Abstract
Provided are a computer program product, system, and method for modeling workload information for a primary storage and a secondary storage. A determination is made of: a first type and second type of Input/Output (I/O) operations with respect to extents configured in the primary storage; a cumulative I/O workload for the primary storage based on a first type and a second type of I/O operations at different cumulative storage amounts of the primary storage indicating a concentration of the I/O workload on the primary storage; and cumulative I/O workload for the secondary storage based on the first type and the second type of I/O operations at different storage amounts indicating a concentration of the I/O workload of the first type of I/O operations on the secondary storage. A performance gap is determined based on the cumulative I/O workloads for the primary and secondary storages at one of the storage amounts.
