Cleversafe Assigned Two Patents

Writing data slices to ready and non-ready distributed storage units in a distributed storage network
Cleversafe, Inc., Chicago, IL, has been assigned a patent (8,918,534), developed by Baptist Andrew, Chicago, IL, for a “writing data slices to ready and non-ready distributed storage units in a distributed storage network.”

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A distributed storage network includes a distributed storage processing unit, which generates multiple data slices from a single data segment, and multiple different storage units to store the data slices. Each data slice is assigned to a particular storage unit for storage. The distributed storage processing unit determines which of the storage units are in a ready state, and sends data slices to the ready storage units. Data slices assigned to storage units that are not in a ready state are temporarily stored in a temporary memory, e.g. cache memory, until the storage unit becomes ready. If the intended storage unit remains in a non-ready status for too long, the slices stored in cache memory can be sent to a substitute storage unit, or discarded and reconstructed at a later time.”

The patent application was filed on May 11, 2010 (12/777,864)

Distributed storage network for modification of a data object
Cleversafe, Inc., Chicago, IL, has been assigned a patent (8,914,707), developed by Resch Jason K., and Cilfone Bart, Chicago, IL, for a “distributed storage network for modification of a data object .”

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A distributed storage network generates a plurality of data segments from a data object and stores each of the plurality of data segments as a plurality of encoded data slices generated from an error encoding dispersal function. When the distributed storage network receives a modification request for the data object, it determines a size of the plurality of data segments of the data object from a segment size field and identifies one of the plurality of data segments requiring modification. The identified data segment is reconstructed from the plurality of encoded data slices and modified in accordance with the modification request.”
