    摘要： A storage area network (SAN) controller and method for storing and replicating data between sites in a storage area network in which storage controllers at each site implement storage virtualization. A storage cell is implemented at each site comprising at least one storage controller and a pool of physical storage coupled to the controller. A copy set comprising a logical unit (LUN) of storage, referred to as a member, in each of the storage cells is defined. As operational data transactions are performed against one of the members of a copy set, they are replicated, immediately or after a delay, in each other member of the copy set. As changes are made to dependent attributes such as size of one member of the copy set, the change is replicated in each other member of the copy set automatically. Changes can be made in the independent attributes such as size of each member of the copy set independently of other members of the copy set.

    摘要： A data storage system adapted to maintain redundant data storage sets at a destination location(s) is disclosed. The data storage system establishes a copy set comprising a source volume and a destination volume. Data written to a source volume is automatically copied to the destination volume. The data storage system maintains a data log that may be activated when the destination volume is inaccessible due to, for example, a malfunction in the destination storage system or in the communication link between the source system and the destination system. I/O commands and the data associated with those commands are written to the data log, and after a destination system becomes available the information in the data log is merged into the destination volume to conform the data in the destination volume to the data in the source volume. The data log competes for disk capacity with other volumes on the system, and log memory is allocated as needed. During the merge process the system maintains the ratio of merge data writes out of the data log to data writes from a host computer into the data log within a desired range until the data log reaches a predetermined size, whereupon data writes into the data log are quiesced to permit the merge write process to complete.

The data storage system establishes a copy set comprising a source volume and a destination volume. Data written to a source volume is automatically copied to the destination volume. The data storage system maintains a data log that may be activated when the destination volume is inaccessible due to, for example, a malfunction in the destination storage system or in the communication link between the source system and the destination system. I/O commands and the data associated with those commands are written to the data log, and after a destination system becomes available the information in the data log is merged into the destination volume to conform the data in the destination volume to the data in the source volume. The data log competes for disk capacity with other volumes on the system, and log memory is allocated as needed. In operation, the array controllers monitor connection status between array controllers in a DRM group. When a connection failure is detected the controllers determine which of the remaining controllers determine whether the source controller remains online, and if not then which destination controller should assume the role of the source controller.

    摘要： A storage system permits virtual storage of user data by implementing a logical disk mapping structure that provides access to user data stored on physical storage media and methods for generating point-in-time copies, or snapshots, of logical disks. A snapshot logical disk is referred to as a predecessor logical disk and the original logical disk is referred to as a successor logical disk. Creating a snapshot involves creating predecessor logical disk mapping data structures and populating the data structures with metadata that maps the predecessor logical disk to the user data stored on physical media. Logical disks include metadata that indicates whether user information is shared between logical disks. Multiple generations of snapshots may be created, and user data may be shared between these generations. Methods are disclosed for maintaining data accuracy when write I/O operations are directed to a logical disk.

    摘要： Metadata architecture and associated methodology for a data storage system employing a grid-based storage capacity wherein each grid defines a storage unit in terms of a plurality of storage domains along one axis against one or more rows of a plurality of storage stripes along another axis, and wherein a grid grouping of two or more grids defines a sheet of data storage capacity. The metadata comprises identification information stored in a memory space characterizing an allocation status of the sheets in the storage capacity. A method is provided for allocating memory for the grid-based storage capacity comprising determining whether the allocation is associated with an existing logical device. If the determining step is associated with an existing logical device, then a logical device allocation map and a sheet allocation table are accessed to allocate a selected storage unit. Otherwise, a sheet allocation descriptor and a sheet allocation map are accessed to allocate a selected storage unit. A method is provided for transferring data for the grid-based storage capacity comprising accessing a logical device allocation map and a drive organization table to transfer data to or from a selected storage unit.
