Patent ID: 8755948

Claim:
A method comprising: at a server rack comprising a plurality rack servers, each of the rack servers comprising a plurality of components and a cooling system, wherein each cooling system is configured to control a flow of fluid coolant through the respective rack server independent from the cooling systems of each of the other rack servers, and each cooling system being configured for: determining whether a temperature of each of the plurality of components of the respective rack server is less than a predetermined threshold value; in response to determining that the temperature of each of the plurality of components of the respective rack server is less than the predetermined threshold value: determining whether one of a current work load mode and a planned work load mode for a processor of the respective rack server is one of an overclocking mode and a predetermined workload mode; in response to determining that the one of a current work load mode and a planned work load mode for a processor of the respective rack server is the one of an overclocking mode and predetermined work load mode, increasing a flow of the fluid coolant through the cooling system of the respective rack server; determining whether a state of the respective rack server is one of an idle state and a sleep state; in response to determining that the state of the respective rack server is one of an idle state and a sleep state, decreasing a flow of the fluid coolant through the cooling system of the respective rack server; determining whether a command received by the respective rack server is one of an open command and a close command; in response to determining that the command received by the respective rack server is an open command, increasing the flow of the fluid coolant through the cooling system of the respective rack server; and in response to determining that the command received by the respective rack server is a close command, decreasing the flow of the fluid coolant through the cooling system of the respective rack server.
