ABSTRACT:
Disclosed herein is a server system having a plurality of computer systems and a liquid cooling system. The computer systems are capable of operating in a first mode of operation at a first operating speed and a first temperature. The computer systems are further capable of operating in a second mode of operation at a second operating speed and a second temperature. The server system switches from the second mode and the first mode in response to a request for processing services rising above a first threshold. The server system further uses a cold battery to store coolant during times of low demand and releases coolant from said cold battery when the system switches to the first mode.
