Facebook Kw Per Rack

By 2016 that had been turned on its head 10 to 12 kw per rack was considered high density.

Facebook kw per rack.

Fast forward just a couple of years and you find that things have changed once more. At 28 kw per rack ilm is at the upper limit of what can be cooled with today s computer room air conditioning systems says roger schmidt ibm fellow and chief engineer for data center efficiency. This is now perceived to be increasing forty five percent of companies said they expect average density of 11 kw per rack or higher over the next year according to a 451 survey of 750 enterprise users. The new blade chassis promises to push the boundaries of high density computing to 80kw to 100kw per rack.

To illustrate this point consider the fact that 2 to 4 kw per rack was once considered high density. Average server racks in most data centers use between 4 kilowatts kw and 8 kw of power. Density is finally rising. This white paper analyzes these costs and presents a flexible architecture to accommodate a well specified density and discusses the importance of operational policies in enforcing the specification.

Ten years ago the standard for power density was in the range of 4 5 kw per rack. So rack densities will probably not climb significantly but the amount of compute power. We ve been hearing this for a long time but until recently the average has been 5 kw a rack. Of the rack 500 000 watts 100 racks 5 kw per rack this definition is computed on a per rack basis which eliminates much of the variation when defining 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. 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. All of the definitions for density in table 2 are used in published literature and specifications.

Rack density is growing slightly but on average not to the levels served by direct liquid cooling said dennis vanlith senior director global product management at chatsworth products who said most users average between 8 kw and 16 kw per rack. Average rack power density of at least 5 kw per rack however densities higher than 15 kw per rack show no further relevant savings.
