Abstract:
An apparatus, system, and method are disclosed for data storage with progressive redundant array of independent drives (“RAID”). A storage request receiver module, a striping module, a parity-mirror module, and a parity progression module are included. The storage request receiver module receives a request to store data of a file or of an object. The striping module calculates a stripe pattern for the data. The stripe pattern includes one or more stripes, and each stripe includes a set of N data segments. The striping module writes the N data segments to N storage devices. Each data segment is written to a separate storage device within a set of storage devices assigned to the stripe. The parity-mirror module writes a set of N data segments to one or more parity-mirror storage devices within the set of storage devices. The parity progression module calculates a parity data segment on each parity-mirror device in response to a storage consolidation operation, and stores the parity data segments. The storage consolidation operation is conducted to recover storage space and/or data on a parity-minor storage device.
