Enjoy your Halloween season, do not be afraid, however be ready for some tricks and treats, its that time of the year.

Convergence: People, Processes, Policies and Products

Converged and dynamic infrastructures, cloud and virtual environments are popular themes and industry trends with different levels of adoption and deployment occurring. Although are you focusing on products, or the other Ps, that is people, processes and policies (or more here).

The reason I bring this up is quite often I hear discussions that are centered around the products (or services) providing various benefits, return on investment or cost saving opportunities.

Very little discussions are heard around whats being done or enabled by vendors and service providers, or what is being adopted by customers to tie in people, process and policy convergence.

Industry Trend: Removing organizational barriers to enable convergence technology

Put another way, the discussions focus around the new technology or service while forgetting or assuming that the people, process and policies will naturally fall into place.

Will customer policies, process or procedures along with internal organizational (e.g. politics) issues with how people leverage those converged products also evolve?

I assert that while there are benefits that can be obtained from leveraging new enabling technologies (hardware, software, networks, services) their full potential will not be realized until policies, process, people skill sets and even more important, organizational or intradepartmental turf wars and boundaries are also addressed.

Converged family team

This does not mean consolidating different groups, rather it can mean thawing out relations between groups if there are challenges, establishing an abstraction or virtual layer, a virtual team to cut across different technology domains combing various skill sets, new best practices, policies and procedures in order to streamline management of physical and virtual resources.

Chuck Hollis (aka twitter @ChuckHollis) of EMC has an interesting blog post (here) that ties in the themes of different IT groups working or not having situational awareness that is worth a read. You can also read this Industry Trends and Perspective solution brief that I did earlier this year on the topic of Removing Organizational Barriers for Leveraging Technology Convergence.

Here are some additional related posts:

What is your organization doing (or have done) to enable convergence factoring in people, processes, policies and products or is it a non issue for you?

Cloud and Virtual Data Storage Networking book released

Ok, it’s now official, following its debut at the VMworld 2011 book store last week in Las Vegas, my new book Cloud and Virtual Data Storage Networking (CRC Press) is now formally released with general availability announced today along with companion material located at https://storageioblog.com/book3 including the Cloud and Virtual Data Storage Networking LinkedIn group page launched a few months ago. Cloud and Virtual Data Storage Networking (CVDSN) a 370 page hard cover print is my third solo book that follows The Green and Virtual Data Center (CRC Press 2009) and Resilient Storage Networks (Elsevier 2004).

Cloud and Virtual Data Storage Networking Book by Greg Schulz
CVDSN book was on display at VMworld 2011 book store last week along with a new book by Duncan Epping (aka @DuncanYB ) and Frank Denneman (aka @frankdenneman ) titled VMware vSphere 5 Clustering Technical Deepdive. You can get your copy of Duncan and Franks new book on Amazon here.

Here is a photo of me on the left visiting a VMworld 2011 attendee in the VMworld book store.

Whats inside the book, theme and topics covered

When it comes to clouds, virtualization, converged and dynamic infrastructures Dont be scared however do look before you leap to be be prepared including doing your homework.

What this means is that you should do your homework, prepare, learn, and get involved with proof of concepts (POCs) and training to build the momentum and success to continue an ongoing IT journey. Identify where clouds, virtualization and data storage networking technologies and techniques compliment and enable your journey to efficient, effective and productive optimized IT services delivery.

There is no such thing as a data or information recession: Do more with what you have

A common challenge in many organizations is exploding data growth along with associated management tasks and constraints, including budgets, staffing, time, physical facilities, floor space, and power and cooling. IT clouds and dynamic infrastructure environments enable flexible, efficient and optimized, cost-effective and productive services delivery. The amount of data being generated, processed, and stored continues to grow, a trend that does not appear to be changing in the future. Even during the recent economic crisis, there has been no slow down or information recession. Instead, the need to process, move, and store data has only increased, in fact both people and data are living longer. CVDSN presents options, technologies, best practices and strategies for enabling IT organizations looking to do more with what they have while supporting growth along with new services without compromising on cost or QoS delivery (see figure below).

Driving Return on Innovation the new ROI: Doing more, reducing costs while boosting productivity

Expanding focus from efficiency and optimization to effectiveness and productivity

A primary tenant of a cloud and virtualized environment is to support growing demand in a cost-effective manner with increased agility without compromising QoS. By removing complexity and enabling agility, information services can be delivered in a timely manner to meet changing business needs.

There are many types of information services delivery model options

Various types of information services delivery modes should be combined to meet various needs and requirements. These complimentary service delivery options and descriptive terms include cloud, virtual and data storage network enabled environments. These include dynamic Infrastructure, Public & Private and Hybrid Cloud, abstracted, multi-tenant, capacity on demand, Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS) among others.

Convergence combing different technology domains and skill sets

Components of a cloud and virtual environment include desktop, servers, and storage, networking, hardware, and software, services along with APIs and software stacks. This include virtual and physical desktops, data, voice and storage networks, LANs, SANs, MANs, WANs, faster blade and rack servers with more memory, SSD and high-capacity storage and associated virtualization tools and management software. True convergence combines leveraging technology and people, processes and best practices aligned to make the most of those resources to deliver cost-effective services delivery.

Best people, processes, practices and products (the four Ps)

Bringing all the various components together is the Ps (people skill sets, process, practices and products). This means leveraging and enhancing people skill sets and experience, process and procedures to optimize workflow for streamlined service orchestration, practices and policies to be more effectively reducing waste without causing new bottlenecks, and products such as racks, stacks, hardware, software, and managed or cloud services.

Service categories and catalogs, templates SLO and SLA alignment

Establishing service categories aligned to known service levels and costs enables resources to be aligned to applicable SLO and SLA requirements. Leveraging service templates and defined policies can enable automation and rapid provisioning of resources including self-service requests.

Navigating to effective IT services delivery: Metrics, measurements and E2E management

You cannot effectively manage what you do not know about; likewise, without situational awareness or navigation tools, you are flying blind. E2E (End to End) tools can provide monitoring and usage metrics for reporting and accounting, including enabling comparison with other environments. Metrics include customer service satisfaction, SLO and SLAs, QoS, performance, availability and costs to service delivered.

The importance of data protection for virtual, cloud and physical environments

Clouds and virtualization are important tools and technologies for protecting existing consolidated or converged as well as traditional environments. Likewise, virtual and cloud environments or data placed there also need to be protected. Now is the time to rethink and modernize your data protection strategy to be more effective, protecting, preserving and serving more data for longer periods of time with less complexity and cost.

Packing smart and effectively for your journey: Data footprint reduction (DFR)

Reducing your data footprint impact leveraging data footprint reduction (DFR) techniques, technologies and best practices is important for enabling an optimized, efficient and effective IT services delivery environment. Reducing your data footprint is enabled with clouds and virtualization providing a means and mechanism for archiving inactive data and for transparently moving it. On the other hand, moving to a cloud and virtualized environment to do more with what you have is enhanced by reducing the impact of your data footprint. The ABCDs of data footprint reduction include Archiving, Backup modernization, Compression and consolidation, Data management and dedupe along with Storage tiering and thin provisioning among other techniques.

Industry Veteran Greg Schulz of StorageIO Reveals Latest IT Strategies in “Cloud and Virtual Data Storage Networking” Book
StorageIO Founder Launches the Definitive Book for Enabling Cloud, Virtualized, Dynamic, and Converged Infrastructures
