Abstract
Embodiments include a power-efficient failover system. In one embodiment, a primary server is operable at one or more power states and is configured to dynamically generate a backup for the results of n executed program code while in a normal operating state. A redundant server is coupled to the primary server and is operable at the normal operating state or one or more reduced power states. The redundant server is also configured to dynamically receive the backup from the primary server and, in response to a failure of the primary server, to assume the workload of the primary server according to the backup. A controller manages the power state of the redundant server.
