    摘要： A method for data distribution, including distributing logical addresses among an initial set of devices so as provide balanced access, and transferring the data to the devices in accordance with the logical addresses. If a device is added to the initial set, forming an extended set, the logical addresses are redistributed among the extended set so as to cause some logical addresses to be transferred from the devices in the initial set to the additional device. There is substantially no transfer of the logical addresses among the initial set. If a surplus device is removed from the initial set, forming a depleted set, the logical addresses of the surplus device are redistributed among the depleted set. There is substantially no transfer of the logical addresses among the depleted set. In both cases the balanced access is maintained.

    摘要： A method for continuous data protection in a storage system, including receiving a first write command to write first data to a partition of a logical volume and then generating a first partition descriptor record (PDR) having a first timestamp. The method further includes storing the first data at a first location, associating the first PDR with the first location, and receiving a second write command, subsequent to the first command, to update the first data with second data. Responsively to the second command, a second PDR having a second timestamp is generated. The second data is stored at a second location, and the second PDR is associated with the second location. The method includes generating a pointer between the first PDR and the second PDR, and accessing the first PDR using the pointer in response to a read command indicating a time prior to the second timestamp.

    摘要： A method for managing multiple logical volumes in a data storage system, including providing physical storage of a given capacity within the data storage system, and adding a logical volume of a given size within the data storage system so as to cause a total amount of logical storage of the logical volumes in the data storage system to be greater than the given capacity of the physical storage. The method includes verifying, in response to a write command to store data in the logical volume, that a physical storage location is available in the physical storage and, if the physical storage location is available, then storing the data at the physical storage location.

    摘要： A system and method are described to improve the efficiency of copy-on-write operations in a storage system. A PDSS descriptor associated with partition PSS and a PDTT descriptor associated with partition PTT are maintained in a cache memory, with partition PSS associated with a source logical unit LUS and partition PTT associated with a source logical unit LUT. An ICP flag is set in the PDSS and PDTT descriptors indicating that the PSS and PTT are undergoing a copy-on-write operation. Data is then dissociated with PTT and locations of each block of the PSS stored in memory are copied from the PDSS descriptor to the PDTT descriptor. A task is then created to fetch blocks of the PSS and the fetched blocks are copied from the PSS to the PTT.
