APPARATUS, SYSTEM, AND METHOD FOR A SHARED, FRONT-END, DISTRIBUTED RAID

摘要

Disclosed is a shared, front-end, distributed RAID. A multiple storage request receiver module (2302) receives at least two storage requests from at least two clients (114) to store file or object data in one or more storage devices (150) of a storage device set (1604). The storage requests are concurrent and have at least a portion of the data in common. The storage device set (1604) includes autonomous storage devices (150) forming a RAID group. Each storage device (150) is capable of independently receiving storage requests from a client (114) over a network (116). A striping module (2304) calculates a stripe pattern and writes N data segments per stripe to N storage devices (150). A parity-mirror module (2306) writes a set of N data segments to parity-mirror storage devices (1602). A sequencer module (2308) ensures completion of a first storage request prior to executing a second storage request.
