摘要： This specification describes a method and apparatus for storing data in a reduced redundancy form. Binary Large Objects (BLOBs) are partitioned into subblocks according to a partitioning method, and the subblocks are stored in subblock clusters. Each BLOB is represented as a list of spans of subblocks which identifies a contiguous sequence of subblocks within a cluster. Storage redundancy can be reduced because the spans of two different BLOBs can refer to the same subblocks. An index may be used to map subblock hashes to subblock cluster numbers.

摘要： The disk array device supplies appropriate power to various parts in accordance with the operating mode in cases where the output of the main power supply drops. The disk array device adjusts the power from a commercial power source 6 with an AC/DC power supply 5, and supplies this power to a power supply common bus 7. A disk drive group 1 and a control circuit board group 2 constituting electrical loads are respectively connected to the power supply common bus 7. When the supply of power from the main power supply stops, the capacitor box 3 supplies a relatively large current for a short time only, in order to retain data during an instantaneous power outage. Then, the battery boxes 4 supply power to the power supply common bus 7 for a relatively long period of time, in order to perform destage control and memory backup. The battery boxes 4 perform balancing control of the output current in order to suppress variation in the output current value among the battery boxes 4.

摘要： A hierarchic disk array data storage system (10) has multiple storage disks (12) that define a physical storage space (34) and a RAID management system (16) that maps the physical storage space (34) into two virtual storage spaces. A RAID-level virtual storage space (40) presents the physical storage space as mirror and parity RAID areas where the mirror RAID areas store data according to RAID Level 1 and the parity RAID areas store data according to RAID Level 5. An application-level virtual storage space (50) presents the physical storage space as multiple virtual blocks. The RAID management system (16) migrates data between the mirror and parity RAID areas to optimize performance and reliability. To facilitate migration, the RAID management system (16) guarantees a minimum of unused storage space that can be used to empty a RAID area for the purpose of converting the RAID level or other storage attribute of the RAID area. The minimum unused storage space is preferably equivalent in size to at least one largest parity RAID area. However, the unused storage space is not in any one physical location, but can be allowed to distribute itself over various RAID areas in a non-contiguous manner across the storage disks.

摘要： A storage switch (304) in accordance with an embodiment of the invention is a highly scalable switch that allows the creation of a SAN that is easy to deploy and that can be centrally managed. Moreover, such a storage switch also allows the deployment of a global infrastructure, allowing the resources of the SAN, such as storage devices (306), to essentially be positioned anywhere on the globe. To further enable wire-speed processing, a switch in accordance with the invention has “intelligence” distributed to each of its linecards, through which it classifies packets into data and control packets, and performs virtualization functions. A switch in accordance with the invention further performs serverless storage services such as mirroring, snapshot, and replication.

摘要： An information storage controller comprises two memory groups. When one memory group is used for external communication, while the other memory group communicates with a plurality of magnetic disks, so that works in each memory group is performed in parallel. Information is transmitted between the external and the magnetic disk by changing an object to be worked by a switch means. Further, the information storage controller comprises a redundant information generation circuit for reading information in a plurality of memories with an exclusive circuit simultaneously to generate redundant information and to verify and recover data. Thus, a high speed information storage controller connected to a plurality of magnetic disks can be provided.

摘要： A computer system comprises a host processor, host memory, and a mass storage device interconnected via a high-speed data bus. An operating system and a driver for the mass storage device are implemented on the host processor. The mass storage device is capable of being connected to the computer system via the data bus, such that a portion of the host memory is allocated for use by the mass storage device; the mass storage device uses the host memory portion for one or more particular mass storage device operations; and the operating system and the driver are unaware of how the mass storage device uses the host memory portion. In a preferred embodiment, the mass storage device requests and the host processor allocates a portion of host memory for exclusive use by the mass storage device to perform such functions as predictive failure analysis, maintenance of deallocated sector lists, and data prefetching.
