Abstract:
A method to optimize workload across a plurality of storage devices of a storage system, where the method monitors a workload of a first storage device belonging to a first tier of the storage system, calculates a performance of the workload of the first storage device belonging to a first tier of the storage system, interpolates a performance threshold for the first storage device using the workload pattern of the first storage device and a profile of the first storage device, the profile identifying a benchmark performance of the first storage device, and optimizes a usage of the first storage device within the storage system to improve a performance of the first storage device.
