Dell Assigned Patent

Dell Products LP, Round Rock, TX, has been assigned a patent (8,849,774) developed by four co-inventors for “heat indices for file systems and block storage.”

The co-inventors are Abhijit Dinkar, San Jose, CA, Vinod Jayaraman, San Francisco, Murali Bashyam, Fremont, CA, and Goutham Rao, Los Altos, CA.

The abstract of the patent published by the U.S. Patent and Trademark Office states: “Techniques and mechanisms are provided to allow for selective optimization, including deduplication and/or compression, of portions of files and data blocks. Data access is monitored to generate a heat index for identifying sections of files and volumes that are frequently and infrequently accessed. These frequently used portions may be left non-optimized to reduce or eliminate optimization I/O overhead. Infrequently accessed portions can be more aggressively optimized.”

The patent application was filed on Dec. 5, 2013 (14/098,156).
