HP Modular Cooling System Site Preparation Guide

There are several simple steps to determining the coolant requirements and corresponding
resources necessary for effective implementation of the HP MCS. The flowchart in Figure 15 outlines
the steps and necessary information/resources for each aspect of the implementation.

Cooling Loop Sizing
Sizing the cooling loops can be straight forward based on the planned cooling requirements of
each populated/planned MCS server enclosure. The amount (watts) of heat to be removed from
each component in the server rack should be added together for the total heat to be removed by
the HP MCS cabinet. Table 9 may be copied for documenting individual cabinet calculations.
Calculations should include the equipment installed today and additional equipment planned for
installation over the design life of the system.
