Abstract
In a network computing environment, in which data stored at a primary storage system, is mirrored from the primary storage system to a secondary storage system, a selection may be made to direct an input/output operation such as a read operation, for example, to the secondary storage system instead of the primary storage system in order to improve operations. For example, a read operation may be directed to the secondary storage to improve the read operation response time. In other aspects, a read or other input/output operation may be directed to the secondary storage to improve utilization of the resources of the secondary storage system. Other aspects are described.
