I realized a few years ago that all Data Center challenges can be solved with the sufficient application of money.
Need more computing capability? Buy new hardware. Struggling with hot spots? Purchase supplemental cooling infrastructure. Don’t have enough physical space? Pay to expand the Data Center or lease additional space.
More performance means greater cost, though. Some energy saving technologies buck that trend when compared to conventional facilities, but generally the more capability you want from a Data Center the more it will cost to build and operate.

How long do you expect your electronic gadgets to work for you? Not necessarily how long will devices last before simply breaking, but for what length of time will they usefully perform the functions that you obtained them for?
With technological advances coming faster and faster nowadays – and older systems therefore becoming obsolete quicker and quicker – plus a growing number of devices that have to keep pace with other online systems in order to remain useful, the useful lifespan of our gadgets seems to be shrinking.
A glance around my home office provides a snapshot of how long much of my electronic paraphernalia has been in operation Read More »

Ah, weather – one of life’s multi-purpose tools. Conversation filler (“Quite the weather we’re having.”), alleged indicator of world’s end and source of inspiration for comic book writers to empower heroes and villains alike.
Weather can also be a Data Center’s best friend. Solar energy can be harvested to help generate power, for instance, such as is happening at Cisco’s Data Center in Allen, Texas. (Look for the 100 kW solar array on the right side of the Data Center’s roof.) Wind energy as well. Rainwater can even be collected for cooling system usage or to irrigate landscaping.

I must confess, the first time I heard about virtual desktop infrastructure it made me think of a scene from the 1985 movie Brazil. (The movie is old enough that I trust I’m not spoiling anything here. If it’s sitting in your Netflix queue and you don’t want anything revealed, though, skip the next paragraph.)
In the scene Sam Lowry, the movie’s main character, struggles to work at his too-small desk that adjoins a nearby wall. The desk shifts, and begins to retract into said wall, causing Sam to yank mightily on it in hopes of recovering some usable desk space. After a brief tug of war, he discovers the source of the problem.
Fortunately, that’s not how virtual desktop technology truly works.
This week’s Data Center Deconstructed question raises the issue of how to determine the ratio of physical servers to virtual desktop instances. As my meandering thoughts of Brazil indicate, I’m not your go-to guy for such information. Ashok Rajagopalan, a product manager in Cisco’s Server Access Virtualization Technology Group, steps in to addresses the topic.

What are typical power and cooling densities in a Data Center these days? What do you think they’ll be in the future?
I routinely host Data Center tours at Cisco’s headquarters. During those walkthroughs I often discuss how the densities in our server environments have increased over time. Facilities with 50 to 60 watts per square foot gave way to those of 100 to 120 watts per square foot, which in turn gave way to those of 175 to 200 watts per square foot.
“I’m your density. I mean… your destiny.”
