Abstract:
An apparatus, system, and method are disclosed for a shared, front-end, distributed redundant array of independent drives (“RAID”). A multiple storage request receiver module receives at least two storage requests from at least two clients to store file or object data in one or more storage devices of a storage device set. The storage requests are concurrent and have at least a portion of the data in common. The storage device set includes autonomous storage devices forming a RAID group. Each storage device is capable of independently receiving storage requests from a client over a network. A striping module calculates a stripe pattern and writes N data segments per stripe to N storage devices. A parity-mirror module writes a set of N data segments to parity-mirror storage devices. A sequencer module ensures completion of a first storage request prior to executing a second storage request.
