Transparent recovery of damaged or unavailable objects in replicated object storage system

Hitachi Data Systems Corp., Santa Clara, CA, has been assigned a patent (8,621,270) developed by four co-inventors for a system and method “for transparent recovery of damaged or unavailable objects in a replicated object storage system.”

The co-inventors are Benjamin Isherwood, Tewksbury, MA, Donald P. Pannese, Westford, MA, Richard Rogers, Stoughton, MA, and Vitaly Zolutusky, Arlington, MA.

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A redundant array of independent nodes are networked together. Each node executes an instance of an application that provides object-based storage. The nodes are grouped into a plurality of systems each having multiple nodes. An object recovery method comprises: receiving, by a first system of the plurality of systems from a client application, a read request for an object, the object having been replicated to/from at least one second system among the plurality of systems; if the object of the read request is available in the first system, returning by the first system the object of the read request to the client application; and if the object of the read request is not available in the first system, performing a read from replica process by the first system to access a replica of the object from a second system among the plurality of systems and using the replica of the object to return the object of the read request to the client application.”

The patent application was filed on Sept. 24, 2010 (12/889,641).
