The abstract of the patent published by the U.S. Patent and Trademark Office states: “Described are techniques for performing data storage system management. The data storage system is divided into a plurality of virtual partitions. A plurality of policy sets are specified where each of the policy sets includes one or more policies. One of the plurality of policy sets is assigned to each of the plurality of virtual partitions. Each of the plurality of policy sets includes an access control policy that assigns a portion of data storage of the data storage system as a resource for exclusive use in one of the plurality of virtual partitions that is assigned said each policy set.“

The patent application was filed on November 26, 2013 (14/089,931 ).

Managing storage operations in server cache
EMC Corporation, Hopkinton, MA, has been assigned a patent (8,904,061) developed by O’Brien, III, Walter A. Westborough, MA, Linnell, Thomas E., Northborough, MA, Clark, Roy E., Hopkinton, MA and Harwood, John S., Paxton, MA, for a “managing storage operations in a server cache”.

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A method is used in managing storage operations in a data storage environment. An I/O request is received a server having a server cache where the server cache contains cached data previously supplied from a storage system in communication with the server. At the storage system, determine if the I/O request can be at least partially satisfied from the cached data.“

The patent application was filed on December 30, 2011 (13/341,193).

Cloud capable storage system
with high performance nosql key-value pair operating environment
EMC Corporation, Hopkinton, MA, has been assigned a patent (8,904,047) developped by Kornfeld, Sergey, Waltham, MA, Hushon, Jr., John D., Medfield, MA, Knopov, Lev, Brookline, MA, Achkinazi, Igor, Northborough, MA, Torres, Luis O., Shrewsbury, MA, Sahin, Adnan, Needham, MA, Kirac, Ahmet, Guttenberg, NJ and Duerk, Bryan, Shrewsbury, MA, for a “cloud capable storage system with high perormance nosql key-value pair operating environment .“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “Described are techniques for processing data operations. A request is sent from an application to perform a data operation on a key-value data store. The request is in accordance with a first application-level protocol for performing the data operation on the key-value data store and includes a first key of a first key-value pair used by a data storage system to perform the data operation. The request is received at the data storage system such as by a key-value server that processes requests in accordance with the first application-level protocol for the key-value data store. In response to receiving the request at the data storage system, first processing is performed on the data storage system for the data operation and a response is returned to the application.“

The patent application was filed on June 29, 2012 (13/538,360).
