AUTOMATED POWER CONTROL POLICIES FOR DISTRIBUTED SERVER POOLS BASED ON APPLICATION-SPECIFIC COMPUTATIONAL REQUIREMENTS

摘要

Power and redundancy management policies are applied individually to the tie rs of redundant servers of an application service such that power is reduced while maintaining a high level of system availability. Servers which are determined to be relatively inactive are moved to a free pool. Certain serve rs of the free pool are maintained in a hot standby state, while others are powered- off or set to operate in a low power mode. During times of high loa d, the servers in the hot standby state can be provisioned quickly into the application service.
