System and Method of Dynamic Cooling Provisioning among Cooling Zones

Disclosed is a method and system for boosting performance of a power-oversubscribed system consisting of multiple cooling zones by explicitly determining cooling shifting along with power shifting between cooling zones, with over-

provisioned cooling

capacity for each cooling zone.

In accordance with the method and system disclosed herein,

power supply for such a system is oversubscribed and is share

d

among multiple cooling zones. Both compute components and cooling components use the same source of power supply in such a system.

The system employs an over-

provisioned cooling componen

t

(for example, oversized fan, serial/

parallel fan pairs, etc) in each

cooling zone. Prior arts design each cooling zone's cooling capacity independent of other cooling zones in the same system and

do not have a significant amount of cooling over-

provisioning in each cooling zone. For a power oversubscribed system, due to

power capping and power shifting among cooling zones,

prior arts prevent significant power shifting from one zone to anothe

r,

due to insufficient additional cooling capacity for each zone.

With the disclosed method and system, because of the over-

provisioned cooling capacity in each cooling zone, shifting

significant power from computing components in one zone to computing components in another zone is made possible. Cooling

power also shifted accordingly from one zone to anothe

r, within t...
