Abstract
A simulation tool provides candidate volume mirror simulation in a data storage system. In one embodiment, user selections are received including a user selection of one or more candidate volumes of a primary data storage system for simulating mirroring to a secondary data storage system. As a function of received user selections, host-to-primary I/O activity to a candidate volume is simulated, recorded and measured over a selected interval of time. In addition, primary-to-secondary mirroring of a selected candidate volume to the secondary data storage system is simulated, recorded and measured over the interval of time. Performance measurements of the candidate volume mirror simulation are output by the simulation tool. Other features and aspects may be realized, depending upon the particular application.
