Measures reported by UspDiskProcTest

A disk processor (DKP), which is contained in a disk adapter (DKA), controls data transfer between the cache and the disk devices. A disk adapter contains multiple disk processors (DKPs). If monitor data shows high DKP usage overall, you should consider installing additional HDDs and/or DKAs, and then using Volume Migration migrate the high-write-usage volumes (especially sequential writes) to the new parity groups. If the monitor data shows the imbalance usage of the DKP, you can use Volume Migration to migrate logical volumes from high-usage parity groups to low-usage parity groups.

This test is used to identify the usage of the Disk Processor.
