Abstract: Methods and apparatus for a system including a storage array with solid state drive (SSD) storage and a controller coupled to the SSD storage. The controller may include a data system to perform input/output operations to the SSD storage, a control system coupled to the data system to control an address to hash value mapping, a routing system coupled to the control system to process commands from remote hosts, segment data into data blocks, and generate the hash values for the data blocks, and a data server associated with the routing system to receive read and write commands from a data client running on a remote host, wherein the storage array contributes a portion of the SSD storage to storage pools of a distributed elastic storage system.

Abstract: Example embodiments of the present invention relate a method, a system, and a computer program product for extent-based tiering for virtual storage using full LUNs. The method includes exposing a virtual LUN comprising a first LUN in a first tier of storage having a first latency and a second LUN in a second tier of storage having a second latency and managing the virtual LUN according to properties of the first LUN, properties of the second LUN, and a policy.
