The other Green Storage: Efficiency and Optimization

Some believe that green storage is specifically designed to reduce power and cooling costs.

The reality is that there are many ways to reduce environmental impact while enhancing the economics of data storage besides simply booting utilizing.

These include optimizing data storage capacity as well as boosting performance to increase productivity per watt of energy used when work needs to be done.

Some approaches require new hardware or software while others can be accomplished with changes to management including reconfiguration leveraging insight and awareness of resource needs.

Here are some related links:

Green IT and Virtual Data Centers

Green IT and virtual data centers are no fad nor are they limited to large-scale environments.

Paying attention to how resources are used to deliver information services in a flexible, adaptable, energy-efficient, environmentally, and economically friendly way to boost efficiency and productivity are here to stay.

Read more here in the article I did for the folks over at Enterprise Systems Journal.

Acadia VCE: VMware + Cisco + EMC = Virtual Computing Environment

Was today the day the music died? (click here or here if you are not familar with the expression)

Add another three letter acronym (TLA) to your IT vocabulary if you are involved with server, storage, networking, virtualization, security and related infrastructure resource management (IRM) topics.

That new TLA is Virtual Computing Environment (VCE), a coalition formed by EMC and Cisco along with partner Intel called Acadia that was announced today. Of course, EMC who also happens to own VMware for virtualization and RSA for security software tools bring those to the coalition (read press release here).

For some quick fun, twittervile and the blogosphere have come up with other meanings such as:

VCE = Virtualization Communications Endpoint
VCE = VMware Cisco EMC
VCE = Very Cash Efficient
VCE = VMware Controls Everything
VCE = Virtualization Causes Enthusiasm
VCE = VMware Cisco Exclusive

Ok, so much for some fun, at least for now.

With Cisco, EMC and VMware announcing their new VCE coalition, has this signaled the end of servers, storage, networking, hardware and software for physical, virtual and clouding computing as we know it?

Does this mean all other vendors not in this announcement should pack it up, game over and go home?

The answer in my perspective is NO!

No, the music did not end today!

NO, servers, storage and networking for virtual or cloud environments has not ended.

Also, NO, other vendors do not have to go home today, the game is not over!

However a new game is on, one that some have seen before, for others it is something new, exciting perhaps revolutionary or an industry first.

What was announced?
Figure 1 shows a general vision or positioning from the three major players involved along with four tenants or topic areas of focus. Here is a link to a press release where you can read more.

CiscoVirtualizationCoalition.png
Figure 1: Source: Cisco, EMC, VMware

General points include:

  • A new coalition (e.g. VCE) focused on virtual compute for cloud and non cloud environments
  • A new company Acadia owned by EMC and Cisco (1/3 each) along with Intel and VMware
  • A new go to market pre-sales, service and support cross technology domain skill set team
  • Solution bundles or vblocks with technology from Cisco, EMC, Intel and VMware

What are the vblocks and components?
Pre-configured (see this link for a 3D model), tested, and supported with a single throat to choke model for streamlined end to end management and acquisition. There are three vblocks or virtual building blocks that include server, storage, I/O networking, and virtualization hypervisor software along with associated IRM software tools.

Cisco is bringing to the game their Unified Compute Solution (UCS) server along with Nexus 1000v and Multilayer Director (MDS) switches, EMC is bringing storage (Symmetrix VMax, CLARiiON and unified storage) along with their RSA security and Ionix IRM tools. VMware is providing their vSphere hypervisors running on Intel based services (via Cisco).

The components include:

  • EMC Ionix management tools and framework – The IRM tools
  • EMC RSA security framework software – The security tools
  • EMC VMware vSphere hypervisor virtualization software – The virtualization layer
  • EMC VMax, CLARiiON and unified storage systems – The storage
  • Cisco Nexus 1000v and MDS switches – The Network and connectivity
  • Cisco Unified Compute Solution (UCS) – The physical servers
  • Services and support – Cross technology domain presales, delivery and professional services

CiscoEMCVMwarevblock.jpg
Figure 2: Source: Cisco vblock (Server, Storage, Networking and Virtualization Software) via Cisco

The three vblock models are:
Vblock0: entry level system due out in 2010 supporting 300 to 800 VMs for initial customer consolidation, private clouds or other diverse applications in small or medium sized business. You can think of this as a SAN in a CAN or Data Center in a box with Cisco UCS and Nexus 1000v, EMC unified storage secured by RSA and VMware vSphere.

Vblock1: mid sized building block supporting 800 to 3000 VMs for consolidation and other optimization initiatives using Cisco UCS, Nexus and MDS switches along with EMC CLARiiON storage secured with RSA software hosting VMware hypervisors.

Vblock2 high end supporting up 3000 to 6000 VMs for large scale data center transformation or new virtualization efforts combing Cisco Unified Computing System (UCS), Nexus 1000v and MDS switches and EMC VMax Symmetix storage with RSA security software hosting VMware vSpshere hypervisor.

What does this all mean?
With this move, for some it will add fuel to the campfire that Cisco is moving closer to EMC and or VMware with a pre-nuptial via Acadia. For others, this will be seen as fragmentation for virtualization particularly if other vendors such as Dell, Fujitsu, HP, IBM and Microsoft among others are kept out of the game, not to mention their channels of vars or IT customers barriers.

Acadia is a new company or more precisely, a joint venture being created by major backers EMC and Cisco with minority backers being VMware and Intel.

Like any other joint ventures, for examples those commonly seen in the airline industry (e.g. transportation utility) where carriers pool resources such as SkyTeam whose members include Delta who had a JV with Airframe owner of KLM who had a antitrust immunity JV with northwest (now being digested by Delta).

These joint ventures can range from simple marketing alliances like you see with EMC programs such as their Select program to more formal OEM to ownership as is the case with VMware and RSA to this new model for Acadia.

An airline analogy may not be the most appropriate, yet there are some interesting similarities, least of which that air carriers rely on information systems and technologies provided by members of this collation among others. There is also a correlation in that joint ventures are about streamlining and creating a seamless end to end customer experience. That is, give them enough choice and options, keep them happy, take out the complexities and hopefully some cost, and with customer control come revenue and margin or profits.

Certainly there are opportunities to streamline and not just simply cut corners, perhaps that’s another area or analogy with the airlines where there is a current focus on cutting, nickel and dimming for services. Hopefully the Acadia and VCE are not just another example of vendors getting together around the campfire to sing Kumbaya in the name of increasing customer adoption, cost cutting or putting a marketing spin on how to sell more to customers for account control.

Now with all due respect to the individual companies and personal, at least in this iteration, it is not as much about the technology or packaging. Likewise, while important, it is also not just about bundling, integration and testing (they are important) as we have seen similar solutions before.

Rather, I think this has the potential for changing the way server, storage and networking hardware along with IRM and virtualization software are sold into organizations, for the better or worse.

What Im watching is how Acadia and their principal backers can navigate the channel maze and ultimately the customer maze to sell a cross technology domain solution. For example, will a sales call require six to fourteen legs (e.g. one person is a two legged call for those not up on sales or vendor lingo) with a storage, server, networking, VMware, RSA, Ionix and services representative?

Or, can a model to drive down the number of people or product specialist involved in a given sales call be achieved leveraging people with cross technology domain skills (e.g. someone who can speak server and storage hardware and software along with networking)?

Assuming Acadia and VCE vblocks address product integration issues, I see the bigger issue as being streamlining the sales process (including compensation plans) along with how partners are dealt with not to mention customers.

How will the sales pitch be to the Cisco network people at VARs or customer sites, or too the storage or server or VMware teams, or, all of the above?

What about the others?
Cisco has relationships with Dell, HP, IBM, Microsoft and Oracle/Sun among others that they will be stepping even more on the partner toes than when they launched the UCS earlier this year. EMC for its part if fairly diversified and is not as subservient to IBM however has a history of partnering with Dell, Oracle and Microsoft among others.

VMware has a smaller investment and thus more in the wings as is Intel given that both have large partnership with Dell, HP, IBM and Microsoft. Microsoft is of interest here because on one front the bulk of all servers virtualized into VMware VMs are Windows based.

On the other hand, Microsoft has their own virtualization hypervisor HyperV that depending upon how you look at it, could be a competitor of VMware or simply a nuisance. Im of the mindset that its still to early and don’t judge this game on the first round which VMware has won. Keep in mind the history such as desktop and browser wars that Microsoft lost in the first round only to come back strong later. This move could very well invigorate Microsoft, or perhaps Oracle, Citrix among others.

Now this is far from the first time that we have seen alliances, coalitions, marketing or sales promotion cross technology vendor clubs in the industry let alone from the specific vendors involved in this announcement.

One that comes to mind was 3COMs failed attempt in the late 90s to become the first traditional networking vendor to get into SANs, that was many years before Cisco could spell SAN let alone their Andiamo startup incubated. The 3COM initiative which was cancelled due to financial issues literally on the eve of rollout was to include the likes of STK (pre-sun), Qlogic, Anchor (People were still learning how to spell Brocade), Crossroads (FC to SCSI routers for tape), Legato (pre-EMC), DG CLARiiON (Pre-EMC), MTI (sold their patents to EMC, became a reseller, now defunct) along with some others slated to jump on the bandwagon.

Lets also not forget that while among the traditional networking market vendors Cisco is the $32B giant and all of the others including 3Com, Brocade, Broadcom, Ciena, Emulex, Juniper and Qlogic are the seven plus dwarfs. However, keep the $23B USD Huawei networking vendor that is growing at a 45% annual rate in mind.

I would keep an eye on AMD, Brocade, Citrix, Dell, Fujitsu, HP, Huawei, Juniper, Microsoft, NetApp, Oracle/Sun, Rackable and Symantec among many others for similar joint venture or marketing alliances.

Some of these have already surfaced with Brocade and Oracle sharing hugs and chugs (another sales term referring to alliance meetings over beers or shots).

Also keep in mind that VMware has a large software (customer business) footprint deployed on HP with Intel (and AMD) servers.

Oh, and those VMware based VMs running on HP servers also just happen to be hosting in their neighbor of 80% or more Windows based guests operating systems, I would say its game on time.

When I say its game on time, I dont think VMware is brash enough to cut HP (or others) off forcing them to move to Microsoft for virtualization. However the game is about control, control of technology stacks and partnerships, control of vars, integrators and the channel, as well as control of customers.

If you cannot tell, I find this topic fun and interesting.

For those who only know me from servers they often ask when did I learn about networking to which I say check out one of my books (Resilient Storage Networks-Elsevier). Meanwhile for others who know me from storage I get asked when did I learn about or get into servers to which I respond about 28 years ago when I worked in IT as the customer.

Bottom line on Acadia, vblocks and VCE for now, I like the idea of a unified and bundled solution as long as they are open and flexible.

On the other hand, I have many questions and even skeptical in some areas including of how this plays out for Cisco and EMC in terms of if it can be a unifier or polarized causing market fragmentation.

For some this is or will be dejavu, back to the future, while for others it is a new, exciting and revolutionary approach while for others it will be new fodder for smack talk!

More to follow soon.

Saving Money with Green IT: Time To Invest In Information Factories

There is a good and timely article titled Green IT Can Save Money, Too over at Business Week that has a familiar topic and theme for those who read this blog or other content, articles, reports, books, white papers, videos, podcasts or in-person speaking and keynote sessions that I have done..

I posted a short version of this over there, here is the full version that would not fit in their comment section.

Short of calling it Green IT 2.0 or the perfect storm, there is a resurgence and more importantly IMHO a growing awareness of the many facets of Green IT along with Green in general having an economic business sustainability aspect.

While the Green Gap and confusion still exists, that is, the difference between what people think or perceive and actual opportunities or issues; with growing awareness, it will close or at least narrow. For example, when I regularly talk with IT professionals from various sized, different focused industries across the globe in diverse geographies and ask them about having to go green, the response is in the 7-15% range (these are changing) with most believing that Green is only about carbon footprint.

On the other hand, when I ask them if they have power, cooling, floor space or other footprint constraints including frozen or reduced budgets, recycling along with ewaste disposition or RoHS requirements, not to mention sustaining business growth without negatively impacting quality of service or customer experience, the response jumps up to 65-75% (these are changing) if not higher.

That is the essence of the green gap or disconnect!

Granted carbon dioxide or CO2 reduction is important along with NO2, water vapors and other related issues, however there is also the need to do more with what is available, stretch resources and footprints do be more productive in a shrinking footprint. Keep in mind that there is no such thing as an information, data or processing recession with all indicators pointing towards the need to move, manage and store larger amounts of data on a go forward basis. Thus, the need to do more in a given footprint or constraint, maximizing resources, energy, productivity and available budgets.

Innovation is the ability to do more with less at a lower cost without compromise on quality of service or negatively impacting customer experience. Regardless of if you are a manufacturer, or a service provider including in IT, by innovating with a diverse Green IT focus to become more efficient and optimized, the result is that your customers become more enabled and competitive.

By shifting from an avoidance model where cost cutting or containment are the near-term tactical focus to an efficiency and productivity model via optimization, net unit costs should be lowered while overall service experience increase in a positive manner. This means treating IT as an information factory, one that needs investment in the people, processes and technologies (hardware, software, services) along with management metric indicator tools.

The net result is that environmental or perceived Green issues are addressed and self-funded via the investment in Green IT technology that boosts productivity (e.g. closing or narrowing the Green Gap). Thus, the environmental concerns that organizations have or need to address for different reasons yet that lack funding get addressed via funding to boost business productivity which have tangible ROI characteristics similar to other lean manufacturing approaches.

Here are some additional links to learn more about these and other related themes:

Have a read over at Business Week about how Green IT Can Save Money, Too while thinking about how investing in IT infrastructure productivity (Information Factories) by becoming more efficient and optimized helps the business top and bottom line, not to mention the environment as well.

PUE, Are you Managing Power, Energy or Productivity?

With a renewed focus on Green IT including energy Efficiency and Optimization of servers, storage, networks and facilities, is your focus on managing power, energy, or, productivity?

For example, do you use or are interested in metrics such as Greengrid PUE or 80 Plus efficient power supplies along with initiatives such as EPA Energy Star for servers and emerging Energy Star for Data Center for Storage in terms of energy usage?

Or are you interested in productivity such as amount of work or activity that can be done in a given amount of time,or how much information can be stored in a given footprint (power, cooling, floor space, budget, management)?

For many organizations, there tends to be a focus and in both managing power along with managing productivity. The two are or should interrelated, however there are some disconnects with some emphasis and metrics. For example, the Green grid PUE is a macro facilities centric metric that does not show the productivity, quality or measure of services being delivered by a data center or information factory. Instead, PUE provides a gauge of how the habitat, that is the building and power distribution along with cooling are efficient with respect to the total energy consumption of IT equipment.

As a refresher, PUE is a macro metric that is essentially a ratio of how much total power or energy goes into a facility vs. the amount of energy used by IT equipment. For example, if 12Kw (smaller room/site) or 12Mw (larger site) are required to power an IT data center or computer room for that matter, and of that energy load, 6kWh or 6Mw, the PUE would be 2. A PUE of 2 is an indicator that 50% of energy going to power a facility or computer room goes towards IT equipment (servers, storage, networks, telecom and related equipment) with the balance going towards running the facility or environment which typically has had the highest percentage being HVAC/cooling.

In the case of EPA Energy Star for Data Centers which initially is focused on the habitat or facility efficiency, the answer is measuring and managing energy use and facility efficiency as opposed to productivity or useful work. The metric for EPA Energy Star for Data Center initially will be Energy Usage Effectiveness (EUE) that will be used to calculate a ratting for a data center facility. Those data centers in the top25 percentile will qualify for Energy Star certification.

Note the word energy and not power which means that the data center macro metric based on Green grid PUE rating looks at all source of energy used by a data center and not just electrical power. What this means is that a macro and holistic facilities energy consumption could be a combination of electrical power, diesel, propane or natural gas or other fuel sources to generate or create power for IT equipment, HVAC/Cooling and other needs. By using a metric that factor in all energy sources, a facility that uses solar, radiant, heat pumps, economizers or other techniques to reduce demands on energy will make a better rating.

By using a macro metric such as EUE or PUE (ratio = Total_Power_Used / IT_Power_Needs), a starting point is available to decide and compare efficiency and cost to power or energize a facility or room also known as a habitat for technology.

Managing Productivity of Information Factories (E.g. Data Centers)
What EUE and PUE do not reflect or indicate is how much data is processed, moved and stored by servers, storage and networks within a facility. On the other hand or extreme from macro metrics are micro or component metrics that gauge energy usage on an individual device basis. Some of these micro metrics may have activity or productivity indicator measurements associated with them, some don’t. Where these leave a big gap and opportunity is to fill the span between the macro and micro.

This is where work is being done by various industry groups including SNIA GSI, SPC and SPEC among others along with EPA Energy Star among others to move beyond macro PUE indicators to more granular effectiveness and efficiency metrics that reflect productivity. Ultimately productivity is important to gauge,  the return on investment and business value of how much data can be processed by servers, moved via networks or stored on storage devices in a given energy footprint or cost.

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 do same amount of work (or storage data) however with 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. Clock here to read more about Shifting from energy avoidance to energy efficiency.

Watch for new metrics looking at productivity and activity for servers, storage and networks ranging from MHz or GHz per watt, transactions or IOPS per watt, bandwidth, frames or packets processed per watt or capacity stored per watt in a given footprint. One of the confusing metrics is Gbytes or Tbytes per watt in that it can mean storage capacity or bandwidth, thus, understand the context of the metric. Likewise watch for metrics that reflect energy usage for active along with in-active including idle or dormant storage common with archives, backup or fixed content data.

What this all means is that work continues on developing usable and relevant metrics and measurement not only for macro energy usage, also, to gauge the effectiveness of delivering IT services. The business value proposition of driving efficiency and optimization including increased productivity along with storing more information in a given footprint is to support density and business sustainability.

Storage Efficiency and Optimization – The Other Green

For those of you in the New York City area, I will be presenting live in person at Storage Decisions September 23, 2009 conference The Other Green, Storage Efficiency and Optimization.

Throw out the "green“: buzzword, and you’re still left with the task of saving or maximizing use of space, power, and cooling while stretching available IT dollars to support growth and business sustainability. For some environments the solution may be consolation while others need to maintain quality of service response time, performance and availability necessitating faster, energy efficient technologies to achieve optimization objectives.

To accomplish these and other related issues, you can turn to the cloud, virtualization, intelligent power management, data footprint reduction and data management not to mention various types of tiered storage and performance optimization techniques. The session will look at various techniques and strategies to optimize either on-line active or primary as well as near-line or secondary storage environment during tough economic times, as well as to position for future growth, after all, there is no such thing as a data recession!

Topics, technologies and techniques that will be discussed include among others:

  • Energy efficiency (strategic) vs. energy avoidance (tactical), whats different between them
  • Optimization and the need for speed vs. the need for capacity, finding the right balance
  • Metrics & measurements for management insight, what the industry is doing (or not doing)
  • Tiered storage and tiered access including SSD, FC, SAS, tape, clouds and more
  • Data footprint reduction (archive, compress, dedupe) and thin provision among others
  • Best practices, financial incentives and what you can do today

This is a free event for IT professionals, however space I hear is limited, learn more and register here.

For those interested in broader IT data center and infrastructure optimization, check out the on-going seminar series The Infrastructure Optimization and Planning Best Practices (V2.009) – Doing more with less without sacrificing storage, system or network capabilities Seminar series continues September 22, 2009 with a stop in Chicago. This is also a free Seminar, register and learn more here or here.

    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.

    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.

    Happy Earth Day 2009

    Its that time of the year again, that’s right, earth day April 22 2009!

    If you frequent this blog, visit my websites (StorageIO, The Green and Virtual Data Center or Green Data Storage), track twitter, attended any of my speaking engagements, webcast, podcast, videos, radio interviews, seen press or media coverage, not to mention read any of my reports, articles, tips or books, it should not come as a surprise that I have something to say about Green IT and closing the Green Gap.

    The Green and Virtual Data Center (CRC)

    Common themes have included awareness of the green gap and how to address or close it including discussions around IT transformation, infrastructure optimization, boosting productivity and efficiency to support business sustainability among others. While its tempting to go on and on about different trends, topics, techniques, technologies and related themes with a back drop of earth day, lets leave it at this for now in the sake of brevity and efficiency.

    There’s plenty of existing content to be recycled and reused or seen and viewed for today including at some of the above links. However, rest assured, there is more content in the works pertaining to enabling Green IT with a focus around data center productivity, efficiency and sustainability, doing more with less, or, doing more with what is available.

    So happy earth day 2009, chat with you again soon.

    Ok, nuff said.

    Storage Effiency and Optimizaiton – Balancing Time and Space

    Storage I/O trends

    Here’s a link to the presentation I recently delivered at the Spring 2009 Minneapolis/St. Paul area CMG (Computer Measurement Group – CMG) March 20th, 2009 hosted by Nexus Information Systems and organized by Tom Becchetti. The theme of the event was "Is your storage efficient? There are many ways to rate your storage, how does yours stack up?". Tom organized a great event as usual with a diverse set of speakers for the well attended event graciously hosted by Keith Norbie of Nexus at their Minnetonka facility. The title of my presentation was "Storage Efficiency: Mirror Mirror On The Wall, Who or What is The Most Efficient of Them All? Finding the Correct Balance" that looked at balancing the need to reduce (or maximize) space (utilization) with time (performance) to meet different requirements including maintaining quality of service, response time and availability.

    Keeping in mind that there is no such thing as a data or I/O performance recession, there is a common myth that storage optimization or efficiency is all about driving up storage space capacity utilization which can be true for some environments, applications, data or storage types. However there is also the need to maintain or boost performance, reduce response time and latency, doing more work in a more productive and efficieny manner. Not all data or storage can be consolidated to boost utilization without concern for degrading or in any other way penalizing performance, response time or availability.

    Thus it is about time and space, that is, balancing data movement and processing rates with storage space capacity utilization and that sometimes, more is not better for performance when it comes to ratios or the number of components in a solution.

    Likewise there is the need to balance energy avoidance with energy efficient, balancing the need to store more data in a smaller footprint using less energy and the need to process more data in less time efficiently for productivity.

    These and other related themes are expanded on in more detail in my book "The Green and Virtual Data Center" (CRC). These and other related themes will covered in one of my upcoming presentations (The Other Green — Storage Efficiency and Optimization) at StorageDecisions in Chicago the week of June 1st, 2009, as well as in various seminars and events that I will be involved in the coming weeks and months.

    Thanks to all those who helped organize, support, sponsored, presented and attended the recent CMG event, look forward to seeing or hearing from you all again soon.

    Storage Decisions Spring 2009 Sessions Update

    StorageDecisions Logo

    The conference lineup and details for the Spring 2009 Storage Decisions event (June 1st and 2nd) in Chicago is coming together including two talks/presentations that I will be doing. One will be in Track 2 (Disaster Recovery) titled "Server Virtualization, Business Continuance and Disaster Recovery" and the other in Track 6 (Management/Executive) titled "The Other Green — Storage Efficiency and Optimization" with both sessions leveraging themes and topics from my new book "The Green and Virtual Data Center" (CRC).

    Track 2: Disaster Recovery
    Server Virtualization, Business Continuance and Disaster Recovery
    Presented by Greg Schulz, Founder and Senior Analyst, StorageIO
    Server virtualization has the potential to bring sophisticated business continuance (BC) and disaster recovery (DR) techniques to organizations that previously didn’t have the means to adopt them. Likewise, virtualized as well as cloud environments need to be included in a BC/DR plan to enable application and data availability. Learn tips and tricks on building an accessible BC/DR strategy and plan using server virtualization and the storage products that enable efficient, flexible green and virtual data centers.

    Topics include:
    * Cross technology domain data protection management
    * Tiered data protection to stretch your IT budget dollar
    * What’s needed to enable BC/DR for virtualized environments
    * How virtualization can enable BC/DR for non-virtualized environments
    * General HA, BC/DR and data protection tips for virtual environments

    Track 6: Management/Executive
    The Other Green — Storage Efficiency and Optimization
    Throw out the "green“: buzzword, and you’re still left with the task of saving or maximizing use of space, power, and cooling while stretching available IT dollars to support growth and business sustainability. For some environments the solution may be consolation while others need to maintain quality of service response time, performance and availability necessitating faster, energy efficient technologies to achieve optimization objectives. To accomplish these and other related issues, you can turn to the cloud, virtualization, intelligent power management, data footprint reduction and data management not to mention various types of tiered storage and performance optimization techniques. The session will look at various techniques and strategies to optimize either on-line active or primary as well as near-line or secondary storage environment during tough economic times, as well as to position for future growth, after all, there is no such thing as a data recession!

    Topics include:
    * Energy efficiency (strategic) vs. energy avoidance (tactical)
    * Optimization and the need for speed vs. the need for capacity
    * Metrics and measurements for management insight
    * Tiered storage and tiered access including SSD, FC, SAS and clouds
    * Data footprint reduction (archive, compress, dedupe) and thin provision
    * Best practices, financial incentives and what you can do today

    See you in Chicago in June if not before then. Learn more about other upcoming events and activities on the StorageIO events page.

    Cheers gs
