Patent number: 10783131Abstract: A system and method for efficiently storing data in a storage system. A data storage subsystem includes multiple data storage locations on multiple storage devices in addition to at least one mapping table. A data storage controller determines whether data to store in the storage subsystem has one or more patterns of data intermingled with non-pattern data within an allocated block. Rather than store the one or more pattern on the storage devices, the controller stores information in a header on the storage devices. The information includes at least an offset for the first instance of a pattern, a pattern length, and an identification of the pattern. The data may be reconstructed for a corresponding read request from the information stored in the header.Type: GrantFiled: January 3, 2018Date of Patent: September 22, 2020Assignee: Pure Storage, Inc.Inventors: Marco Sanvido, Richard Hankins, John Hayes, Steve Hodgson, Feng Wang, Sergey Zhuravlev, Andrew Kleinerman
