Abstract
Monitoring the division of input/output (I/O) loading within a storage system is provided where the storage system includes one or more storage devices and one or more ranks, each rank including a plurality of extents. The I/O loading of individual extents is estimated for each of the one or more ranks of the storage system by determining an average disk utilization in a rank, measuring a total heat for all extents in the rank, and based on the determined average disk utilization in the rank and the measured total heat for all extents in the rank, calculating a contribution of each extent to the utilization of the rank.
