The Chicago site is powered by 12 utility feeds from 4 substations in a redundant configuration. The block redundant architecture is configured so that a single 2 MW catcher buss supports four (4) 2 MW primary busses. Each primary buss has two (2) 1 MW unity power factor UPS systems that are configured in a distributed redundant architecture. Three (3) 500 kVA/kW UPS units make up a single N+1 1 MW UPS system. Power is then distributed to PDUs located on the data hall floor.
A 1,400 Ton water cooled chilled water plant is utilized for heat rejections. Chilled water is fed via dual risers to each IT floor to create a chilled water loop on each floor. The chilled water is fed to CRAH units configured in an N+4 topology located on the data hall floor. A waterside economizer is utilized in the chilled water plant to maximize efficiency throughout the year, yielding an annual PUE of 1.4.
