摘要： Embodiments include a power-efficient failover method. The method includes operating a primary server at a normal operating state in which program code is executed, and dynamically generating a backup of the results of the executed program code while in the normal operating state. The method further includes operating a redundant server at a reduced power state in which less power is consumed than in the normal operating state of the primary server. The workload of the primary server may be assumed according to the backup in response to a failure of the primary server. The power state of the redundant server is managed, including maintaining the redundant server in the reduced power state prior to detecting a failure of the primary server and increasing the power state of the redundant server and assuming the workload of the primary server in response to the failure of the primary server.

摘要： Embodiments include a power-efficient failover system and method. In one embodiment, a primary server operating in a normal operating state is configured to dynamically backup device states or transaction logs. A redundant server coupled to the primary server in a failover cluster is operated at a reduced power state. The redundant server dynamically receives the backup from the primary server and is elevated to a normal operating state in response to a failure of the primary server. By enforcing a reduced power state of the redundant server, a failover system provides a desired combination of high power efficiency with low latency.
