How-to guides are downright handy for tackling daunting projects, such as deploying a new BPM (business process management) solution or building a birdhouse (one of those really fancy ones with indoor plumbing).
One of the most daunting tasks that companies face today is figuring out how to wring greater energy efficiency out of their datacenters. Certainly, many vendors are ready to step up and demonstrate where their respective products fit into the power-saving puzzle. But there's something to be said for a vendor-neutral blueprint to plan the overall task.
That all is a wordy lead-in to pointing you to a new report -- available as a free download -- released today by Emerson Network Power. It's titled "Energy Logic: Reducing Data Center Energy Consumption by Creating Savings that Cascade Across Systems," and it's an impressive piece of work, outlining ten interrelated technology strategies that comprise a holistic approach to improving datacenter energy efficiency by as much as 50 percent, according to the company. And as I noted, it's free.
For a little background, Emerson has coined the term "Energy Logic" in this report, a strategy which, according to the company, "centers on 'the cascade effect' by which one watt saved at the processor level can save an average total of 2.84 watts in energy consumption."
The report starts at the server component level, outlining the benefits of low-power processors. "Independent research studies show these lower-power processors deliver the same performance as higher power models," the report says. "In the 5,000-square-foot datacenter modeled for this paper, low-power processors create a 10 percent reduction in overall datacenter power consumption."
Next up: power supplies. The report notes that most power supplies found in servers are working at around 72 percent effiency -- yet "best-in-class power supplies are available today that deliver efficiency of 90 percent. Use of these power supplies reduces power draw within the data center by 124 kW or 11 percent of the 1127 kW total," the report says.
