Even the EPA missed this one in their recent Report on Server and Data Center Energy Efficiency.
It's Active Power Management: That is, safely and intelligently powering-down unused and/or idle servers, and re-powering them when needed. It's a huge (and obvious) move when you consider that the average server burns-up more than half of its fully-loaded rated power when it's just sitting doing nothing.
Reams have already been written about energy-efficient servers, DC power distribution, improved cooling systems, hot/cold aisles, and of course server consolidation. But they've all missed-the-boat -- until today. And the solution is surprisingly simple.
Regardless of the type of server and type of software, this technology is non-disruptive to the data center. It's also the moral-equivalent to turning off the lights in a room that you're not using. Think of the Thousands of servers that sit idle most of the time in Development/Test, or in a "warm" failover facility.
What's the secret sauce?
- It's the ability to gracefully shut-down software prior to turning off the box, and then ensuring re-start when the box is needed again.
- It's the ability to set policies around application importance and interrelationships, and to be able to communicate directly with the software during a power-cycle.
- It's the ability to do all of this from a hardware- and software-neutral perspective
- And, it's the ability to do this in a way that will please both IT and facilities
All made possible with Cassatt's leading ability to apply sophisticated optimization technology to any problem in the data center. And don't just believe me. Look at what PG&E, Brocade, and IDC are saying. This should help raise-the-bar for energy-efficiency best-practices in the data center.
