    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: 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: Mechanisms are provided for extending cache for an external storage system into individual servers. Certain servers may have cards with cache in the form of dynamic random access memory (DRAM) and non-volatile storage, such as flash memory or solid-state drives (SSDs), which may be viewed as actual extensions of the external storage system. In this way, the storage system is distributed across the storage area network (SAN) into various servers. Several new semantics are used in communication between the cards and the storage system to keep the read caches coherent.
