Abstract
Techniques are described for determining I/O workload. A first device of a first data storage system and a second device of a second data storage system are configured as synchronous mirrored devices of a first logical device. The host issues I/O operations to the first logical device over first and second paths. First I/O workload information is determined for a first data portion of the first logical device. Second I/O workload information is determined for the first data portion. The first I/O workload information and the second I/O workload information each include a first number of read operations that is a sum of read operations directed to the first logical device over both the first path and the second path. Data storage optimizations are performed on the first data storage system using the first I/O workload information and/or the second data storage system using the second I/O workload information.
