Buzzword Bingo 1.0 – Are you ready for fall product announcemnts?

Ever play IT buzzword bingo or perhaps you have and not realized it?

Anyone can play, its easy and you don’t even need to know or understand the words or terms.

Its actually quite common and very easy, it goes like this, someone perhaps a vendor, var, media, analysts, pundit, blogger, twitter, customer/user, financier or whomever starts rattling of terms, phrases and acronyms in a discussion until some says or yells, “Bingo”, that is what I want or want to talk about or that applies to what Im interested in.  Buzzword bingo can be multi-directional, it can be played by customers and vendors alike, it can be played via product announcements, articles, white papers, blog posts, videos, presentations or webcasts you name it.

So lets give it a try with a simple version to get started, oh, some of the acronyms have multiple meanings as well just to make the game more interesting, so remember, yell bingo when something resonates, ready? Ok, let’s go with 8 Gb Fibre Channel (8GFC), 10GbE, AVO, Agent-less, Authentication, Archiving, Backup, Backup Service Provider (BSP), BC/DR, Buffer, Bus, Benchmarking, Blade servers, Bulk Storage, CAS, Capacity Planning, Capacity per watt, CDP, Converged Enhanced Ethernet (CEE), CIFS, Cloud, cloud computing, cloud storage, cloud it, cloud confusion, clusters, Clustered Storage, CNA, Compliance, Compression, Converged Networks, Cores, Driver, Data Center Ethernet (DCE), DLP, Domain, D2D2D, Data management, Data migration, De-duplication, De-dupe debates, Dual Boot, DPM, eDiscovery, Energy Star, EPA, Environmental Health and Safety (EHS), Encryption, Event Correlation, eWaste, Fibre Channel over Ethernet (FCoE), FCBB, File management, FLASH or flash, Gateway, Green, Grid, Hash table, Index, HA, Hypervisor, hyperv, HAL, I/O Virtualization (IOV), Inband, Inline, ITIL, InfiniBand, Infrastructure Resource Management (IRM), IOPS per watt, IPM & MAID 2.0, iSCSI, LAN, Look aside buffer, MAN, Mhz, Multi-Protocol Storage, Managed Service Processors, Provider (MSP), MIBS, MLC, Meta, NAS, NFS, NPVID, OS, Over clocking, Optimization, Partitions, Para-virtualization, PCIe, Policy Management, POTS, POST, Post processing, PIROMA, Power Cooling Floor-space EHS (PCFE), PCI SIG IOV, Pin count, Pin out, Pun up, Performance, pNFS, Removable Hard Disk Drive (RHDD), RAID 6, RAM, Replication, RoHS, Replication, REST, SAN, SaaS, SRA, SRM, SAS, SATA, Security, SLC, Snapshots, SMIS, SNMP, SOAP, SRM, SSD, Stack, Tape, Threads, Thin Provision, Tier 0, Unstructured data, VCB, VM, Vmworld, Virtualization, virtual memory, Vmotion, VMware, vcpu, VTL, WAN, WAAS, WADS, WAFS, WADM, Web 2.0 or xaaS (replace x with whatever letter you like, kind of like xSP ;) ).

Any bingos yet? Ok, enough is enough, will leave it here for now, maybe a future post for Buzzword Bingo 2.0 will include more technical terms and acronyms or excerpts from industry trade group dictionaries such as SNIA or glossaries such as those from mine and other books .

With a plethora of upcoming announcements, rest assured, there will be plenty of opportunities to brush up on buzzword bingo so get ready, practice and enjoy your next game.

Check out the news and portfolio as well as interesting links page to learn more about related topics.

Ok, nuff said.

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).

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.

All work and no play? Ok, how about an education half day?

This past week in between keynote talks and moderating panel discussions pertaining to IT infrastructure optimization (server, storage, networks, hardware, software, services, virtualization, etc.) in Seattle and Portland, I was able to take a rare couple of hours break and go on a non work related tour.

The tour was actually two tours in one, the 1st being the future of flight facility located adjacent (ok, across the runway) to the Boeing Everett large commercial aircraft facility, which is where the 2nd tour was.

There was a saying heard on the tour, as well as something seen on several signs and bumper stickers which is, “if it does not say Boeing, I’m not going”. Disclosure time, I did fly to Seattle on a Boeing product, however I flew home from Portland on an Airbus product, and in-between those two great cities, I traveled via Amtrak.

Having been in many other in interesting factories including those of GE Aircraft Engines, GE Appliances not to mention electrical power plants (another form of a factory) both Coal, Hydro and Nuclear as well as automotive/trucks, army tanks along with chemical manufacturing or processing sites among others, the Boeing tour is right up there if not at the top of the list.

Boeing Everett Plant - photo from Gregs iPhone
Here’s an iPhone photo of from the future of flight museum/facility of the Boeing Everett factory

To say the building is huge would be an understatement! In the above photo, on the left the blue doors are each about the size of a football field in size. The building is touted as the largest building by volume in the world, and once up close you can see why the key phrase is “by volume”. The place is huge! Click here to see some more information from Boeing about the site.

Boeing does not allow cameras, cell phones, MP3 players, purses, backpacks or fanny packs, essentially anything other than your wallet or what’s in your pocket during the tour, so sorry, no photos.  However, here are some links including a great website (flight blogger) where you can see what I saw as well as learn a lot more.

Boeing is in the process of developing two new commercial aircraft, the 747-8 and the 787 “Dream liner” (learn more here at Boeings newairplane.com site).

In the factory, on the 747 line, which is in the older part of the building (40+ years old), the first of what is the newest or essentially 3rd generation of the 40 year old 747 airplane was seen having had its fuselage sections joined hours before. In the photo found in the following link, the sections were hours away from being joined, and the vantage point of the tour can be seen in the background adjacent to where the large U.S. flag is seen.

Click here and here to see photos from Flightblogger.com of the new “next generation” 747-8F taken the day before the tour. Click here to see some images of the 787 dream liner, including this one here that had just been removed from the paint hanger and was parked on the ramp. I also saw this plane on the ramp that had just emerged from being painted.

Some perspectives that I found interesting from the tour included:

On the 747 line, there were plenty of factory sounds, pneumatic air tools, riveters, drills, hammering and activity one would expect in a large factory where there was a mix of hand building with tools and automation. However clearly, rooted in a 40+ year old technology that has been brought up to current generation standards, systems and technologies.

In the middle of the factory, where the newer 777 were being assembled, it looked like a newer program and processes including with moving assembly lines similar to what you would expect in a high volume factory. There were lots of people moving and installing things, you could see and hear work being done, however much more automated than on the larger 747 line, not surprising seeing the size of the new 747-8F.

At the opposite end of the factory, in a section that is only about 15 years old, you could tell the difference in the structure as you walk through the below factory floor access tunnels which are large enough for large automobiles to comfortably pass each other in. The tunnels were larger; there were more bulk fiber optic cables in the overhead conveyance racks and a generally newer look and feel. However once up on the observation level above the factory floor is where you could really see the difference.

At the end of the tour, we saw the brand new 787 dream liner being put together. This is a brand new plan that has yet to fly and that has been plagued by issues, some not so different to what we see with new IT technologies. The 787 is an all composite aircraft (ok, there are some small amounts of metal in some structures) that has its components built elsewhere and then flown to Everett for integration or final assembly.

In fact, back on July 8th, 2007, (e.g. 787), Boeing did a virtual physical rollout, that is, they put the incomplete plane together, painted it, rolled it out for the world to see and of course, people believed that it was ready to fly in a month or so. Guess what, most everyone fell for the demo and thought it to be real (hmmm, sounds like some trade shows I have been to or demo rooms I have seen ;) ), only to still be on the ground dealing with development issues.

Anyway, all that aside, what I saw on the 787 line were two aircraft, that were not surrounded by people with pneumatic tools, drills, riveters or making factory sounds or noises. Instead, what I saw looked more like what I see in many IT environments, which was a piece of hardware in the middle of the room, with people all around it with laptop, desktop or other workstation computers busily doing work.

There were so many workstations, laptops and other computers on the floor in makeshift cubicles, conferences rooms that there were even network switches/directors positioned at the end of row of these cubes and clusters of workers. Thus the impact of having the engineers close to where the work was being done, the impact of all of the documentation and paper (virtual paper) work that goes with new development and reliance on information systems for communications, collaborations, design, simulation, parts tracking and so forth.

The real takeaway for me was how from one end of the factory were signs of the past generation leveraging new technologies, the middle being a hybrid, and the other end being leading edge, yet so revolutionary that issues are still being worked out.

I thought to myself of some similarities between what I saw at Boeing and many IT environments. That is, extremes, the past and the future, what works today, what will be key for tomorrow, as well as hybrid environments.

Similar to IT, customers are buying, testing and deploying for early adoption new technologies such as SAS, FCoE, SSD, dedupe, thin provision, virtualization that will be key building blocks moving forward, yet at the same time leveraging the past including disk drives, tape, RAID, FC, iSCSI  and others buzzword bingo technology, techniques and three letter acronyms (TLAs). Thus I saw Boeing leveraging the past, building to the future, surviving and sustaining itself today, a balance of the old and the new, just like many IT environments.

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.

Figure 1 – Generic clustered storage model (Courtesy “The Green and Virtual Data Center  (CRC)”

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.

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.

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.

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.

Catch of the day or post of the day!

Ok, I know, its been a couple of weeks since my last post. Sure I have been tweeting now and then, attending several briefings with new emerging as well as existing vendors for up-coming announcements, not to mention getting some other content out from webcasts, to podcasts, or videos, interviews, articles, tips and presentations at various events, pertaining to Green IT, virtualization, cloud storage and computing, backup, data protection, performance, capacity planning among other topics.

Anyway, for now a quick post as I have many others that I have been wanting to do and will be doing soon, however wanted to get a few things out sooner vs. later, and after all, all work and no play makes for a dull day right?

Well, last week after spending a couple of days in Chicago at Storage Decisions where I presented a couple of sessions and recorded several videos, I had a chance to get out and do some fishing and catching. Fishing is always great, however catching (and release) is even more fun, especially when you can catch some, toss some, and keep some for dinner which is what occurred last week when my friend Rob and me ventured out for a couple of hours and found where the fish were (see picture) on the St. Croix river.

Catch of the Day

Rob on left (Bruins warm up jacket for Bass fishing), Greg on the right (Mustang PFD Jacket)

Catch of the day line-up
From right to left, bottle bass (caught at the dock ;) ), stripped bass, northern pike (swamp shark), more stripped bass, and another bottle bass (also caught at the dock).

Ok, nuff fish talk for now, back to work, get a few things done, and then maybe this weekend, get another blog post done, maybe some fishing, and enjoying the summer weather before heading off to Toronto on Monday for Storage Decisions on Tuesday, then a couple of webcasts and web radio events on Wednesday among other activities.

Hello From EMC World Bloggers Lounge

EMC Blogger Lounge at EMCworld The day is looking up, it started out early, too early with a 7AM flight to Orlando leaving a nice sunny day in MSP arriving in MCO (that’s Minneapolis and Orlando for those who don’t use IATA airport codes) during a heavy rainstorm with plenty of storm clouds in the area ;) .

Oh, for those concerned about green and flying, the Boeing 757 with a pretty full passenger load of about 150 including two search and rescue dogs (they were in the row behind me) got about 65 miles per gallon per passenger, not to shabby for the 2.5 hour flight.

Once registered at the event, I attended an analyst session this afternoon that included a question and answer discussion session with Joe Tucci and other EMC folks.

Now I’m spending a few minutes in the bloggers lounge (where there are also several twitters as well) having a much needed cappuccino and trying out my flip video camcorder.

Here’s a quick video taken with my new flip video camcorder I won in a raffle giveaway. Plenty of EMC and partner loggers as well as others have been coming and going, some you may even recognize in the video. The flip camcorder is pretty easy to use both in terms of setup, configuration, shooting 1st video, editing, and uploading for use in this blog post from EMCworld.

Time to get ready for some more meetings before a dinner event tonight and more meetings over the next couple of days, now back to your regularly scheduled programming, nuff said for now.

BTW – Anyone going to the Brocade margaritaville event tomorrow night in Orlando, just received my orange wrist band!

R U Twittering Yet?

For those of you who are twitter fans, you can skip this post if you like as you are already twittering and know what it’s about, however feel free to follow me if you are not already doing so @storage.

On the other hand, for those of you new or not familiar with twitter (click here to learn more and sign-up) also known as micro blogging, is yet another venue and means to communicate, collaborate, network or what have you. In a nutshell, twitter messages, posts or tweets are 140 characters that appear on your twitter page for followers to view and respond to. For longer tweets or long URL’s, tiny URL’s can be used.

You can also include other tweeters in a post so your post will appear on their pages for discussion. Tweets can also be forwarded to others via a RT or retweet. Tweets as they are refereed to can be done via a web interface, from an iphone or other mobile device, or via email such as Microsoft Outlook with OutTwit.

Think of twitter as a cross between blogging, texting, IM and a few other things smashed together. For the competitive or status seekers, there are even grading or ranking sites to see or show how you stack up or compare to others.

Some tweets are discussion points, some are smash or trash talk, some are adds or news feeds, some are random thoughts or musings. Some people tweet constantly while others tweet now and then with some actively following and tweeting, while others simply lurk. Some follow others who follow-them, others simply post and follow few if anyone. Tweeters range from corporate or organizations to individuals for work or for fun for almost any cause, its really up to you how, when, why and where you want to tweet from.

Here’s a link to a blog post that I did late last year about what I refer to as tiered communications. While some may have a strong preference for one medium or venue vs. another, I see the different social networking, web 2.0 and related venues including facebook, twitter, friend feed, linkedin, plaxo, blogs, RSS, web sites and IM among others as different tiers and tools for communicating.

Check twitter out when you get a chance and start tweeting if the spirit so moves you, tweet you soon, however word of caution, tweeting can be addictive for some!

I can be found and followed @storageio or www.twitter.com/storageio and happy tweekend as its Friday.

U.S. EPA Looking for Industry Input on Energy Star for Storage

Following up on previous blog posts, here is some information that the U.S. EPA is looking for comments from industry on an Energy Start for enterprise storage program following on the heels of the Energy Star for Server program.

US EPA Energy Star LogoUS EPA Energy Star wants and needs you!
U.S. EPA Energy Star Wants and Needs You!

Here’s the message received from the EPA via their mailing list this past week (in italics below):

Dear Enterprise Storage Equipment Manufacturers and Other Interested Parties:

Please see the attached letter from the U.S. Environmental Protection Agency (EPA) announcing their intent to pursue development of an ENERGY STAR specification for Enterprise Storage equipment.  If you have any questions or concerns, please contact Andrew Fanara, EPA, at fanara.andrew@epa.gov or Stephen Pantano, ICF International, at spantano@icfi.com.

Thank you for your support of ENERGY STAR.

Here’s the intro letter excerpted from the above email notification (in italics below):

April 23, 2009

Dear Enterprise Storage Equipment Manufacturers and Other Interested Parties:

This letter is intended to inform all stakeholders that the U.S. Environmental Protection Agency (EPA) intends to continue its efforts towards the development of an ENERGY STAR® specification for enterprise data storage equipment. Following is an outline of EPA’s general goals and next steps.


ENERGY STAR is a voluntary partnership between government, businesses, and purchasers designed to encourage the manufacture, purchase, and use of efficient products to help protect the environment. Products that earn the ENERGY STAR prevent greenhouse gas emissions by meeting strict energy efficiency guidelines. Manufacturers that qualify their products to meet ENERGY STAR requirements may use the label as a tool to educate their customers about the enhanced value of these products.

To date:
•More than 2,000 manufacturers are partnering with ENERGY STAR,
•More than 40,000 product models carry the ENERGY STAR label across more than 50 product categories,
•More than 70% of Americans recognize the ENERGY STAR label,
•Consumers have purchased more than 2.5 billion ENERGY STAR qualified products, and
•Americans, with the help of ENERGY STAR, saved enough energy in 2008 to avoid greenhouse gas emissions equivalent to those from 29 million cars — while saving $19 billion on utility bills.

In the last several years, the energy saving opportunities in data centers have been well documented. However, barriers to energy efficiency still persist and need to be addressed. EPA is pursuing a dual strategy to overcome these challenges by helping purchasers more easily identify energy efficient IT equipment with the use of the ENERGY STAR designation, and by encouraging organizations to benchmark the energy performance of their data centers.


In pursuit of this strategy, EPA will introduce an ENERGY STAR Computer Server specification in the coming weeks. In addition, EPA recently conducted a scoping effort to evaluate enterprise storage products for inclusion in the ENERGY STAR program. EPA reviewed available market research and facilitated discussions with product manufacturers, industry associations, and other interested parties. EPA concluded that IT purchasers would benefit from access to standardized information about the energy performance of storage equipment made available through the ENERGY STAR program. As a result, EPA intends to begin the specification development process. Details on this process will be forthcoming in the next several weeks.

To be added to the enterprise storage e-mail distribution list, please send your full contact information to Stephen Pantano at spantano@icfi.com. To stay informed about the ENERGY STAR specification development process for computer servers and other EPA data center initiatives please visit: www.energystar.gov/datacenters.


Thank you for your continued support of ENERGY STAR and please direct additional questions to Andrew Fanara at fanara.andrew@epa.gov or Stephen Pantano of ICF International, at spantano@icfi.com.

Sincerely,

Andrew Fanara
U.S. Environmental Protection Agency, Climate Protection Partnerships Division ENERGY STAR Program Manager

My take on the Energy Star programs is that as long as they add value including reflecting how energy is effectively used both when IT equipment such as servers and storage are in use, as well as in energy saving or avoidance modes are reflected, they can and should be a good thing.

However industry will need to work together across different trade and focus groups as well as factor in how supporting metrics will be applicable and reflective thus accepted by IT data center environments. This means metrics and measurements for both active or working while in use energy efficiency modes such as IOPS, bandwidth, messages or transactions, files or videos per watt of energy, as well as metrics for in-active or dormant data such as capacity per watt per usable footprint. Check out Chapter 5 (Measurements and Metrics) in "The Green and Virtual Data Center" (CRC) to learn more.

Various industry trade and focus groups including Storage Performance Council (SPC), SNIA GSI, Green Grid, SPEC and others are working on various metrics and aligning themselves to work with EPA. If you are in an IT data center involved with servers or storage, consider getting involved with one or more of these groups to help influence and shape what these programs will look like or affect your organization in the future.

Ok, nuff said.
