We' ve mentioned high-efficiency power supplies for desktops and towers. But what about servers, storage systems and appliances?

No fear, companies like ColdWatt are addressing the data center market and trying hard to attain 90-Plus, if such a thing is possible. Today the power supply maker announced that clustered storage vendor Isilon Systems is dropping ColdWatt’s 650 Watt power supplies into their new gear.

According to a press release, here's what swayed Isison:

"Because ColdWatt's power supply is double the power density and significantly higher efficiency than our previous solution, we were able to deliver our new X-Series storage nodes that provide up to 60 percent improvement in throughput for data write and random access while saving approximately 18 percent of overall power consumption," said Brett Goodwin, vice president of Marketing and Business Development, Isilon Systems. "This reduction in power translates to real savings for our customers where they can either lower their electric bill or add more storage with a smaller power footprint in energy constrained environments."

If the graph in this product spec sheet (PDF) is to be believed, efficiency hovers comfortably above that of 80-plus power supplies. Nice!

Thanks Dan!
