Evacuating blades in a storage array that includes a plurality of blades

Abstract:

Evacuating blades in a storage array that includes a plurality of blades, including: detecting an occurrence of a blade evacuation event associated with one or more blades; iteratively until migration has completed for each of the blades associated with the blade evacuation event: selecting, in dependence upon a blade redundancy policy, one or more next blades to be evacuated from the storage array; migrating, from the one or more next blades to one or more blades in the storage array that are not associated with the blade evacuation event, data stored on the next blade; and migrating, from the one or more next blades to one or more blades in the storage array that are not associated with the blade evacuation event, storage array computational workloads executing on the one or more next blades.
