Alternating phase power distribution technology from Server Tech is one of my favorite subjects. It has benefits that extend well beyond the electrical distribution world. In fact, it is one of the few power products whose secondary benefits meet and sometimes exceed the fundamental purpose of a three-phase distribution product. I discussed it in a previous post.Read More
In the world of rack-mountable power distribution, the term high density is so hot right now. After all, it is no secret to anyone in the industry that the business that takes place within the four corners of a rack has been warming up faster than a Jane Fonda workout video.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:
An increasingly common conversation within the data center industry revolves around the need for flexibility balanced against the desire to save money. It’s getting harder to make the case that your enterprise needs more land for capacity expansion. At the same time, 27 percent of data center costs are for power, according to a DCD report in 2014. As you can imagine, the result has been a drive for proportionally higher server and power densities across the globe.Read More

Competition is fierce in the global multi-tenant data center market right now. At the midway point of 2015, for instance, the market grew by 4.7 percent. And physically speaking, the market expanded by about 90,000 square meters during the second quarter alone.Read More
