INFRASTRUCTURE CONFIGURATION

Actual Critical IT Load

?
Power as read at the UPS output.
kW

IT White Space

?
Square footage of the actual computing space of the data hall not including external support spaces like UPS rooms or equipment galleries.
ft2

Current Power Density

?
A data hall can range from 100 – 300 W/SF. A 2021 survey from the Uptime Institute indicates 36% of data centers operators are below 10kW per rack and 36% of operators are between 10-19 kW per rack. Only 12% of users are above 30 kW per rack. Data also show an inverse relationship between rack density and annualized PUE.

UPS Redundancy

?
Uptime Institute’s 2020 global survey show a shift away from 2N and a shift towards N+2.

2N: 34%
N+2: 16%
N+1: 47%
N: 3%

Generator Redundancy

MECHANICAL TOPOLOGY

Heat Rejection Type

?
In 2018, data centers used 135.5 billion gallons of water

Plant Redundancy

?
Use of availability zones and multisite resiliency has decreased data center cooling redundancy in 2020.

2N: 11%
N+2: 19%
N+1: 65%
N: 5%

Estimated Annualized PUE

?
Power Usage Effectiveness (PUE) = (Total Facility Energy) / (IT Equipment Energy). Uptime institute’s 2021 survey indicates that respondents’ average annualized PUE globally was 1.57 while the average in 2011 was 1.98.
