Measuring power draw precisely is something other vendors have struggled with. Rival Sentilla at one time used small devices that attached to each piece of equipment and reported power usage via a wireless mesh network. It decided that system was too cumbersome to implement at large data centers, and last year it switched to a software-only system. The new product reads the power draw from metered equipment and then calculates the remaining values with a triangulation system that fills in the blanks like a game of Sudoku. It claims this system is 98 percent accurate.
EnergyCenter may provide less of a granular, real-time view than some other tools, but it's still a good starting point for the many data centers that are not measuring energy use at all, said Jed Scaramella, senior research analyst for servers and energy efficiency at IDC.
"It doesn't have that real-time data, but real-time data is going to cost more and not everybody needs it yet. At the price point they are coming in at, this can be an effective tool that is very easy to deploy," he said.
Viridity sells its product on an annual subscription basis starting at about $25,000. It is available today in North America, and the company is looking for partners to help sell it in Europe. It says it has six customers using the product today.
