Abstract: Methods, computer systems, and computer readable medium are described for low latency reads using cached deduplicated data, including: receiving a request to read data from a storage system; query, using a generated hash value associated with the request to read data, one or more deduplication tables that corresponds to the hash value; and responsive to determining that the one or more deduplication tables includes an entry that corresponds to the hash value, using a mapping contained in the entry to perform the requested to read data, wherein the mapping includes a pointer to a physical location where at least a portion of the data is stored.

Abstract: A system and method comprising: receiving a request to write data stored at a first range of a first volume to a second range of a second volume, where first metadata for the first range of the first volume is associated with a range of physical addresses where the data is stored in the storage system; and responsive to receiving the request: creating second metadata for the second range of the second volume, wherein the second metadata is associated with the range of physical addresses where the data is stored in the storage system; and associating the second volume with the second metadata.

Abstract: Providing authorization and authentication in a cloud for a user of a storage array includes: receiving, by a storage array access module from a client-side array services module, a token representing authentication of user credentials and authorized access privileges defining one or more storage array services accessible by the user, where the token is generated by a cloud-based security module upon authentication of the user credentials and identification of authorized access privileges for the user; receiving, by the storage array access module from the user, a user access request to one or more storage array services; and determining, by the storage array access module, whether to grant the user access request in dependence upon the authorized access privileges represented by the token.

Abstract: Prioritizing garbage collection based on the extent to which data is deduplicated, including: determining, for one or more data elements, a number of deduplicated references to each data element; storing, for each of the data elements, the data element in an area of the storage device that contains other data elements with a similar number of deduplicated references; and adjusting a garbage collection schedule for the storage device, wherein garbage collection operations are performed more frequently on areas of the storage device that contain data elements with a relatively low number of deduplicated references.
