Title:
Scalable memory storage
Document Type and Number:
Japanese Patent JP5957647
Kind Code:
B2
Abstract:
Techniques using scalable storage devices represent a plurality of host-accessible storage devices as a single logical interface, conceptually aggregating storage implemented by the devices. A primary agent of the devices accepts storage requests from the host using a host-interface protocol, processing the requests internally and/or forwarding the requests as sub-requests to secondary agents of the storage devices using a peer-to-peer protocol. The secondary agents accept and process the sub-requests, and report sub-status information for each of the sub-requests to the primary agent and/or the host. The primary agent optionally accumulates the sub-statuses into an overall status for providing to the host. Peer-to-peer communication between the agents is optionally used to communicate redundancy information during host accesses and/or failure recoveries. Various failure recovery techniques reallocate storage, reassign agents, recover data via redundancy information, or any combination thereof.
