Cleversafe Assigned Two Patents

Establishing trust in maintenance free storage container
Cleversafe, Inc., Chicago, IL, has been assigned a patent (8,954,787) developed by Gladwin, S. Christopher, Resch, Jason K., Chicago, IL, Grube, Gary W., Barrington Hills, IL, and Markison, Timothy W., Mesa, AZ, for a “establishing trust in a maintenance free storage container.”

The abstract of the patent published by the U.S. Patent and Trademark Office states: ”A maintenance free storage container includes a plurality of storage servers, wherein the maintenance free storage container allows for multiple storage servers of the plurality of storage servers to be in a failure mode without replacement. The maintenance free storage container further includes a container controller operable to manage failure mode information of the plurality of storage servers, manage mapping of a plurality of virtual storage servers to at least some of the plurality of storage servers based on the failure mode information, communicate storage server access requests with a device external to the maintenance free storage container using addressing of the plurality of virtual storage servers, and communicate the storage server access requests within the maintenance free storage container using addressing of the plurality of storage servers.“

The patent application was filed on April 18, 2012 (13/450,212).

Data migration in dispersed storage network
Cleversafe, Inc., Chicago, IL, has been assigned a patent (8,954,667) developed by Dhuse, Greg, Baptist, Andrew, Chicago, IL, Leggette, Wesley, Oak Park, IL, Volvovski, Ilya, Chicago, IL, and Resch, Jason K., Chicago, IL, for a “data migration in a dispersed storage network.”

The abstract of the patent published by the U.S. Patent and Trademark Office states: ”A method begins by processing module determining data to migrate, wherein the data is stored as a plurality of sets of encoded data slices in a first set of dispersed storage, DS) units. The method continues with the processing module retrieving at least a read threshold number of encoded data slices for each set of the plurality of sets of encoded data slices and dispersed storage error decoding the at least the read threshold number of encoded data slices in accordance with error coding dispersal storage function parameters to reproduce the data. The method continues with the processing module dispersed storage error encoding the data in accordance with second error coding dispersal storage function parameters to produce a plurality of sets of second encoded data slices and sending at least a write threshold number of second encoded data slices to a second set of DS units for storage therein.“

The patent application was filed on November 10, 2010 (12/943,826).
