Did someone forget to tell Dell that Tape is dead?

Storage I/O trends

Did someone forget to send a memo to Dell that magnetic tape is dead, or, perhaps pre-occupied with other activities? Maybe no body at Dell read the “virtual” or “fictional” memo that tape is dead?

Ok, enough with the cynicism and joking around, tape is not dead (See recent Computerworld and Dell story) and Dell is one of several vendors including IBM who still find time to talk about tape as part of a solution to different customer and environment needs.

Sure, tape might be in or heading into its golden years or what can also be called the plateau of productivity (for customers) or profitability (for some vendors), tape does not get the marketing dollars and media coverage as its been around as a technology for a long time and their are cooler and niftier (techno term) things to discuss including disk based backup and data protection, CDP, VTLs, de-dupe debates, clusters, grids and clouds, FCoE vs. iSCSI, NAS, SAS, virtualization, OSD and pretty much anything except tape.

However, the reality is that many organizations, particular larger organizations still use and rely on tape based data protection for backup/BC/DR as well as archive for compliance and non-compliance data retention or data preservation activities, in some cases complimenting and co-existing with disk based solutions.

Disk to disk (D2D) based backups and data protection certainly continue to gain adoption and deployments in both large and small environments, however, the shift to disk based data protection, or, clinging to tape with a death grip does not have to be, nor should it be an all or nothing value proposition, that is, they can and do co-exist for different uses and purposes leveraging the various economics and benefits of the technologies to address various tasks and requirements.

New and emerging technologies certainly need to be discussed, dissected, developed and deployed as they are the future for maintaining and sustaining business growth via IT service delivery in economical and reliable fashion, that is, apply what technologies makes economic and business sense at a given point in time to minimize risk while maximizing useful benefits to your business.

Ok, nuff said.

IT Belt Tightening and Stratigies for IT Economic Sustainment

Storage I/O trends

There’s been and will continue to be lots of talk around tightening IT budgets and spending. Here’s a link to a piece by Chris Preimesberger over at eWeek titled “How the ‘Down’ Macroeconomy Will Impact the Data Storage Sector”.

Here’s another related piece by Marty Foltyn over on Internet News that looks at “Storage Technologies for a Slowing Economy”.

A macro trend that Im seeing and hearing more often is that with the demise or should I say, falling out of favor of Green hype and Green washing, there is a growing realization of the practical aspects of boosting efficiency and productivity with a by-product of being environmental friendly while addressing economic issues.

The so called Green Gap (See here, here, here, here, and here) exists between green hype and rhetoric which is now destined for the endangered species or extinction list, while core issues including power, cooling, floor space/footprint and environmental health & safety (EH&S) known as PCFE that need to be addressed are in fact covered under the broader green umbrella.

With the growing realization that efficiency gains that can boost IT productivity to sustain and enable business and economic growth also help the environment, there is awareness that those initiatives and activities that address PCFE and related issues are in fact green and part of many organizations agendas and budgets. Consequently going green for the sake of going green may be falling out of favor or off of budgets for many, addressing PCFE related issues to sustain business and economic growth are gaining in popularity though not always associated with as being green.

Thus in tough economic times where dollars and productivity become important, the new green will be that of efficiency and productivity with a by-product benefit being to help the environment, some of the themes in my book, The Green and Virtual Data Center (Auerbach) that you can pre-order now at Amazon.com and other venues around the world.

From ILM to IIM, Is this a solution sell looking for a problem?

Storage I/O trends

Enterprise Storage Forum has a new piece about what could be the successor to ILM from a marketing rallying cry perspective in the form of Intelligent Information Management (IIM).

Information management is an important topic, however, given tough economic times, can IIM be joined into some other discussions about efficiency and boosting productivity to help justify its cost what ever that cost may be in terms of more hardware, software and people to carry out? With EMC and Gartner banging the drum, it will be interesting to see who else jumps on the IIM bandwagon.

On the other hand, lets see what over variations surface perhaps an VIIM (Virtualized IIM), or a IIMaaS (IIM as a Service), or how about Cloud IIM or GIIM (Green IIM) among others like xIIM where you plug what ever letter you want in front if IIM (something that someone missed out on a few years ago by not grabbing xLM).

While I see the importance of data management, the bottom line is going to be how to budget and build a business case when sustaining business growth in tough economic times is a common theme. Hopefully we can see some business case and justifications that can involve some self-funded, that is, the cost of adopting and deploying IIM is covered by the savings in associated hardware and software management and maintenance fees as well as a means of boosting overall IT and data management productivity.

Tape Talk – Changing Role of Tape

Storage I/O trends

Here’s a link to a new article over at Enterprise Storage Forum titled “The Changing Role of Tape” for those of you who still use or care to admit to using magnetic tape as part of your data protection (backup, BC, DR) and data preservation (e.g. archiving and compliance) strategies.

Disk based solutions continue to grow in adoption for data protection, however tape remains relevant taking on different roles, similar to how disk drives are taking on different roles as FLASH and RAM based SSD continue to evolve and grow in terms of customer deployment adoption. Consequently, despite the continued hype that tape is dead, the reality is that tape remains on of if not the most energy-efficient or green storage mediums of in-active, off-line data in a given footprint and cost basis.

Tape is still being used in many environments particularly more so in larger environments with a focus shifting towards supporting ultra-dense large full backups that have been copied from disk to disk based backups as well as for archives.

Disk based data protection particularly with virtual tape libraries (VTLs) that combine data footprint reduction techniques such as compression, de-dupe, replication and migration to tape capabilities continue to gain in popularity as a convenient way to migrate from tape based backups to disk based backup preserving investment in existing people skills, policies, rules and software.

Ok, nuff said.

Escape From New York – Back from Storage Decisions NY 2008

Storage I/O trends

This past week I was in New York City (NYC) presenting at the IT professionals (e.g. customer) focused Storage Decisions event where I presented several sessions (See previous posting) including Green and Energy Efficient Storage Solutions ? Practical Ways to Reduce Power Consumption or Doing More with Less on Tuesday, and Clustered Storage ? From SMB, to Scientific, to Social Networking and Web 2.0 on Wednesday morning (Watch for TechTarget to announce the availability of the slides). In addition to presenting and several briefing meetings, we also recorded several new TechTalks for both IT professionals as well as channel professionals on a wide range of topics from SMB to enterprise.

In addition to presenting at Storage Decisions, I was also the key note speaker at the Storage Strategies event for channel professionals where I discussed hot and emerging trends, technologies and opportunities for channel professionals. The event put on by TechTargets channel group including Cathy Gagne, Sue Troy and Colin Steele among many others was sponsored by EMC who presented to the channel audience their diverse solution offerings from VMware to storage and all points in between, NEC whom are now expanding their marketing story and messaging to cover their diverse storage line including the D series, servers and blade systems as well as their clustered hydrastor archiving storage system, Nexsan with their second generation MAID intelligent power management for variable performance and energy efficient storage.

To say that things were hopping in New York this week would be an understatement with the 63rd UN general assembly taking place with past and current U.S. presidents, current candidates as well as countless foreign dignitaries in town among everyone else. At the Hilton New York City
, which was the venue for Stg. Desc, as in previous years when its UN week, the place was crawling with not only storage professionals, vendors and industry media, there were also the broader media covering other people at the hotel for meetings including John McCain and foreign dignitaries, as well as celebrities like Ed Burns who was attending a NY FD/PD fund raiser event while across the street, there were the latest movie from Spike Lee ? Miracle at St. Anna?, and then the new release staring Richard Gere & Diane Lane ?Nights in Rodanthe? premieres took place. All that in addition to industry celebrities including Steve Foskett as well as Curtis Preston and many many others.

Back to Storage Decisions event Once again, the TechTarget folks including Lindsey Mullen, Peter Bochner, Rich Castanga, Nicole Tierney and Carol Sliwa and many others put together an outstanding event with an audience of IT professionals. For a storage focused, non vendor event, Storage Decisions remains the premiere event for non vendor audiences. All sessions were once again very well attended by engaging professionals from a variety of different IT organizations which makes these events fantastic for their interaction with the folks in the trenches compared to some events that are more vendors centric focused.

My talk about Green and Energy Efficient Storage Solutions solutions addressing how to do more with less including energy avoidance and energy efficiency, technologies and techniques was well attended by an engaging audience. Several different approaches to address various energy efficiency were covered and that will be further expanded on in addition to many other topics pertaining to green IT data centers in my new book ?The Green and Virtual Data Center? (Auerbach).

For example, one of the topics covered was energy avoidance using 1st generation MAID from vendors such as Copan or second generation MAID 2.0 and inveiglement power management (IPM) or adaptive power management solutions from vendors on a rapidly growing list including Adaptec, DDN, Fujitsu, Greenbytes, HDS, HGST, NEC, Nexsan and Xyratex among others not to mention all of the vendors who have made statements of direction or have upcoming solutions soon to be delivered.

In addition to IPM and MAID based solutions, tape and other off-line mediums including removable hard disk drives from vendors including EMC/Iomega, Fuji Film, IBM, Imation, Prostor, Quantum, Sony, SpectraLogic and Sun among others where the metric for idle or in-active data and storage is how much capacity per unit of energy per given configuration and footprint.

Another category coveted was boosting energy efficiency for active applications and data where the metric is doing more IOPS, bandwidth, messages or emails, files or other transactions or activity per watt of energy using either RAM or FLASH SSD, or, using fast energy efficiency disk drives with vendors that include among others 3PAR, BlueArc, Curtis, Dell, DotHill, Infotrend, EMC, Fujitsu, Gear6, HDS, HGST, HP, IBM, Intel, LSI, NEC, NetApp, Samsung, Seagate, Solid Data, STEC, Sun, SGI, TMS and Violin.

There are also the high capacity storage solutions for bulk storage where the metric is amount of capacity per watt of energy in a given footprint which is basically everyone in the industry that supports high capacity SATA disk drives not to mention the bulk and clustered storage vendors that do more with less.

Then there is the business benefits of data footprint reduction (archive, compress, dedupe) and space optimization vendors for storage and networking ranging from Asigra, Brocade, Cisco, Datadomain, EMC, Exagrid, Falconstor, HP, NetApp, Ocarina, PKzip, Quantum, Riverbed, Sepaton, Silverpeak and Storwize among others not to mention tiered storage among other related hardware, software and management topics. Also covered where various other infrastructure resource management (IRM) topics including performance and capacity planning, space optimization, configuration and use of tools and techniques including virtualization for emulation, aggregation or consolidation as well as for management abstraction and transparency not to mention the usual thin provisioning and use of different RAID levels to boost energy efficiency themes.

In addition to my green storage talk, I also presented on Clustered Storage(aka grid if you prefer) solutions for block and file, on-line active primary to secondary or off-line and near-line for backup and archiving solutions as well as emerging bulk storage solutions for web 2.0 or other instances where large amounts of data need to be stored on-line that in the past would have been archived for example fixed content reference data, web and research material, medical records or other images as well as social networking and entertainment media. Some of the vendors covered in this session included 3PAR, Amazon, BlueArc, Dell, EMC, Exagrid, Exanet, HP, IBM, IBRIX, Isilon, Lefthand, NEC, NetApp, Panasas, Permabit, Redhat and SGI among others.

After a busy couple of days, on the way to the airport the other day while stuck in traffic in busy metropolis of New York City (NYC) where I was flying next to the wide open Midwest spaces of Cedar Rapids Iowa for a key note speaking engagement, a thought that came to mind was, John Carpenters ?Escape from New York? starring Kurt Russell as ?Snake Plissken?.

Well, like ?Snake Plissken?, I made it to the airport in time for my flight to the wide open expanse of the Midwest and Cedar Rapids Iowa and then finally back home, what a week of diversity, however it was a great week.

Thanks too all those who attended and participated in the various events this past week, it was great to meet so many new people as well as reacquaint with others or put a name and face together for so many others. I look forward to seeing and hearing from you all again soon and remember to keep an eye out for my new book, ?The Green and Virtual Data Center? (Auerbach) that you can beat the holiday shopping rush and order now at Amazon.comas well as many other fine venues around the world.

Intelligent Power Management (IPM) and second generation MAID 2.0 on the rise

Storage I/O trends

In case you missed it today, Adaptec announced that they are the 1st vendor “This Week” to add support for Intelligent Power Management (IPM) to their storage systems. Adaptec joins a growing list of vendors who are deploying, or, who are program announcing some variation of IPM and second generation MAID 2.0 ability including support for different types of tiered disk drives including various combinations of Fibre Channel and SAS as well as SATA.

As a quick refresh, Massive or Monolithic Arrays of Idle or Inactive Disks (MAID) was popularized by 1st generation MAID vendor Copan who spins down disk drives to avoid energy usage. One of the challenges with 1st generation MAID is the poor performance by being able to only have at most 25% of the disk drives spinning at any time to transfer data when needed.

This is a balancing act between achieving energy avoidance and associated benefits vs. maintaining performance to move data when needed particularly for large restoration to support BC/DR or other purposes. Granted, 1st generation MAID systems like those from Copan while positioned as alternatives to high-performance disk storage systems to amplify potential energy savings on one hand, or, to put as an alternative to magnetic tape by providing random restore capability. The reality is that 1st generation MAID systems are finding their niche not for on-line primary or even on-line secondary storage, nor as a direct replacement for tape or even disk based libraries to support large-scale BC/DR, rather, in a sweet spot between secondary and near-line disk libraries and virtual tape libraries with a target application of very infrequently accessed of data.

Second generation MAID, aka MAID 2.0 is an evolution of the general technologies and capabilities extending functionality and flexibility while addressing quality of service (QoS), performance, availability, capacity and energy consumption using IPM also known as Adaptive Power Management (APM), dynamic bandwidth switching or scaling (DBS) among other names. The basic premise is to add flexibility building on 1st generation characteristics including data protection, resiliency and pro-active part or drive monitoring. Another basic premise of IPM. and MAID 2.0. solutions is to allow the performance and subsequent energy usage to vary, which is to cut the amount of performance and energy usage during in-active times, yet, when data needs to be accessed, to allow full performance without penalties for energy savings.

Second generation MAID solutions can be characterized by multiple power saving modes as well as flexible performance to adjust to changing workload and application needs. Another characteristic is the ability to work across different types of disk drives including Fibre Channel, SAS and SATA as opposed to only SATA drives found in 1st generation solutions as well as for the IPM or MAID 2.0 functionality to exist in a standard storage system or array instead of in a purpose-built dedicated storage system. Other capabilities include support for more granular power settings down to a RAID group or LUN level instead of across an entire array or storage system as well as support for different RAID levels among other features.

Examples of vendors who have either announced product or made statements of direction with regard to MAID 2.0 and IPM enabled storage systems include:

Adaptec (Today), Datadirect, EMC, Fujitsu, HDS, HGST (Hitachi Disk Drives), NEC, Nexsan, and Xyratex among others on a growing list of solutions.

For applications and data storage needs that need good performance and QoS over a range of changing usage conditions to balance good performance when needed to efficiently get work done to boost productivity, while saving or avoiding energy when little or no work needs to be done, take a look at current and emerging IPM and MAID 2.0 enabled storage systems as part of a tiered storage strategy to discuss power, cooling, floor-space and EHS (PCFE) related issues.

Closing the Green Gap – Green washing may be endangered, however addressing real green issues is here to stay

Storage I/O trends

Here’s a new article I wrote that just appeared over at Enterprise Storage Forum called Closing the Green Storage Gap.

Not all ‘green’ IT solutions or messages are created equal. Regardless of political views, the reality is that for business and IT sustainability, a focus on ecological issues and more importantly, their economic aspects cannot be ignored.

There are business benefits to using the most energy-efficient IT solutions to meet different data and application requirements. However, vendors are busy promoting ‘green’ stories and solutions that often miss where IT organization challenges and mandates exist. This article examines the growing gap between green messaging, or ‘Green Wash,’ and how to close the gap and enable IT organization issues to be addressed today in a way that sustains business growth in an economic and ecologically friendly way.

Have a read and a good weekend.

Ok, nuff said.

Green, Virtual, Servers, Storage and Networking 2008 Beijing Olympics

Storage I/O trends

How about those opening 2008 Beijing Olympic ceremonies on NBC last night?

If you were like me, I had my DVR capture the event while out enjoying the nice August evening with some friends doing some relaxing and fishing (we did catch and release fish!) on the scenic St. Croix river.

John Nelson with a small mouth bass caught and released on the St. Croix River During 2008 Beijing Olympics
Fishing while DVR records 2008 Olympics

John Nelson with a northern pike (swamp shark) caught and released on the St. Croix River During 2008 Beijing Olympics
Fishing while DVR records 2008 Olympics

A young bald eagle seen during fishing on the St. Croix river during opening of 2008 Olympic games
A young bald eagle seen during fishing while DVR records 2008 Olympics

The reason I bring up the Olympics, servers, storage, networking, virtualization and green topics are a couple of themes. One being all the news and content available to keep track of what is happening with the games taking place all of which is being stored on servers, storage and relying on networks to access the rich media and unstructured data via the web or traditional media. The 2008 summer games are also being described as the on-line and virtual olympics. The amount of storage being used to store digital data from the 2008 Olympics for later playback, which then gets recorded on DVRs if not watched in real-time is staggering as are the number of servers and networking capabilities being used. In addition to the video, audio, still photos, text and blogs, then there are the security cameras in Beijing generating massive amounts of digital data.

For those who track or keep an eye or ear open towards data and storage management, the amount of data that continues to grow and number of copies that get created should be a familiar theme. Of course, you would then have heard that the magic elixir is to simply de-dupe everything. That is reduce your data footprint by eliminating all of those extra copies however easier said then done, especially when a copy of the games is being transmitted and saved to millions of DVRs or other forms of data storage servers around the world.

For the time being, I prefer that my DVR support more usable storage capacity and real-time compression so that I can keep more copies of my favorite shows and of course the Olympics all in HDTV, which of course chews up storage space faster than a highly animated PowerPoint slide deck from your favorite vendors most recent, or, upcoming product announcements.

The other theme is in addition to being Olympic time, as well as late summer here in the northern hemisphere or winter for our friends in the summer hemisphere, its also pre-briefing and early product announcement time for the barrage of fall server, storage, networking, I/O, software, virtualization and green related solutions. So far, Im not sure if its the Olympics or what, however the bait line on the upcoming announcements and briefings include the tags “Industry First”, “Industry Unique”, “Only Vendor”, “Only Product”, “Revolutionary”, “First Vendor” or “First Product”, “Fastest”, “Largest”, “Greenest” among other interesting spins and twists that would even make an Olympic gymnast dizzy.

So enjoy the Olympic , keep those hard disk drives in your DVR cool while managing the usable capacity and watch for more gold medal attempts both from Beijing, as well as from your favorite IT vendors coming to a podium to you soon with their upcoming announcements, some of which may be award winning. Also check out www.greendatastorage.com which is now also pointed to by www.thegreenandvirtualdatacenter.com that has a new look and feel as well as some updated content with more on the way.

Missing Dedupe Debate Detail!

Storage I/O trends

The de-dupe vendors like to debate details of their solutions, ranging from compression or de-dupe ratios, to hashing and caching algorithms, to processor vs. disk vs. memory, to in-band vs. out-of-band, pre or post processing among other items. At times the dedupe debates can get more lively than a political debate or even the legendary storage virtualization debates of yester year.

However one item that an IT professional recently mentioned that is not being addressed or talked about during the de-dupe debates is how IT customers will get around vendor lock-in. Never mind the usual lock-in debates of whose back-end storage or disk drives, whose server a de-dupe appliance software runs and so forth.

The real concern is how data in the future will be recoverable from a de-dupe solution similar to how data can be recovered from tape today. Granted this is an apple to oranges comparison at best. The only real similarity is that a backup or archive solution sends a data stream in a tar-ball or backup or archive save set or perhaps in a file format to the tape or de-dupe appliance. Then, the VTL or de-dupe appliance software puts the data into yet another format.

Granted not all tape media can be interchanged between different tape drives given format, generations and of course using the proper backup or archive application to un-pack the data for use. Probably a more applicable apple to oranges comparison would be how will IT personal get data back from a VTL (non de-duping) disk based storage system compared to getting data back from a VTL or de-dupe appliance.

Today and for the foreseeable future the answer is simple, if your pain point is severe and you need the benefits of de-dupe, then the de-dupe software and appliance is your point of vendor lock-in. If vendor lock-in is a main concern, take your time, do your homework and due diligence for solutions that reduce lock-in or at least give a reasonable strategy for data access in the future.

Welcome to the world of virtualized data and virtualized data protection. Here?s the golden rule for de-dupe and that is like virtualization, who ever controls the software and management meta data controls the vendor lock-in, good, bad or in-different, that?s the harsh reality.

For the record, I like de-dupe technology in general as part of an overall data footprint reduction strategy combined with archiving and real-time compression for on-line and off-line data. I see a very bright future for it moving forward. I also see many of the heavy thinking and heavy lifting issues to support large-scale deployments and processing getting addressed over time allowing de-dupe to move from mid markets to large-scale mainstream adoption.

Now, back to your regularly scheduled de-dupe debate drama!

Cheers

Do Disk based VTLs draw less power than Tape?

The tape is dead debates rage on as they have for a decades which make for good press and discussion or debate during slow times, similar to coverage of what Britney Spears or Paris Hilton are or are not wearing.

In the on-going debates and Greenwashing of what technology or vendor is greener to prevent global warming, some recent tape is dead flare-ups have occurred including one hinting that tape libraries can draw more power than a disk based VTL with de-dupe are discussed over on Tony Pearson of IBM fame blog site as well as Beth Pariseau of TechTarget StorageSoup site.

I posted some comments on those sites along along with a link to a StorageIO Industry Trends and Perspective report titled “Energy Savings without Performance Compromise” as an example (look for an updated version of the comparison charts in the report in the not so distant future). The report looks at how different storage tiers including on-line disk, MAID, MAID 2.0 and tape libraries vary to address different PCFE (power, cooling, floor-space, environment) issues while supporting various service levels including performance, availability, capacity and energy use.

Additional related material can be found at www.storageio.com and www.greendatastorage.com including the Industry Trends and Perspective Report Business “Benefits of Data Footprint Reduction in general covering archiving, compression (on-line and off-line) along with de-duplication

StorageIO Spring Keynote and Speaking tour V2.008

Several new keynote and speaking engagements involving myself have been added to the StorageIO events page including among others:

April 8th, 2008 – SNW Orlando FL
Beyond Green-Wash:
IT Data Center Power, Cooling, Floor Space and Environmental (PCFE) Topics and Trends V2.008
This talk will move past what are the issues and reasons for going green and get right to the point of what you can do today leveraging various technologies, techniques and best practices to address PCFE and green environmental issues including EHS, low power and economic sustainment in an environmental friendly manner as well as what to include in a long term green strategy for your data center.

Chicago, May 13th-15th – StorageDecisions
Clustered Storage:
From SMB, to Scientific, to Social Networking and Web 2.0
The growth of structured and unstructured data continues at an explosive rate in most environments resulting in a constantly expanding data footprint requiring data and storage management resources. Similarly, the relative ease of use of NFS and Windows CIFS file sharing based storage, also known as Network Attached Storage (NAS), has led to a proliferation of NAS and Windows file servers which are not all that different from how the ease of use of personal computers (PCs) resulted in desktop and server sprawl. With the focus of many IT organizations today to do more with less, or, do more with what you have, clustered storage and clustered file serving have become a popular option to support modular, scalable and flexible growth. Clustered storage including clustered file serving, grid and web 2.0 based storage solutions are no longer confined to the specific high performance scientific applications they are commonly associated. Clustered storage serving is commonly being deployed to support a wide diversity of applications including commercial, entertainment or media, Web 2.0 and social networking along with grid, cloud and traditional scientific needs.

This session takes a look at among other topics:
? Look at what different clustered storage vendors are claiming and how their solutions differ
? Fact vs. Fiction, Myths and Realties of clustered storage
o Grid vs. Clusters, Cluster vs. Grid, what?s the differences
o Clustered storage is only for ultra large environments like Google
o Clustered file serving is only for high performance (HPC) environments
o SMBs and bulk storage applications can not benefit from clustered storage
? What are the caveats to be aware of when deploying clustered storage?
? What are some emerging trends and solutions to keep an eye on for clustered storage
? What are some questions that some vendors do not want you to ask about their solutions!

Green and Environmental Friendly Storage:
Practical Ways to Achieve Energy Efficiency
Green is in-and every storage vendor out there has a green story to tell. Despite the vendor and industry hyperbole about the environmental benefits of their products, there are still no standard metrics by which to measure and compare power consumption or energy efficiency claims. The challenge is sorting out and closing the gap between vendor green messaging and IT data center issues including power, cooling, floor space and other environmental topics including RoHS and e-waste disposal. This session looks at several practical techniques and technologies that you can leverage today to achieve an energy efficiency data center to sustain business growth in an economical and ecological friendly manner.

Topics that will be covered include among others:
? How truthful are vendor claims and what is ?Green wash?
? Facts and Fiction, Myths and Realities:
o Storage is cheaper to buy than to power
o Power avoidance vs. energy efficiency
o Are Solid State Devices (SSD) the silver bullet?
o Dedupe vs. Archive vs. Compression vs. Consolidation
? What?s real and achievable today, what are your options?
? Measuring and determining energy efficiency with emerging metrics
? How to do more with what you have and avoid forklift upgrades
? Who is the ?Greenest of them all? and where to learn more

I will also be keynoting at several TechTarget seminar series events around the U.S. including
