Early each year we post a “Top Ten” list of critical technologies or trends on the minds of CIOs. For this post, we leverage Gartner survey results done late in 2010, as a starting point. Last month, Gartner delineated its top 10 technologies for 2011 that will give technology execs the most bang for their buck. In this list, there are items that we’d expect to see on a 2011 Top Ten list, some that are a surprise, and some notable omissions.
Let’s get right to it:Details
Power Usage Effectiveness (PUE) is a metric created by The Green Grid to determine the energy efficiency of a data center. PUE is a ratio, with overall efficiency improving as the quotient decreases toward unity. In other words, PUE measures the extra power needed to power, cool, protect, and manage the IT load in a data center.
Since the issuance of PUE, many data center managers are under pressure to drive the PUE of their facility lower. The notion of driving energy efficiency is a noble one, but the drive toward a PUE target is not a pragmatic endeavor.
PUE should be viewed as a tool, not a destination. While the PUE is based upon very simple math, PUE comparisons are very difficult. In fact, it’s dangerous to compare PUE values between data centers because so much depends upon where (with respect to the facility infrastructure) PUE readings are taken, as well as which data center energy components are included in the scoring. There are simply too many variations from facility to facility and from operator to operator to know if one has a true “apples to apples” comparison.Details
Data Center Dynamics is always a great reading on the pulse of the industry, and the December, 2010 conference in Richardson Texas set the sounding board for contemporary developments in modularity and efficiency in data centers. The following are thoughts and reflections on the discussions held during the conference.
Data Center Design: From Traditional to the Future
The shift in computing paradigms over the past fifty years has, to some extent, followed generational timelines. Early in the computing evolutionary timeline, computing and storage existed in a centralized in a consolidated data processing footprint, optimized for efficiency driven by high cost of systems. End users reached their data and application through thin client devices. The upfront costs for hardware and software were very high.Details
This morning I was reading a short piece by Gary Beach, Publisher Emeritus of CIO Magazine in which he asks if he’s “certifiably nuts” for encouraging broad-based, state-administered technology certification programs. The short answer from me- no, not really. I would though, like to support the spirit of Gary’s call with my own encouragement.Details
I’ve just returned from a meeting in Washington, DC in which we were assessing training material for certification on the new BICSI data center design best practices. Along with the fact that I’ve been approached lately with a number of site security assessment requests, it was interesting to review the guidance on data center location.
We have discussed data center location guidelines in this forum before, and with BICSI-002’s alignment with TIA-942, the contribution has been to bring guidance into a contemporary framework. We bring this up again because while such guidance for mission critical facility location with respect to environmental and human threats has been on the shelf for a long time, chances are very good that your data center is not in good standing with respect to these location guidelines.
For the record, we’ll run through the general list of property adjacencies that contribute risk to the site, in concentric fashion beginning with the closest proximity to the site.Details
A very dear friend of mine, Vaughan Merlyn, recently suggested that I re-read Eric Raymond‘s book, “The Cathedral and the Bazaar.” It’s been a while since I’ve picked this up and frankly I’d forgotten much of it.
The very first time I read “The Cathedral and the Bazaar” I was working for a company in the open-source software space. At that time, many years ago now, I was relocating my desk from the Cathedral into the Bazaar, and the book offered me valuable cultural perspective. At this writing, nearly 10 years later, the whole open-source versus closed-source dialogue is in quite a different place and it almost feels as awkward to reflect upon open-source development as some sort of alternative to mainstream as it does to think about whether my car is American, Japanese, Korean, German, or Mexican (it’s a bit of all those and it’s just the way it is these days).
My most recent reading of this book though gives me a completely different serving of brain food, for which I’m grateful to Mr. Raymond. I’d like to share a couple of those points with you here.Details
Many of the engagements that we work involve producing the initial conceptual layout for construction of a data center. As a certified design consultant, we draw upon best practices reflected in the BICSI-002 standard, TIA-942, et. al. Even when the raw space with which we’re working is a nice big rectangle, this job can be…Details
As a part of the enterprise IT assessment process, and as a component for articulating the rationale for elevation of IT service capabilities to achieve alignment of IT with the strategic goals of the business, a description of the current level of IT maturity is a beneficial measure. ISACA is a global provider of information,…Details
Our regular readers will understand that we do not routinely report on vendor-specific industry events, but because of the increasing presence of virtualization as a foundational component in enterprise IT architecture, this week’s VMWorld in San Francisco is hard to ignore.
In a press release, VMware revealed a roadmap that is focused on IT services in support of Business. ¬†As expected, there is a lot of focus on the Cloud in this strategy. ¬†Earlier posts in this forum highlight how foundational the Cloud has become in enterprise IT roadmaps. ¬†What is more interesting in this announcement is the focus on IT as a service. ¬†In this post, we are focusing only on the content of VMware’s press release because of its statements about product strategy. ¬†It is recognized that additional color and content apply from the conference more broadly.Details
