Blog Roll Déjà Vu and Storage Monkeys

Ever have blog roll Déjà Vu? If not, go visit various blogs and look at the blog rolls.

While some blog owners do a good job of keeping their blog rolls up to date (for example the Storage Monkeys site) given their interests, preferences or blog objectives, there are also many who appear to simply cut and paste blog rolls from other sites (Not the Storage Monkeys).

Ok, fair enough keeping up with the Jones or whoever the neighbors or rivals are. However it’s also interesting to note how someone may not have taken the time to actually check out what is being cut and pasted from one list to another to see if still relevant or even active.

Hmm, Déjà Vu, kind of like how did a teacher know who was copying who’s homework in school? Let’s leave the copying content discussion for another blog post as that’s another topic altogether.

Spotting this pattern of blog roll cut and paste Déjà Vu late last year, I did a little research and analysis (you may recall, that’s something that analysts are supposed to do ;) ) pointing to a couple of trends.

One trend I saw was that many of those links were either stale, or, the sites they ended up at were stale or had changed to something else, hmm, linking to what others are doing yet not actually following, thus blog rolls keeping up with the Jones. For example vendor to vendor for smash / trash talk discussions or debates. Yet another trend found was that many of the blog rolls were dated as their sites were created for example early on in the blog era, then as the enthusiasm faded or something new appeared, the sites go stale.

I also found that some bloggers/web sites actively update and manage their blog rolls while others seem to take the approach that more is better (kind of like twitter thinking, more followers, more tweets are better?) e.g. qty vs. quality for example seeing some blog rolls that should have a vertical scroll bar or requiring some dedupe processing.

I used to have an extensive blog roll when I put up my blog about two years ago of which the first six months or so I let the blog site lay in stealth, low key mode as I watched, learned and figured out how, when and where I would leverage the blog and where/what I wanted to accomplished with it. Hmm, there’s that analytic stuff coming back again ;).

Now in fairness, want to see some links? Go to my links pages here and here or the portfolio page or checkout twitter (backtweets or other venues), read through some of my blog posts which are filled with links to other sites, venues and more.

As for my blog, I used to have a more extensive blog roll, however I’m currently under the mind set that fewer maybe better, that is unless you are a follower and simply want to show/post what others are doing to be part of the crowd.

What does all of this mean if anything and what’s my point?

Simple!

My hat off to Storage Monkeys, a site that if you are not yet a member, take a few minutes and go register, it’s not a vendor sponsored or endorsed site, nor is it an analyst or media sponsored site, rather, it’s a site put up and supported by folks who are involved in technology as a means for peers to collaborate.

Thus it’s not a vendor centric site, not a var centric site, not an engineering centric site, not a site loaded up with product ads or pitches, not a want to be media site, rather, simply what’s on the mind of the community that is made up of IT pros, vars, vendors, analyst’s media and others.

Congratulations to the Storage Monkeys who did two recent polls or votes to update their blog rolls. One blog roll for vendors was open to public polling/balloting and has lead to controversy given the results. The other poll for non-vendors was open to any registered Storage monkey and while it appears that the membership base grew during the polling with little to no controversy.

One of the things I noticed about the monkeys poll is that given its diverse membership base, some of the names you might expect to see on the poll list were absent, that is, those that might have a stronger vendor following than IT pros. Likewise, some of those on the list that might fare better in a vendor poll, fared different!

What might this mean? Vendors tend to like those who tell them or you what they want to hear or what they want told. IT pros for the most part I find tend to prefer to hear it as it is, sometimes bad news is good news and so forth.

I’m proud to have been named for the first time to the Storage Monkeys non-vendor blog roll having landed in the #5 spot particularly as I view this as a poll of peers (IT folks, vendors/vars, media or other analysts) who are registered as Storage Monkeys.

Congratulations to Curtis Preston (aka Mr. Backup and Dr. Dedupe) for moving up in the polls and landing in the #1 spot, likewise, let’s hear it for Chris M. Evans (aka Storage Architect) who moved up from the #10 to #2 spot in the polls. There also was some changing of the guard so to speak with three others joining me in the top ten who had not been there before.

Summer Book Update and Back to School Reading

August and thus Summer 2009 in the northern hemisphere are swiftly passing by and start of a new school year is just around the corner which means it is also time for final vacations, time at the beach, pool, golf course, amusement park or favorite fishing hole among other past times. In order to help get you ready for fall (or late summer) book shopping for those with IT interests, here are some Amazon lists (here, here and here) for ideas, after all, the 2009 holiday season is not that far away!

Here’s a link to my Amazon.com Authors page that includes coverage of both my books, "The Green and Virtual Data Center" (CRC) and "Resilient Storage Networks – Designing Scalable Flexible Data Infrastructures" (Elsevier).

The Green and Virtual Data Center (CRC)Resilient Storage Networks - Designing Flexible Scalable Data Infrastructures (Elsevier)

Click here to look inside "The Green and Virtual Data Center" (CRC) and or inside "Resilient Storage Networks" (Elsevier).

Its been six months since the launch announcement of my new book "The Green and Virtual Data Center" (CRC) and general availability at Amazon.com and other global venues here and here. In celebration of the six month anniversary of the book launch (thank you very much to all who have bought a copy!), here is some coverage including what is being said, related articles, interviews, book reviews and more.

Article: New Green Data Center: shifting from avoidance to becoming more efficient IT-World August 2009

wsradio.com interview discussing themes and topics covered in the book including closing the green gap and shifting towards an IT efficiency and productivity for business sustainability.

Closing the green gap: Discussion about expanding data centers with environmental benefits at SearchDataCenter.com

From Greg Brunton – EDS/An HP Company: “Greg Schulz has presented a concise and visionary perspective on the Green issues, He has cut through the hype and highlighted where to start and what the options are. A great place to start your green journey and a useful handbook to have as the journey continues.”

From Rick Bauer – Storage Networking Industry Association (SNIA) – Education and Technology Director”
“Greg is one of the smartest “good guys” in the storage industry.
He has been a voice of calm amid all the “green IT hype” over the past few years. So when he speaks of the possible improvements that Green Tech can bring, it’s a much more realistic approach…”

From CMG (Computer Measurement Group) MeasureIT
I must admit that I have been slightly skeptical at times, when it comes to what the true value is behind all of the discussions on “green” technologies in the data center. As someone who has seen both the end user and vendor side of things, I think my skepticism gets heightened more than it normally would be. This book really helped dispel my skepticism.

The book is extremely well organized and easy to follow. Each chapter has a very good introduction and comprehensive summary. This book could easily serve as a blueprint for organizations to follow when they look for ideas on how to design new data centers. It’s a great addition to an IT Bookshelf. – Reviewed by Stephen R. Guendert, PhD (Brocade and CMG MeasureIT). Click here to read the full review in CMG MeasureIT.

From Tom Becchetti – IT Architect: “This book is packed full of information. From ecological and energy efficiencies, to virtualization strategies and what the future may hold for many of the key enabling technologies. Greg’s writing style benefits both technologists and management levels.”

From MSP Business Journal: Greg Schulz named an Eco-Tech Warrior – April 2009

From David Marshall at VMblog.com: If you follow me on Linked in, you might have seen that I had been reading a new book that came out at the beginning of the year titled, “The Green and Virtual Data Center” by Greg Schulz. Rather than writing about a specific virtualization platform and how to get it up and running, Schulz takes an interesting approach at stepping back and looking at the big picture. After reading the book, I reached out to the author to ask him a few more questions and to share his thoughts with readers of VMBlog.com. I know I’m not Oprah’s Book Club, but I think everyone here will enjoy this book. Click here to read more what David Marshal has to say.

    Green IT Confusion Continues, Opportunities Missed!

    I continue to see those looking for fast silver bullets in the quest to be green, efficient, optimized or sustainable while addressing issues ranging from power/energy, cooling, floor-space/footprint, EH&S (environmental health & safety) not to mention recycling. Yet, I’m also continued to be  amazed by the focus and emphasis around reduce as in reduce your capacity and your performance or processing capabilities in the form of consolidation or aggregation along with energy avoidance which for some is applicable.

    However, there is also the other side of the tale which is shifting from avoidance to becoming more efficient, that is doing more with what you have or with less while boosting productivity. For example, having a server or processor that can do more work in the same or smaller physical footprint drawing the same or less energy and requiring less cooling is a form of reducing overall impact yet boosting productivity. The same can be done with data and I/O networks, storage and even software.

    Similar to automobiles after the 1970s oil and energy crisis, the focus was on reduction, conservation and avoidance as the form of being efficient. Over time, this approach gave way to levering more efficient engines and vehicles that boosted the MPG city and highway, change in driving or usage habits, awareness of issues including applicable metrics and energy costs, as well as the continuing quest for alternative fuels.

    This is no different than what is happening with the IT organizations or compute focused entities in that there has been an initial focus of avoidance to meet short term tactical requirements, not to mention all of the green hype of a few years ago. Today there is a shift taking place towards efficiency and awareness that optimization and efficiency is more than consolidation, that it also includes boosting productivity as part of achieving reduced energy and cooling demands.

    How this can be done is to leverage multiple different techniques including new servers with processors that have intelligent power management (IPM) also known as adaptive voltage scaling (AVS) or other marketing terms enabling variable performance and energy consumption. For example, vary clock cycles and turn on cores when needed, then to turn off cores, slow clock speed down when there is less work to be done. Likewise there are improvements with cooling closer to the heat source ranging from leveraging inert liquid cooling inside the cabinet of computers to surface attached cooling to emerging micro cooling located inside silicon. There is a fascination with using virtualization to consolidate and reduce servers that are underutilized, which again is applicable for some environments and applications.

    However not all servers including many that are underutilized lend themselves to being consolidated for various reasons including quality of service (QoS) or performance, security, vendor support or software compatibility, politics or finance among others. This however does not mean that they cannot be virtualized, it more than likely mean that they cannot be consolidated. There is a common myth that virtualization equals consolidation and vice versa, however virtualization can also be used for abstraction, transparency, emulation and enabling agility including support for load-balancing, scale-up and scale-out performance oriented clustering among other uses. Thus there is another side of virtualization and that is to achieve   efficiency, life beyond consolidation.

    Needless to say there are many more technologies and techniques to address various issues now along with those that are emerging. The good news in all of this is the growing awareness that there are many different faces or facets of being green. That green wash and green hype may be on the endangered species list, that green means more than reducing carbon footprints or recycling or energy avoidance. That green is really about shifting and becoming more efficient, more optimized to support more processing, more work in a cost effective manner to sustain growth on a go forward basis. For high performance compute (HPC) or other large scale IT organizations, there is a notion that small improvements on a large broad scale have significant impact.

    Some organizations are in pursuit of technologies of solutions that promise significant saving ratios over small sets or instances, solutions that provide  smaller reduction or savings over a larger basis can prove to be more effective. For example, if power is a concern, powering down servers or storage that promises 85-100% savings might only be applicable to less than 5% of the devices. However, if 85-100% of the devices can be upgraded to newer models that boost productivity by 5-15% (or more) in the same or smaller footprint, using 5-15% (or more) less power, the results add up quickly. Think of it this way, a 1% saving for an environment using 1,000 kilo watt hour (kWh) or 1mWh of energy is a savings of 10kWh. The point being that for large environments, don’t forget to look at small savings that apply to a large installed base that then add up to big benefits.

    The net result is that one can pursue being green or being perceived as being green which can have a high cost, or, can pursue various efficiency that help the overall organization by boosting productivity, helping the top and bottom line, doing more in a smaller footprint and guess what, the result is not only economic, it’s also environmental positive. Thus, the byproduct of shifting towards efficiency (and not just avoidance) is to become green!

    Mirror mirror on the wall, who’s the greenest of them all?

    If you subscribe to the notion that Green IT is all about carbon footprints, you may be missing out on some real opportunities to go green. After all, carbon is part of the green movement, there are many other aspects including supply chain, efficiency, sustainability in addition to recycling, not to mention optimizing power, cooling footprints in order to do more work in a productive manner.

    So who is the greenest of them all? Could it be Brocade, CA, Cisco, EMC, Hitachi, IBM, Intel, LSI, Microsoft, NetApp, Oracle, Symantec, VMware or 3PAR? What about the cloud crowd or perhaps one of the industry trade groups such as Green grid, SNIA GSI, Climate Savers Computing or Carbon disclosure project perhaps among others?

    You might be surprised, now granted, this list is for consumer products. However, given their broad adoption, and looking at Green as more than carbon impact, and with the EPA implanting Energy Star for Servers and now Energy Star for storage in the works, not to mention factoring in the green supply chain, have a look here.

    Here’s an interesting read about how the Internet is causing global warming. How ironic, given Al Gore’s carbon crusade, and the folk-lore claim about  (or mistaken have claimed) to have invented the Internet, no wonder he has been able to cash-in and transform Green to Gold.

    For those interested in saving money with efficient and optimized storage (e.g. the new Green) to boost productivity, here’s an article to check out.

    Ok, that’s enough "Green" fun for now.

    Cheers gs

    Clarifying Clustered Storage Confusion

    Clustered storage can be iSCSI, Fibre Channel block based or NAS (NFS or CIFS or proprietary file system) file system based. Clustered storage can also be found in virtual tape library (VTL) including dedupe solutions along with other storage solutions such as those for archiving, cloud, medical or other specialized grids among others.

    Recently in the IT and data storage specific industry, there has been a flurry of merger and acquisition (M&A) (Here and here), new product enhancement or announcement activity around clustered storage. For example, HP buying clustered file system vendor IBRIX complimenting their previous acquisition of another clustered file system vendor (PolyServe) a few years ago, or, of iSCSI block clustered storage software vendor LeftHand earlier this year. Another recent acquisition is that of LSI buying clustered NAS vendor ONstor, not to mention Dell buying iSCSI block clustered storage vendor EqualLogic about a year and half ago, not to mention other vendor acquisitions or announcements involving storage and clustering.

    Where the confusion enters into play is the term cluster which means many things to different people, and even more so when clustered storage is combined with NAS or file based storage. For example, clustered NAS may infer a clustered file system when in reality a solution may only be multiple NAS filers, NAS heads, controllers or storage processors configured for availability or failover.

    What this means is that a NFS or CIFS file system may only be active on one node at a time, however in the event of a failover, the file system shifts from one NAS hardware device (e.g. NAS head or filer) to another. On the other hand, a clustered file system enables a NFS or CIFS or other file system to be active on multiple nodes (e.g. NAS heads, controllers, etc.) concurrently. The concurrent access may be for small random reads and writes for example supporting a popular website or file serving application, or, it may be for parallel reads or writes to a large sequential file.

    Clustered storage is no longer exclusive to the confines of high-performance sequential and parallel scientific computing or ultra large environments. Small files and I/O (read or write), including meta-data information, are also being supported by a new generation of multipurpose, flexible, clustered storage solutions that can be tailored to support different applications workloads.

    There are many different types of clustered and bulk storage systems. Clustered storage solutions may be block (iSCSI or Fibre Channel), NAS or file serving, virtual tape library (VTL), or archiving and object-or content-addressable storage. Clustered storage in general is similar to using clustered servers, providing scale beyond the limits of a single traditional system—scale for performance, scale for availability, and scale for capacity and to enable growth in a modular fashion, adding performance and intelligence capabilities along with capacity.

    For smaller environments, clustered storage enables modular pay-as-you-grow capabilities to address specific performance or capacity needs. For larger environments, clustered storage enables growth beyond the limits of a single storage system to meet performance, capacity, or availability needs.

    Applications that lend themselves to clustered and bulk storage solutions include:

    • Unstructured data files, including spreadsheets, PDFs, slide decks, and other documents
    • Email systems, including Microsoft Exchange Personal (.PST) files stored on file servers
    • Users’ home directories and online file storage for documents and multimedia
    • Web-based managed service providers for online data storage, backup, and restore
    • Rich media data delivery, hosting, and social networking Internet sites
    • Media and entertainment creation, including animation rendering and post processing
    • High-performance databases such as Oracle with NFS direct I/O
    • Financial services and telecommunications, transportation, logistics, and manufacturing
    • Project-oriented development, simulation, and energy exploration
    • Low-cost, high-performance caching for transient and look-up or reference data
    • Real-time performance including fraud detection and electronic surveillance
    • Life sciences, chemical research, and computer-aided design

    Clustered storage solutions go beyond meeting the basic requirements of supporting large sequential parallel or concurrent file access. Clustered storage systems can also support random access of small files for highly concurrent online and other applications. Scalable and flexible clustered file servers that leverage commonly deployed servers, networking, and storage technologies are well suited for new and emerging applications, including bulk storage of online unstructured data, cloud services, and multimedia, where extreme scaling of performance (IOPS or bandwidth), low latency, storage capacity, and flexibility at a low cost are needed.

    The bandwidth-intensive and parallel-access performance characteristics associated with clustered storage are generally known; what is not so commonly known is the breakthrough to support small and random IOPS associated with database, email, general-purpose file serving, home directories, and meta-data look-up (Figure 1). Note that a clustered storage system, and in particular, a clustered NAS may or may not include a clustered file system.

    More nodes, ports, memory, and disks do not guarantee more performance for applications. Performance depends on how those resources are deployed and how the storage management software enables those resources to avoid bottlenecks. For some clustered NAS and storage systems, more nodes are required to compensate for overhead or performance congestion when processing diverse application workloads. Other things to consider include support for industry-standard interfaces, protocols, and technologies.

    Scalable and flexible clustered file server and storage systems provide the potential to leverage the inherent processing capabilities of constantly improving underlying hardware platforms. For example, software-based clustered storage systems that do not rely on proprietary hardware can be deployed on industry-standard high-density servers and blade centers and utilizes third-party internal or external storage.

    Clustered storage is no longer exclusive to niche applications or scientific and high-performance computing environments. Organizations of all sizes can benefit from ultra scalable, flexible, clustered NAS storage that supports application performance needs from small random I/O to meta-data lookup and large-stream sequential I/O that scales with stability to grow with business and application needs.

    Additional considerations for clustered NAS storage solutions include the following.

    • Can memory, processors, and I/O devices be varied to meet application needs?
    • Is there support for large file systems supporting many small files as well as large files?
    • What is the performance for small random IOPS and bandwidth for large sequential I/O?
    • How is performance enabled across different application in the same cluster instance?
    • Are I/O requests, including meta-data look-up, funneled through a single node?
    • How does a solution scale as the number of nodes and storage devices is increased?
    • How disruptive and time-consuming is adding new or replacing existing storage?
    • Is proprietary hardware needed, or can industry-standard servers and storage be used?
    • What data management features, including load balancing and data protection, exists?
    • What storage interface can be used: SAS, SATA, iSCSI, or Fibre Channel?
    • What types of storage devices are supported: SSD, SAS, Fibre Channel, or SATA disks?

    As with most storage systems, it is not the total number of hard disk drives (HDDs), the quantity and speed of tiered-access I/O connectivity, the types and speeds of the processors, or even the amount of cache memory that determines performance. The performance differentiator is how a manufacturer combines the various components to create a solution that delivers a given level of performance with lower power consumption.

    To avoid performance surprises, be leery of performance claims based solely on speed and quantity of HDDs or the speed and number of ports, processors and memory. How the resources are deployed and how the storage management software enables those resources to avoid bottlenecks are more important. For some clustered NAS and storage systems, more nodes are required to compensate for overhead or performance congestion.

    Worried about IT M&A, here come the new startups!

    Storage I/O trends

    Late last year , I did a post (see here) countering the notion that there is a lack of innovation in IT and specifically around data storage. Recently I did a post about a Funeral for Friend, not to mention yesterdays post about Summer marriages.

    For those who are concerned about lack of innovation, or, that consolidation will result in just a few big vendors, here’s some food for thought. Those big vendors in addition to growing via internal organic growth, also grow by buying or merging with other vendors. Those other vendors emerge as startups, some grow, blossom and are bought, some make a decent business on their own, some are looking to be bought, some need to be bought, some will see fire sales, liquidation or simply closing their doors and perhaps re-launching as a new company.

    With all the M&A activity currently that has taken place, and I’m sure (speculation only ;) ) that there will be plenty more, here’s a short and far from comprehensive list of some startups or companies you may not have heard of yet. There are additional ones who are still in deep stealth, some on the list are still in stealth, yet talking and letting information trickle out, thus only non-NDA information is being shown here. In other words, you can find out about these via publicly available information and sources.

    Something that I have noticed and talked with others in the industry about is that this generation of startups, at least for now are taking a far more low-key approach to their launches than in the past. Gone at least for now are the Dot COM era over the top announcements in some cases before there was even a product or shipping for actual customer production deployment scenario. This crop or corps of startups are taking their time leveraging the current economic situation to further incubate their technologies and go to market strategies, not to mention minimizing the amount of over the top VC funding we have seen in the past. Some of these may not appear to be storage related and that would be correct. This list includes those associated with data infrastructure technolgies from servers, to storage to networking, hardware, software and services among othes as a common theme.

    Disclosure Notice: None of these companies mentioned are nor have ever been clients of StorageIO. Why do I mention this, why not!

    Summer Weddings: EMC+Datadomain and HP+IBRIX

    Storage I/O trends

    Are you friend or family of the bride or groom?

    Here’s comes the bride! (Audio)

    That’s a question me and Mrs. Schulz were asked recently when we attended a wedding.

    Summer months particularly June and August are known as wedding months (Hmmm, more merger & acquisition activity to come?). Summer is a nice time of the year for marriages at least in the U.S. and how ironic that we have already seen two well publicized IT data storage industry unions in the past couple of weeks, not to mention other smaller less publicized ones.

    In one case, the California based bride (Datadomain-DDUP) had two courtiers (Massachusetts based EMC and California based NetApp, plus rumors of others). Fortunately one of those had a prenuptial that earned them a cool $57 million for their efforts (NetApp-NTAP) when EMC won the bride. Read more including some of my comments and perspectives among others about EMC, NTAP and DDUP here and here.

    Yesterday, on a mid-July Friday, when things are normally quiet, in true wedding industry forum, news was released (here and here) that California based HP announced that it had bought Massachusetts based data and storage management software vendor IBRIX.

    That’s a lot of activity involving California and Massachusetts in the past couple of weeks, not to mention the tornado sightings in the vicinity of EMCs Hopington Massachusetts headquarters coincidently around the same time the marriage to DDUP was formerly announced! What’s’ next, Aerosmith is out on tour, perhaps the Del Fuegos or Boston will perform at one of these wedding parties?

    Within the data storage industry, publicly traded Datadomain (DDUP) is fairly well known to many for their role in helping to popularize the data footprint impact reduction technique refereed to as de-duplication (e.g. normalization, commonality factoring, intelligent compression, etc.). Adding to the awareness of DDUP was the recent highly public courtship with EMC eventually out-bidding NTAP with a dowry of about $2.1B USD. That type of press coverage and monetary amounts might normally be expected for the likes of a Madonna, Brittney Spears, Michael Jackson-RIP, Paris Hilton, Elizabeth Taylor or other celebrity unions covered by paparazzi with a similar number of attorneys involved.

    On the other hand, IBRIX while known to some, is a lessor known entity compared to DDUP having taken a lower profile than even some of their close competitors. However for those who have been following and covering the clustered storage market (see here, here, here, here, here, here, here, here and here ), IBRIX is a well known entity.

    IBRIX also has had ties to EMC having been involved in a pre-mari age affair with an reseller arrangement along with being "rumored" ;) to have been involved with ATMOS cloud or policy based storage solution formerly known as "Hulk". IBRIX has also quietly been involved with others like Dell as well as HP in similar to EMC reseller arrangements. Where IBRIX has been positioned is to address high performance, scale out parallel or concurrent clustered file system needs, both big and small I/O, sequential and random data storage and access. For example, in the media/entertainment and other industries along with enabling large Internet providers a bulk (low cost, high capacity) scale-out NAS (NFS & CIFS) option.

    One of the reasons that IBRIX has been involved with the likes of EMC, Dell and HP among others is that unlike other vendors such as BlueArc, the once high-flying Isilon, NetApp, Onstor or Panasas, not to mention EMC Cellera NAS , is that those solutions are all bundled with proprietary hardware while IBRIX is software based. Where IBRIX Fusion fits is to enable NAS storage solutions using industry standard hardware (servers and storage) that are capable of being configured for both high performance compute (HPC) along with for low-cost general purpose bulk storage to support Web 2.0, social networking, home directories or on-line archives.

    Consequently, and HP or Dell who just happen to sell servers, have had the ability of meeting large scale out and scale up NAS file serving applications by re-selling IBRIX installed on their servers or blade servers with either their own entry to mid-range lower cost, high performance and high capacity storage along with that of 3rd party vendors.

    Ironically one of IBRIX’s competitors in the software NAS solution market was and remains PolyServe, software that HP acquired a couple of years ago to create their own scale out NAS solution (e.g. EFS). Other software based solutions include among others Lustre (Sun), CXFS (SGI), EMC ATMOS (I’m sure some will argue this is not scale out or NAS, will leave it at that for now) ;) not to mention those from IBM, Microsoft, Quantum (also re-sold by HP) or Symantec.

    What does HP get with IBRIX?

    Simple, the ability to own the IP (intellectual proprietary) that one of their competitors had been "rumored" to have been working with at one point, IP that their competitors had been reselling like themselves.

    Thus HP gets more software IP that can and has been sold along with their hardware such as the Proliant servers and blade servers giving their customers choice, similar to what HP and other vendors do with their open servers. For example, HP had the ExDS9000 extreme storage system built on a blade server with high density, low cost, high capacity HP storage (e.g. HP Modular Disk System 600, HP MSA or even EVA).

    This makes for a nice solution for bulk on-line and near-line storage applications where the emphasis is not as much on performance, rather massive scalability for storing on-line documents, archives, videos, images and other unstructured content which is where there is a lot of growth activity. The challenge is that the ExDS9x00 has only been available with the HP PolyServe software which works good for some environments, yet, for others, the clustered file system scale out capabilities of IBRIX were deployed.

    With the addition of IBRIX, HP now should be able to provide their customers and prospects the choice of software to meet specific needs while maintaining an HP footprint, that is both hardware, software and services. HP has several different storage software stacks that they now own (e.g. Lefthand for clustered iSCSI, PolyServe for NFS/CIFS NAS, IBRIX for Clustered File system scale out NAS) not to mention those that it OEMS including among others Bycast (Medical Archive System) that is also OEM’d by IBM as their Medical Grid combined with IBM SOFS, Quantum StorNext and Microsoft Windows Storage Server and Sepaton (VTL and Dedupe) to name a few.

    Do I think this was a good move by HP?

    Yes as it gives them control over IP that they had been reselling as had some of their competitors who left IBRIX to HP to grab up. HP now has the IP which they can package with their hardware similar to how they have been doing, and giving customers choices to align the right hardware and software technology to the task at hand.

    Whether it be Bycast for medical archiving, PolyServe or IBRIX for scale out NAS, Lefthand for clustered iSCSI, Sepaton for VTL and dedupe, Microsoft, Quantum StorNext for shared block storage serving or any of the other software packages HP offers with their industry standard servers, the customer has options.

    For IBRIX customers and prospects, this move will give them a boost in a confidence that their decisions and investments are safe.

    Ironically, vendors like Symantec with their Scaleable File Serving (SFS) clustered NAS solution that is also software based and runs on anyone’s open servers including those from HP gets a potential shot in the arm with HP validating the model and approach for bulk-storage and clustered NAS (Oh Mr. Salem, Mr. Dell is holding on Line 1, Mr. Chambers is on line 2 and Mr. Ellison on line 3 ;) )

    Who’s going to be at the alter next? IMHO, I would keep an eye on (and this all just pure speculation) Bycast, Symantec, EMLX (Broadcom was a wake up call), Quantum, Sepaton, STEC, StorMagic, or ACS, maybe even 3PAR among other possibilities (think outside of the lines). I would not rule out a major game changer such as someone buying NetApp or the likes of an HP buying an EMC or Oracle buying a CSC, maybe even a CSCO buying someone like NTAP, how about Oracle buying NTAP and putting some attorneys out of work, not to mention, who will MSFT hook up with? Anything is possible as we have seen and traditional M&A wisdom is out the window.

    Have fun at the next wedding you attend, go easy on the cake and wedding punch, especially if you will be doing any dancing (please, no You tube videos of the chicken dance) and be careful throwing rice or other items.

    Ok, nuff said.

    SPC and Storage Benchmarking Games

    Storage I/O trends

    There is a post over in one of the LinkedIn Discussion forums about storage performance council (SPC) benchmarks being miss-leading that I just did a short response post to. Here’s the full post as LinkedIn has a short post response limit.

    While the SPC is far from perfect, it is at least for block, arguably better than doing nothing.

    For the most part, SPC has become a de facto standard for at least block storage benchmarks independent of using IOmeter or other tools or vendor specific simulations, similar how MSFT ESRP is for exchange, TPC for database, SPEC for NFS and so forth. In fact, SPC even recently rather quietly rolled out a new set of what could be considered the basis for Green storage benchmarks. I would argue that SPC results in themselves are not misleading, particularly if you take the time to look at both the executive and full disclosures and look beyond the summary.

    Some vendors have taken advantage of the SPC results playing games with discounting on prices (something that’s allowed under SPC rules) to show and make apples to oranges comparisons on cost per IOP or other ploys. This proactive is nothing new to the IT industry or other industries for that matter, hence benchmark games.

    Where the misleading SPC issue can come into play is for those who simply look at what a vendor is claiming and not looking at the rest of the story, or taking the time to look at the results and making apples to apples, instead of believing the apples to oranges comparison. After all, the results are there for a reason. That reason is for those really interested to dig in and sift through the material, granted not everyone wants to do that.

    For example, some vendors can show a highly discounted list price to get a better IOP per cost on an apple to oranges basis, however, when processes are normalized, the results can be quite different. However here’s the real gem for those who dig into the SPC results, including looking at the configurations and that is that latency under workload is also reported.

    The reason that latency is a gem is that generally speaking, latency does not lie.

    What this means is that if vendor A doubles the amount of cache, doubles the number of controllers, doubles the number of disk drives, plays games with actual storage utilization (ASU), utilizes fast interfaces from 10 GbE  iSCSI to 8Gb FC or FCoE or SAS to get a better cost per IOP number with discounting, look at the latency numbers. There have been some recent examples of this where vendor A has a better cost per IOP while achieving a higher number of IOPS at a lower cost compared to vendor B, which is what is typically reported in a press release or news story. (See a blog entry that also points to a CMG presentation discussion around this topic here.

    Then go and look at the two results, vendor B may be at list price while vendor A is severely discounted which is not a bad thing, as that is then the starting list price as to which customers should start negotiations. However to be fair, normalize the pricing for fun, look at how much more equipment vendor A may need while having to discount to get the price to offset the increased amount of hardware, then look at latency.

    In some of the recent record reported results, the latency results are actually better for a vendor B than for a vendor A and why does latency matter? Beyond showing what a controller can actually do in terms of levering  the number of disks, cache, interface ports and so forth, the big kicker is for those talking about SSD (RAM or FLASH) in that SSD generally is about latency. To fully effectively utilize SSD which is a low latency device, you would want a controller that can do a decent job at handling IOPS; however you also need a controller that can do a decent job of handling IOPS with low latency under heavy workload conditions.

    Thus the SPC again while far from perfect, at least for a thumb nail sketch and comparison is not necessarily misleading, more often than not it’s how the results are utilized that is misleading. Now in the quest for the SPC administrators to try and gain more members and broader industry participation and thus secure their own future, is the SPC organization or administration opening itself up to being used more and more as a marketing tool in ways that potentially compromise all the credibility (I know, some will dispute the validity of SPC, however that’s reserved for a different discussion ;) )?

    There is a bit of Déjà here for those involved with RAID and storage who recall how the RAID Advisory Board (RAB) in its quest to gain broader industry adoption and support succumbed to marketing pressures and use or what some would describe as miss-use and is now a member of the “Where are they now” club!

    Don’t get me wrong here; I like the SPC tests/results/format, there is a lot of good information in the SPC. The various vendor folks who work very hard behind the scenes to make the SPC actually work and continue to evolve it also all deserve a great big kudos, an “atta boy” or “atta girl” for the fine work that have been doing, work that I hope does not become lost in the quest to gain market adoption for the SPC.

    Ok, so then this should all then beg the question of what is the best benchmark. Simple, the one that most closely resembles your actual applications, workload, conditions, configuration and environment.

    Ok, nuff said.

    Green Storage is Alive and Well: ENERGY STAR Enterprise Storage Stakeholder Meeting Details

    While Green hype and green washing may be on the endangered species list if not already extinct, there are many things taking place to shift the focus from talking about being green to enabling and leveraging efficiency and optimization to boost productivity and enable business sustainability.

    The industry has seen and is seeing the shift from the initial green hype cycle of a few years ago to the more recent trough of disillusionment (or here) typically found with a post technology or trend hangover, to the current re-emergence, and growing awareness of the many different faces and facets of being green.

    Granted there has been some recent activity by the U.S. government to add new climate control legislation (e.g. HR2454 – Waxman/Markey) to build on previous clean air acts of the 1990s as well as those dating back to the 1970s and earlier.

    While the green gap (or here) still exists with confusion by IT organizations that Green is only Green if and only if it is about reducing Carbon footprints as opposed to the realization that there are many different faces or facets of being Green and efficient. For example, there is also a growing awareness that addressing power, cooling, floor-space or footprint to enable sustained business growth as well as enabling next generation virtual, cloud as well as traditional forms of IT service ennablement has both economic and business benefits. That is, determining energy usage, shifting from energy avoidance to expanding and supporting energy efficiency initiatives along with boosting productivity, doing more with what you have, fitting into and growing within current or future constraints on available power, cooling, footprint/floorpsace, budget or manpower constraints while improving on service delivery to remain competitive. (Learn more in "The Green and Virtual Data Center" (CRC) )
    The Green and Virtual Data Center Book

    Regardless of if you are a eco-tech warrior or not, learning about and then closing the Green gap and how shifting a focus towards efficiency has both business economic and environmental benefits and helps to break down some of the perceptions about what Green is or is not.

    One such activity is the U.S. EPA Energy Star program which is about as much energy avoidance as it is about energy efficiency You might be familiar with Energy Star logos on various consumer products around your home or office as well as for laptops, notebooks, desktop and workstations. Recently EPA released a new standard specification for Energy Star for Servers and is now currently working on one for enterprise storage. As part of the initiative, stakeholders or those with an interest in data storage are invited to participate in upcoming EPA working sessions to provide feedback and input on what is important to you.

    Spring is not supposed to be a time for send offs, after all, its supposed to be the time when things come to life or refresh from winter sleep or hibernation such plants, flowers, trees, grass, spring animals, fishing opening after spawning not to mention spring weddings. With the passing this week of Ed McMahon, Farah Fawcett and Michael Jackson, you might think that’s the funeral for a friend I’m referring.

    While I have fond memories of Ed McMahon as Johnny Carson’s side kick on the tonight show, that’s not the funeral for a friend.

    Likewise, who can forget Farah Fawcett and her poster, even though we share something in common, that is she died in the same hospital that I was born in, that’s not the funeral I’m referring to.

    Neither is the passing of Michael Jackson that is not only flooding the media, its also testing and taxing many web sites and data infrastructures (here, and here among others), that’s not the funeral for a friend I’m referring to either.

    Now I do not know anyone who has succumbed to the N1H1 (swine flue) virus yet, and while people have died from it, so far it seems like some IT technologies (insert your favorite or non-favorite technology here), everyone is talking about it, however who actually has it, so that’s not the funeral I’m referring to.

    Nor is the Elton John song from Yellow Brick Road what I’m referring to.

    No, the funeral for a friend that I’m referring to is a different one all together, its the funeral for the magnetic hard disk drive (e.g. disk drive or HDD) that we have come to know and rely upon, in some cases for some people, they don’t even know that they have been relying on a HDD in their PC or computer or notebook. For some, they think that the HDD is just memory (actually it is), or in their TiVo or DVR, or the magic resource in the cloud, internet, web hosting or managed service site where different files and data can be stored and backed-up to. Yes, it was a sad funeral as many go however the HDD was not alone at the funeral, as many of its contemporaries were also being eulogized including Green IT, Fibre Channel, the IBM mainframe, Microsoft Windows, magnetic tape, printers, RAID, IT data centers, physical copper networking wiring and the combustion engine to name a few others.

    What do these all have in common and why was there a funeral? Becuase they have been declared as being dead by someone, or perhaps wished that they were dead by others! Like them or not, we rely on them all, they become a friend, a friend that sometimes you get along with, and at times that you are at odds with, however a friend never the less. Thus it was impressive to see the large virtual crowd in attendance for this funeral or wake, after all, most in attendance, including the deceased were scratching their heads (even the disks – some of you will get the humor ;) ) as after all, non of the deceased are actually dead.

    Does that mean if they are not dead, yet supposed to be dead that they are ghosts or zombies? It turns out the afore mentioned are examples of what I commonly refer to as Zombie technologies in that they have been declared dead by pundits or marketers trying to prop up something new, yet the technologies continue to be enhanced and sold by vendors often with little to no fanfare as IT customers will buy, deploy use and rely on these technologies.

    Granted, in some cases the technologies may not be the current best friend or industry darling, however there is a dependence on these and other technologies.

    I mean think about it, RAID is dead so new raid or dist. Parity or something else can take RAIDs place (I attended the RAID sendoff recently). Or that the HDD is dead so that the market can switch over to FLASH SSD, another recent send-off. Or that tape is dead at the hands of dedupe, that was lasts weeks send off, or the mainframe, Fibre Channel and so forth. In some cases, some could not attend their own funeral as they were to busy supporting all of the demands of more data to move, process and store including the bloggers, twitters, texters, friend feeders and so forth.

    One of the interesting things about going to these send offs is meeting up with old friends and acquaintances to hear what they are doing these days, for example, in addition to some people, I ran into the mainframe who is still busy working. I saw and talked to the mini-server who has been busy hosting VMware and Microsoft HyperV consolidation that also showed me photos of its new blades.

    Fibre Channel was looking robust and energized excited about its upcoming new role combined with Ethernet as FCoE. The disk drive had hoped to be retired by now however, while some of the high performance Fibre Channel variants might fade away with 2.5" high performance SAS HDDs picking up that slack while SSD continues to mature and evolve, not to mention even larger capacity HDDs picking up more work, the HDD see’s that it will be working for at least another decade as there is just too much work to be done in an economical mannor to retire to some day isle (you know, that place that you say some day Isle go there)… In fact the HDDs were telling me about how they have to be ready to be deployed in hosting, managed services as well as cloud sites when those finally ramp-up on large scale basis beyond today’s web and infrastructure hosting providers.

    Some of the zombies told me how they are working with new peer technologies or have been repackaged and new marketing campaigners as part of their awareness tour, similar to promoters bring aging rock stars back out on highly productive and profitable tours for their fans while helping to promote the new material.

    During one of these recent sendoffs, I was pondering this and all of a sudden it dawned on me and a bright light bulb went on that drew enough watts to make a high-end server or storage system look efficient. The emergence of the new technology hype was causing all of these send-offs. Here’s what I came up with by doing some quick analysis on the back of one of the funerals during a long winded eulogy that was further out there than a 12MByte 55 slide deck complete with ramifications during a 15-30 minute product launch WebEx, Goto Meeting or other session.

    Having had the revelation, I decided to do some analysis, you know, the thing that analysts are supposed to such as thinking outside the box, looking at different trends, issues, spotting patterns, coming up with different perspectives some of which may be outside the box or not mainstream, sometimes taking a view that is contrarian or skeptical, applying that gray matter between the ears (not the gray hair)…

    In the quest to launch new products, perhaps due to a lack of innovative marketing to promote innovative and evolutionary technologies, the trend is to simply declare something else dead so the new technology can replace it which had me wondering is if its not the technology that’s dead, rather, has creative marketing died? Recently the HDD or disk drive has once again been declared dead (as has magnetic tape and others) as it has been many times over the past 50 plus years of existence, after all, it can be a bit of a sport or make for easy game to jump up and declare something dead as after all, with technology there always has to be something new to talk about.

    The reality is that many IT organizations are risk averse, the are creatures of habits, they use and leverage what they know, what they trust and in some cases regardless of if they like the technology or not, thus, the importance of bridging the gap between the past, what works, what is known and field proven including the good, the bad and the ugly aspects as transitions are made to new technology and techniques. The trick is not clinging to the past with a death grip while ignoring the future, or likewise, jumping in with both feet to the new techniques and technology, after all, many environments are risk averse so the only way leading bleeding edge approaches are taken is if there is a dual redundant blood bank located next door (that some more IT HA humor ; ) )

    Here’s my point, contrary to renewed focus that the disk drive is dead at the hands of solid state disk (SSD) and FLASH in particular, I’m not clinging to the past as I have been and remain a fan of SSD for about 20 years. However also seeing the reality, and not choosing to simply jump on yet another SSD bandwagon movement, it is safe to say that the HDD in various shapes and forms will be around for at least another decade. Likewise, magnetic tape which has been declared dead for I don’t know how many decades also continues to be enhanced and deployed and thus not dead. In fact, when I talk with IT folks around the world and ask them if they care to admit to using tape, its fun to watch them look around the room to see who is going to catch them raise their hands, then sure enough, when comfortable, 65-75% of the hands go up.

    Now to be fare, many of these same organizations are using some form of disk based backup and data protection in conjunction with repositioning (here, here, here, and here among others) tape for ultra-low cost, ultra energy efficient (e.g. green) storage. Changing usage of tape include for long term data retention including archive, full backup that were staged first to disk as well as compliance among other purposes.

    Thus the notion of tiered storage, that is leveraging the most applicable technology aligned to the task at hand to meet service and cost requirements while balancing performance, availability, capacity and energy efficiency in a flexible manor comes to mind, after all, there is no such thing as a data recession!

    Does this mean that new technologies including de-dupe, thin-provisioning, clusters, grids, clouds, SaaS, Soa, object based, virtualization, SSD and many others are not being deployed? They are in fact being deployed alongside in many cases with the so called zombie or dead technologies in what some might think of as a mentoring program of sorts. That is bridging the past to the future, case in point being virtual tape libraries (VTLs see also here, and here among others) that make disk look like tape to fool existing backup and data protection software, processes and procedures while leveraging new techniques including space saving snapshots, staging data to disk as a cache or buffer before streaming to tape, using data footprint techniques including compression and de-dupe among others.

    Now remembering some actual deceased from the technology world, various IT firms, technologies, and individuals no longer with us, some who gave their all to help propel the industry to get it to where it is today and still evolving including TCAM, Storage Service Providers (SSP), RAID Advisory Board (RAB), Token Ring, Briton Lee Database machine (DejaVu anyone?), Imperial Technologies (An SSD vendor), SF2 (Bought by MTI, Patents bought by EMC), Pirus (Bought by Sun and then discontinued), DEC (Bought by Compaq and then by HP), DG (Bought by EMC), Wang (Getronics), Openvision (Bought by Veritas, bought by Symantec), Memorex (Brand bought by Imation), Next, and Osborne not to mention influences such as Ray Norda, Grace Hopper, Thomas Watson, Blaze Pascal, Seymor Cray and Al Shugart among many many others, RIP.

    Now to the technology zombies including among others Backup, Data Centers, Ethernet, Facebook, Fibre Channel, IT Professionals, Landline Telecommunications, Mainframe, Magnetic Hard Disk Drives, Magnetic Tape, Microsoft Office, Microsoft Windows, non-clustered storage, Personal Computers and Desktops, Printers, RAID, Twitter, Unix to name a few. RIP, continue working, evolving, prospering, helping those who rely on you or continue to invest in you and remember, that in your passing, you are not only laying the ground work for the future, you are the bridge between the old and the new that allows those who rely upon you to continue doing what they need to do while your eventual successors continue to incubate, emerge, mature and evolve leveraging you are a mentor and peer.

    Don’t feel bad if one of the technologies that you use and rely on has been declared dead, instead, celebrate and have a wake of sorts, in fact, get the sales or marketing person who is telling you that your technology is dead to pay for the cost of the wake as part of their admission into becoming part of your technology family and future IT data infrastructure After all, even virtual and cloud environments still rely on many of these so called dead technologies to keep their costs of service down, while keeping their availably and performance up, is that ironic or what!

    In the meantime, for the actual deceased, RIP Ed, Farah, Michael and all of the others, and for those technology zombies not quite ready to lay to rest yet, best wishes and stay in touch!

    Nuf said for now.

    Introducing US HR2454 – Waxman-Markey Climate Bill

    US HR2454 – Waxman-Markey Climate Bill

    In case you have not heard yet…

    On a related note to a recent post pertaining to energy efficiency vs. energy avoidance and common perception that Green IT is all about carbon footprints (e.g. the Green Gap), here’s some material for those who like to read or talk about carbon and emissions trading schemes (ETS). Currently in the US congress, there is legislation making the rounds generically called the Waxman-Markey Climate Change bill or also known as HR2454 e.g. American Clean Energy and Security Act (coverage here, here, here and here among others). This is the latest version at a clean energy and climate bill and its effects or impacts on IT or business is yet to be clear, other than a presumed tax increase of some form such as a surcharge or fee tacked onto your energy bill as is the case today with other environmental or compliance initiatives.

    Given the amount of energy used by the aviation industry, an industry that is far more likely to be impacted by ETS or other initiatives than IT (at least initially), its been interesting to watch what’s been going on in the aviation world for the past couple of years now with regards to climate and environmental concerns. Now without being an alarmist, or claiming an inconvient truth, for background and insight, here’s a link to a recent piece (Emissions Trading Could Be Inevitable) from AWST to put some things into perspective on caps, trade and related ETS topics on a global basis perhaps shedding some light on what could impact other industries and their supply chains.

    Ok, nuff said.

    Shifting from energy avoidance to energy efficiency

    Storage I/O trends

    I’m continually amazed at the number of people in the IT industry from customers to vendors, vars to media and even analysts who associate Green IT with and only with reducing carbon footprints. I guess I should not be surprised given the amount of rhetoric around Green and carbon both in the IT industry as well as in general resulting in a Green Gap.

    The reality as I have discussed in the past is that Green IT while addressing carbon footprint topics, is really more about efficiency and optimization for business economic benefits that also help the environment. From a near-term tactical perspective, Green IT is about boosting productivity and enabling business sustainability during tough economic times, doing more with less, or, doing more with what you have. On a strategic basis, Green IT is about continued sustainability while also improving top and bottom line economics and repositioning IT as a competitive advantage resource.

    There is a lot of focus on energy avoidance, as it is relatively easy to understand and it is also easy to implement. Turning off the lights, turning off devices when they are not in use, enabling low-power, energy-savings or Energy Star® (now implemented for servers with storage being a new focus) modes are all means to saving or reducing energy consumption, emissions, and energy bills.

    Ideal candidates for powering down when not in use or inactive include desktop workstations, PCs, laptops, and associated video monitors and printers. Turning lights off or implementing motion detectors to turn lights off automatically, along with powering off or enabling energy-saving modes on general-purpose and consumer products has a significant benefit. New generations of processors such as the Intel Xeon 5xxx or 7xxx series (formerly known as Nehalem) provide the ability to boost performance when needed, or, go into various energy conservation modes when possible to balance performance, availability and energy needs to applicable service requirements, a form of intelligent power management.

    In Figure 1 are shown four basic approaches (in addition to doing nothing) to energy efficiency. One approach is to avoid energy usage, similar to following a rationing model, but this approach will affect the amount of work that can be accomplished. Another approach is to do more work using the same amount of energy, boosting energy efficiency, or the complement—do the same work using less energy.

    Tiered Storage
    Figure 1 the Many Faces of Energy Efficiency (Source: “The Green and Virtual Data Center” (CRC)

    The energy efficiency gap is the difference between the amount of work accomplished or information stored in a given footprint and the energy consumed. In other words, the bigger the energy efficiency gap, the better, as seen in the fourth scenario, doing more work or storing more information in a smaller footprint using less energy.

    Given the shared nature of their use along with various intersystem dependencies, not all data center resources can be powered off completely. Some forms of storage devices can be powered off when they are not in use, such as offline storage devices or mediums for backups and archiving. Technologies such as magnetic tape or removable hard disk drives that do not need power when they are not in use can be used for storing inactive and dormant data.

    Avoiding energy use can be part of an approach to address power, cooling, floor space and environmental (PCFE) challenges, particularly for servers, storage, and networks that do not need to be used or accessible at all times. However, not all applications, data or workloads can be consolidated, or, powered down due to performance, availability, capacity, security, compatibility, politics, financial and many other reasons. For those applications that cannot be consolidated, the trick is to support them in a more efficient and effective means.

    Simply put, when work needs to be done or information needs to be stored or retrieved or data moved, it should be done so in the most energy-efficient manner aligned to a given level of service which can mean leveraging faster, higher performing resources (servers, storage and networks) to get the job done fast resulting in improved productivity and efficiency.

    Tiering is an approach that applies to servers, storage, and networks as well as data protection. For example, tiered servers include large frame or mainframes, rack mount as well as blades with various amounts of memory, I/O or expansion slots and number of processor cores at different speeds. Tiered storage includes different types of mediums and storage system architectures such as those shown in figure 2. Tiered networking or tiered access includes 10Gb and 1Gb Ethernet, 2/4/8 Gb Fibre Channel, Fibre Channel over Ethernet (FCoE), iSCSI, NAS and shared SAS among others. Tiered data protection includes various technologies to meet various recovery time objectives (RTO) and recovery point objectives (RPO) such as real-time synchronous mirroring with snapshots, to periodic backup to disk or tape among other approaches, techniques and technologies.

    Technology alignment (Figure 2), that is aligning the applicable type of storage or server resource and devices to the task at hand to meet application service requirements is essential to archiving an optimized and efficient IT environment. For example, for very I/O intensive active data as shown in figure 2, leveraging ultra fast tier-0 high-performance SSD (FLASH or RAM) storage, or for high I/O active data, tier-1 fast 15.5K SAS and Fibre Channel storage based systems would be applicable.

    For active and on-line data, that’s where energy efficiency in the form of fast disk drives including RAM SSD or FLASH SSD (for reads, writes are another story) and in particular fast 15.5K or 10K FC and SAS energy efficient disks and their associated storage systems come into play. The focus for active data and storage systems should be around more useful work per unit of energy consumed in a given footprint. For example, more IOPS per watt, more transactions per watt, more bandwidth or video streams per watt, more files or emails processed per watt.

    Tiered Storage

    Figure 2 Tiered Storage: Balancing Performance, Availability, Capacity and Energy to QoS (Source: “The Green and Virtual Data Center” (CRC)

    For low-performance, low activity applications where the focus is around storing as much data as possible with the lowest cost including for disk to disk based backup, slower high capacity SATA based storage systems are the fit (lower right in figure 2). For long-term bulk storage to meet archiving, data retention or other retention needs as well as storing large monthly full backups or long term data preservation, tape remains the ticket for large environments with the best combination of performance, availability capacity and energy efficiency and cost per footprint.

    General approaches to boost energy efficiency include:

    • Do more work using the same or less amount of power and subsequently cooling
    • Leverage faster processors/controllers that use the same or less power
    • Apply applicable RAID level to application and data QoS requirements
    • Consolidate slower storage or servers to a faster, more energy-efficient solution
    • Use faster disk drives with capacity boost and that draw less power
    • Upgrade to newer, faster, denser, more energy-efficient technologies
    • Look beyond capacity utilization; keep response time and availability in mind
    • Leverage IPM, AVS, and other techniques to vary performance and energy usage
    • Manage data both locally and remote; gain control and insight before moving problems
    • Leverage a data footprint reduction strategy across all data and storage tiers
    • Utilize multiple data footprint techniques including archive, compression and de-dupe
    • Reduce data footprint impact, enabling higher densities of stored on-line data

    Find a balance between energy avoidance and energy efficiency, consolidation and business enablement for sustainably, hardware and software, best practices including policy and producers, as well as leveraging available financial rebates and incentives. Addressing green and PCFE issues is a process; there is no one single solution or magic formula.

    Efficient and Optimized IT Wheel of Oppourtunity

    Figure 3 Wheel of Opportunity – Various Techniques and Technologies for Infrastructure Optimization (Source: “The Green and Virtual Data Center” (CRC)

    Instead, leverage a combination of technologies, techniques, and best practices to address various issues and requirements is needed (Figure 3). Some technologies and techniques include among others infrastructure resource management (IRM), data management, archiving (including for non-compliance), and compression (on-line and off-line, primary and secondary) as well as de-dupe for backups, space saving snapshots, and effective use of applicable raid levels.

    Green washing and green hype may fade away, however power, cooling, footprint, energy (PCFE) and related issues and initiatives that enable IT infrastructure optimization and business sustainability will not fade away. Addressing IT infrastructure optimization and efficiency is thus essential to IT and business sustainability and growth in an environmentally friendly manner which enables shifting from talking about green to being green and efficient.
