Data Centre Kw Per Rack

Specifying the future undefined rows with a high peak density value of 15 kw provides.

Data centre kw per rack.

The focus on density is timely. In the past enterprise data center infrastructures were widely expected to increase rack consumption targeted at 30 kw on average. Today the average power consumption for a rack is around 7 kw depending on the data center you re looking at. You ve already done the legwork for this.

Density without yet specifying the details of the rows then the overall average data center. Some data centers may actually hit 20 or more kw per rack. Density can be computed to be 2 7 5 7 3 7 4 5 4 5 4 5 4 5 41 3 7 kw per rack. Data centers that plan for the forecasted extreme densities will likely run out of it floor space well before they use up their power and cooling resources.

The researchers also found that data center cost per kw decreases as rack density increases. Range of 3 5 kw per rack. Understandably the higher the power density the more heated the rack will be and more resources need to be provided for cooling. Next divide the number of server watts by 1 000 to get kw per server.

The 2020 state of the data center report found that the average rack density increased by nearly an entire kilowatt kw from the previous year jumping to 8 2 kw per rack up from 7 3 kw in the 2019 report and 7 2 kw in 2018. Afcom segments data center density into four categories. Low up to 4 kw per rack medium 5 kw to 8 kw high 8 kw to 15 kw and extreme more than 16 kw per rack average. 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.

Afcom describes data center size by compute space and density by measured peak kilowatt kw load. For the majority of data centers stranded power and cooling capacity is very costly. 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. Throughout the industry this expectation has largely not been met and power consumption per rack is typically kept at the medium to high range.

After calculating the kw per server you will then multiply that by the number of servers per rack to get your final data center maximum kw per rack. To calculate total kilowatts needed you want to multiply the number of servers per rack by kw per server.
