Abstract:
A storage system in a remote copy configuration includes a redirect mechanism. The redirect mechanism determines whether to redirect read operations to a remote storage system, which is part of the remote copy configuration, based on a power management policy and a redirect policy. The redirect mechanism takes into account response time data, input/output demand, power utilization data, and input/output classes and priorities to determine whether to redirect read access requests to the remote storage system. Redirection of read operations to the remote storage system results in reduced power consumption at the local system.
