Abstract: A storage system is described. The storage system may include a plurality of storage tiers, each including at least one storage device, each storage device including storage and a controller. Metadata storage may store metadata for an image stored in the plurality of storage tiers, which includes a location in the plurality of storage tiers where the image is stored. A receiver may receive a request to access the image from a host. Retrieval software, executed by a processor, may retrieve the image from the plurality of storage tiers using the location where the image is stored. A transmitter may transmit the image to the host.

Abstract: A system and method for using a Solid State Drive (SSD) (505) are described. Reception circuitry (510) may receive write requests (1610, 1615, 1620, 1625) and invalidate requests (1630, 1635, 1640) from a first stream (305, 320, 335, 350). The write requests (1610, 1615, 1620, 1625) may request that data be written to storage (520) on the SSD (505); invalidate requests (1630, 1635, 1640) may invalidate data written to the storage (520). A statistics calculation logic (1705) may calculate statistics (1410, 1415, 1510) for the stream based on the write requests (1610, 1615, 1620, 1625) and the invalidate requests (1630, 1635, 1640). A performance logic (1710) may use the calculated statistics (1410, 1415, 1510) to improve the performance of the SSD (505).
