October is already here, which means we’re rapidly approaching the end of the year. Before you know it, the holiday rush will arrive, followed closely by the start of 2018 — which means time is running out to plan your data center’s 2018 power management strategy.Read More
There is still a full quarter to go in 2017, but already it’s been a record-setting year for the U.S. data center industry which has generated more business than ever before.Read More

It’s no secret that data centers are massive energy hogs. As explained in a recent Server Technology white paper, “The Power of Hyperscale Compute,” a typical data centers can be 10 to 100 times more energy-intensive than an office. And altogether, data centers use about 3 percent of the U.S. electricity supply.Read More
For those of you who are working through the issues of remotely managing your data center power, or are thinking about heading in that direction, we have a few pearls of wisdom.Read More

When President Harry S. Truman coined the phrase, “If you don’t like the heat, get out of the kitchen,” in 1942, he was referring to critics of his aggressive use of war contracts in the Second World War. Good advice for politics, perhaps, but not so much for data center management. In fact, when heat becomes an issue in your data center, it’s time to do something about it.
Each kW hour of server power creates and equivalent amount of heat. Over time, this heat can accumulate, impacting server performance. You canmonitor this within the cabinet, zone, and location levels. While servers have been adapted to withstand higher temperatures, computing power is rising, and this is generating more heat. Add on top of this the growth of virtualized servers leading to fewer idling computers, and you have an endless cycle of heat generation.
The fact is that many power and cooling systems can’t efficiently meet the demands of today’s data center. The perimeter-based CRAC units of yesterday were sufficient when rack densities hovered at the 2-4 kW per rack range, but this doesn’t really work in a modern data center.
The two main problems that currently exist are:
