摘要： Mechanisms for managing data segments in a tiered storage system are provided. The mechanisms maintain at least one counter for each data segment in the tiered storage system. Each counter in the at least one counter counts a number of access operations to a corresponding data segment for a predetermined time interval. The mechanisms further perform one or more analytical operations based on one or more values of the at least one counter for each data segment to make residence determinations for each data segment. The mechanisms also adjust a storage location of one or more data segments in tiers of the tiered storage system to thereby move the one or more data segments to appropriate tiers of the tiered storage system based on results of the one or more analytical operations.

摘要： A mechanism is provided in a storage device for performing a write operation. The mechanism configures a write buffer memory with a plurality of write buffer portions. Each write buffer portion is dedicated to a predetermined block size category within a plurality of block size categories. For each write operation from an initiator, the mechanism determines a block size category of the write operation. The mechanism performs each write operation by writing to a write buffer portion within the plurality of write buffer portions corresponding to the block size category of the write operation.

摘要： An apparatus, system, and method are disclosed for enhanced block-level deduplication. A computer program product stores one or more express block signatures in an express directory that meet a reference count requirement. The computer program product also stores one or more primary block signatures and one or more reference counts for the primary block signatures in a primary directory. Each primary block signature has a corresponding reference count. The computer program product determines whether a block signature for a data block matches one of the one or more express block signatures stored in the express directory.

摘要： A controller receives a request to perform staging or destaging operations with respect to an area of a cache. A determination is made as to whether one or more discard scans are being performed or queued for the area of the cache. In response to determining that one or more discard scans are being performed or queued for the area of the cache, the controller avoids satisfying the request to perform the staging or the destaging operations with respect to the area of the cache.

摘要： Modified tracks for write requests to a sequential access storage medium in a sequential access storage device are cached in a non-volatile storage, which is a faster access device than the sequential access storage medium. A request queue includes destage requests to destage the modified tracks in the non-volatile storage device to the sequential access storage medium and read requests to access read requested tracks from the sequential access storage medium. A comparison is made of a current position of a read/write mechanism with respect to physical locations on the sequential access storage medium of the tracks subject to the destage requests indicated in the request queue. A determination is made of one of the destage requests to process based on the comparison. The modified track for the determined destage request is written from the non-volatile storage device to the sequential access storage medium.
