ENTERPRISE DATA CENTER MAINTENANCE AND CAPEX FORECAST ESTIMATOR

Designed Capacity of the Data Center

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

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 shows an inverse relationship between rack density and annualized PUE.

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

UPS batteries are typically sized to allow ride through to generator start but may also consider a data center user's risk profile.

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

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

Power Usage Effectiveness (PUE) = (Total Facility Energy) / (IT Equipment Energy). Uptime institute's 2021 survey indicates that respondents' global average annualized PUE in 2021 was 1.57 versus an average PUE of 1.98 in 2011.
