HP Modular Cooling System manual Choosing the best cooling strategy

The HP POD supports HP or any third-party IT equipment that conforms to 19-inch industry-standard mounting and front-to-back air flow. The only requirements at the location of installation are as follows:

•Utility power:

2 x 480 V/3-phase delta, 400 A, 50-60 Hz

•Communications

•Chilled water: Flow rate:

HP POD 2000c; 120 gpm HP POD 4000c; 240 gpm

Maximum inlet temperature: 55º F – 75º F (12º C – 24º C)

HP PODs can be installed inside existing buildings or outdoors. They can be used to expand an existing data center or can become the basis for a new data center.

Choosing the best cooling strategy

We do not recommend a specific cooling strategy as the best strategy for all data center environments. The optimum cooling strategy depends on factors such as facility characteristics, room mapping, power consumed per rack, and server density.

Cooling decisions based on facility characteristics

Table 1 shows a list of facility characteristics and probable cooling strategies.
