Abstract
A system, method, and computer program product for the banded allocation of storage device address ranges in distributed parity schemes is disclosed. A storage system with storage devices logically divides up the storage devices into bands of contiguous logical block address ranges. A storage controller provisions logical volumes in the bands. Upon unavailability of a storage device, the data pieces are reconstructed at the next available data extent within the same band on the other storage devices. The storage controller detects a replacement drive and logically divides the replacement storage device into the same number of bands as on the other storage devices. The storage controller transfers the reconstructed data pieces to the replacement drive and places the data pieces within the same bands on the replacement drive.
