Formation Data Systems Assigned Patent
Dynamic storage tiering based on performance SLAs
By Francis Pelletier | November 28, 2016 at 2:42 pmFormation Data Systems, Inc., Fremont, CA, has been assigned a patent (9,489,137) developed by Lewis, Mark S., Pleasanton, CA, Rao, Vinay P., and Povzner, Anna, San Jose, CA, for a “dynamic storage tiering based on performance SLAs.“
The abstract of the patent published by the U.S. Patent and Trademark Office states: “Data objects are stored on storage devices, taking into account service level agreements or other quality of service parameters. In one aspect, data objects grouped into storage volumes. In addition, the storage devices are classified into different level storage tiers, where higher level storage tiers have higher performance and lower level storage tiers have lower performance. Ranks for the data objects are calculated, based on both a data usage pattern for the data object, (e.g., recency and frequency) and on quality of service, (QOS) parameters for the storage volume containing the data object. Examples of QOS parameters include service level agreements, priority, minimum and maximum input/output operations per second. The data objects are then stored on storage devices, based on the data objects’ ranks and the storage devices’ storage tiers.“
The patent application was filed on February 5, 2015 (14/614,779).
