Abstract

A periodic rotational vibration check for storage devices to compensate for varying loads is disclosed. A variable representing rotational vibration status is maintained in a rotational vibration log. The variable is processed to determine whether a storage device exhibits a rotational vibration issue. Workload analysis is performed to identify a change to the workloads run on physically separate hardware to resolve the rotational vibration issue and thus eliminate the need for more expensive hardware.
