Hi I’m Don Atwood, author of the newly released white paper and video that discusses our proof of concept (PoC) that tested cooling our Data Center with outside air. The topic of humidity control and if this would work in an ultra high humid climate keeps coming up. Most OEM spec’s allow for a wide range of humidity and it’s our belief that this cooling methodology could be used almost everywhere globally. Our only uncertainty comes around trying this near the ocean with high levels of salty corrosive wet air. We know it would negatively affect the servers at some point but the question is how quickly and is it within our refresh timetable. During a trip to ASIA last week I discussed trying a small scale “near the ocean” PoC to test this theory.. Does anyone thing this would add value to your company?

My daughter recently brought home from school a photocopy of the lyrics of Jack Johnson’s “The 3 R’s” (from the Curious George soundtrack), which encourage us to “Reduce, Reuse, Recycle”. This struck me as relevant in some of the recent discussions I have been having about Greenwashing in the Data Center.

A fair amount of our data center strategy deals with driving down costs. We’re trying to spend less money to deliver the same or better results. Along the way, we find opportunities to be green. While I would love to have more meetings that start out with the question of “what can we do to help the environment?” rather than “what can we do to cut costs?”, we do talk about both. This is somewhat similar to consumer-oriented eco-efforts, encouraging people to save the world while saving money: unplug electronic devices when they're not being used, replace your appliances with more energy-efficient ones, etc. I don't know of many people or organizations who wouldn't like to spend less money, and when we can help the environment at the same time it's win-win.

Which brings me back to the song lyrics. Our cost-cutting measures tend to be related to at least two of the three “R’s” – reducing what we consume, many times by reusing what we already have. I’ll spend my next few posts exploring this a bit further, giving some specific examples of our cost-savings initiatives that ultimately contribute to a greener data center and IT infrastructure.

Happy Earth Day...

Is hypervisor based server virtualization basically a “useful” tactical consolidation “play” or does it form the basis for much more? For several years, server virtualization has been used with good success by many organizations to consolidate legacy workloads as well as to cost-effectively provision test and development virtual machines (VMs). During the same timeframe, there has been significant discussion pertaining to “the datacenter of the future” – a centrally managed “dynamic” datacenter where resources will be dynamically assigned “on demand” to workloads in an agile manner thereby allowing the datacenter operations teams to quickly adapt to fluctuating demands for compute resources. So, “where is the connection?” you ask.

The recently concluded VMworld 2007 may offer some hints. At that conference, VMware Chief Scientist, Dr. Mendel Rosenblum, demonstrated some key capabilities that show where compute virtualization is headed in its evolution to becoming the “datacenter operating system” of the future. Dr. Rosenblum demonstrated “storage live migration” and “lockstep VMs”. Transparent migration of storage “owned” by a VMs from one disk (LUN) to another (potentially on a different storage frame) without impacting application availability was demonstrated in the first demo. He also demonstrated the ability to transparently failover an executing VM to a “secondary” VM – on another host - that has been executing in lockstep with the primary VM! If you did not have a chance to see Dr. Rosenblum’s keynote, a webcast is still accessible here.

Per the VMworld demonstrations mentioned above, the hypervisor based virtualization capability and upcoming hardware assists for virtualization in combination with a “compute virtualization manager” that collectively enable policy-based management of the datacenter including virtualization hosts, VMs, storage is well on its way to evolving to the dynamic “Datacenter OS” of the future. This powerful Datacenter OS of the future – evolved from today’s “tactical” virtualization capabilities - will dynamically manage compute, memory, power, storage and network resources of the Datacenter in an automated, highly efficient manner. Pre-packaged applications in portable VMs will be landed on these dynamic datacenters in a flexible and agile manner.

While the hypervisor based virtualization based evolutionary path may not be applicable to highly specialized datacenters (e.g., HPC), its applicability to Business computing environments is clear. Am I oversimplifying and underestimating the technical challenges (security and scaling to name a few) along this evolutionary path? Probably. Am I glossing over the organizational and business process related challenges? Almost certainly. On the other hand, are all the major building blocks like efficient hypervisors, virtualization hardware assists, VM live migration, storage live migration, power management, record and replay, lockstep VMs…) successfully prototyped or better (in production)? The answer is an emphatic “Yes”. Do you agree or do you forsee insurmountable barriers that will thwart attempts to evolve the virtualization capabilities of today into the dynamic data-center of the future along the lines suggested by the ground-breaking capabilities demonstrated at VMworld? Either way, I’d really like to hear your perspective.

Like most other companies these days, Intel is facing a growing demand for computing resources. As a result, our computing costs are going up along with that demand. All of these issues prompted us to take a hard look at our data center strategy, to see where we could make it more efficient.

Therefore, we’ve launched into a significant undertaking. We’ve started the process to End of Life (EOL) or consolidate our data centers down to just eight strategic locations. This effort is planned to take us eight years, but we’re working to pull this in sooner. This initiative enables us to reduce costs, improve server and storage utilization, create higher density & more energy efficient data centers, and allows us to keep pace with our company’s rapid rate of innovation. The effort could deliver up to $750M in Net Present Value. View my video blog for more information.


I would be interested to hear your comments, questions and have you share with us what your company is doing to drive efficiency within your data centers.
