Kw Per Rack

At plate rating the total watts per ft 2 is about 668 watts when the facility is only capable of running at 108 watts per ft 2.

Kw per rack. The four definitions that use w ft2 or w m2 are ambiguous unless accompanied by a clear. Based on this cost curve this paper proposes that the optimal average density per rack is 5 8 kw per rack. By 2016 that had been turned on its head 10 to 12 kw per rack was considered high density. The right methodology to develop a good estimate depends on how much you know about your existing operation and its probable growth trends.

25 data centers benchmarked. Eetd divrev 2004 page 3 the data center challenge data centers 15 40x the energy intensity of typical office buildings a single rack of servers can be 20 kw 17k per year at 10 kwh per rack hundreds of racks per center where are the opportunities. Ten years ago the standard for power density was in the range of 4 5 kw per rack. To illustrate this point consider the fact that 2 to 4 kw per rack was once considered high density.

Fast forward just a couple of years and you find that things have changed once more. It cost 68 percent less to support 1kw in facilities with average rack density of 8 5kw than in facilities with average rack density of 4 5kw. Low up to 4kw per rack cabinet medium 5kw to 8kw per rack cabinet high 8kw to 15 kw per rack cabinet extreme over 16kw per rack cabinet average. After entering in all your variables you can now see that we have finally calculated amps per server kw per rack total kw and total watts per ft 2.

Deploying the it equipment at lower densities is much more costly per watt and deploying. Download the report on the study in full here. Immediately we see a problem. 5 kw per rack this definition is computed on a per rack basis which eliminates much of the variation when defining power density.

The researchers also found that data center cost per kw decreases as rack density increases. Today this has progressed to a low density in the range of 8 10 kw per rack an average power density of 15 16 kw per rack and even more ambitious providers that go above 20 kw per rack. Facebook data centers huge scale at low power density. The baseline kw of heat output per rack varies widely depending on type and density of equipment and can be anywhere from 4 kw 12 kw or more per rack with some experts estimating that the rise of high density environments and designs for future equipment will result in an output of 30 50 kw per rack.

In the past enterprise data center infrastructures were widely expected to increase rack consumption targeted at 30 kw on average.
