LAS VEGAS -- While few doubt the importance of maximizing the energy efficiency of their corporate data centers, executive vice president of datacenter technology for Las Vegas-based Switch, Mark Thiele's talk atInterop this week showcased just how much companies might still bemissing. INTEROP: Interop panelists debate future of physical WAN optimizers He cited five big areas to focus on including: 1. Understand airflow Thiele says that basic thermodynamics makes the raised floor modelless efficient than it could be. Given that cold air tends to sink,while warm air tends to rise, he asserts, "why would you push coldair from the bottom?" 2. Get rid of zombie servers If there are legacy machines still running in the data center andnobody knows they're there, do they still draw power? Absolutely.Thiele says that taking careful inventory can reveal "zombieservers" that companies might not even know they still had. 3. Efficiency at the cost of capacity isn't really efficiency While it's tempting to work as hard as possible on minimizing powerdraw, teams that slash their capabilities in order to do soseverely reduce the potential return on investment that they canprovide. "IT's opportunity is to help the business make more money.... If using more power to do it makes sense, then you should bedoing it," Thiele says. 4. Don't sweat the humidity/temp... More recent generations of data center equipment don't need to bekept quite as cold as their predecessors, Thiele asserts. "As longas most of your gear is less than four years old, take a wild leapand go to 75 degrees," he advises. "Open up your bandwidth forhumidification to 15 and 70, instead of 45 and 60, or somethingtight like it's been historically." 5. ...but do sweat the small stuff "You can't touch the paint on the walls without potentiallyaffecting the performance of your data center," according toThiele. Everything from the size of the doorways to the height ofthe floors and the presence (or, hopefully, absence) of dust in theair can be a major factor in determining how efficiently a facilityoperates. Thiele, it should be clear by now, is very serious indeed aboutdata center power efficiency. On one occasion, "I actually left my wife and daughter at acampsite in Point Reyes," in order to drive an hour and a half tofix a problem, he says.
