摘要： Methods and apparatus for migrating a logical object. In one embodiment, a migration is performed by automatically determining the source location(s) of the logical object, moving the data stored therein to a target location while maintaining the availability of the data at the source location to an application program, and automatically servicing access requests from the application program at the target location after moving the data. In another embodiment, a migration is performed by automatically provisioning target location(s) to store a logical object, moving the data in the logical object to the target location(s) while maintaining its availability to an application program, and automatically servicing access requests from the application program at the target location after moving the data. In a further embodiment, a migration is performed by moving the data within a logical object from a source logical volume to a target logical volume, automatically servicing access requests from an application program at the target logical volume after moving the data, and retiring the source logical volume.

摘要： Method and apparatus for restoring copies of a logical object to a primary computer storage device are disclosed. A copy of the logical object is provided, physical blocks of memory in the primary storage device are allocated, a map of the data blocks will be copied to the physical blocks of the primary storage devices created. The copying may then occur using the created map. The copy of the logical object may be an abstract bloc set, which includes data blocks of the logical object potentially out of order and metadata identifying relative position of the data blocks.

摘要： Methods and apparatus for performing a data migration in a clustered computer system. In one aspect, the availability of the data being migrated is maintained during the migration. In another aspect, a data set is migrated by a transfer utility in one of the hosts in the cluster, and in response to a failure of the host, the migration is resumed without restarting from the beginning point of the data set. In a further embodiment, the hosts in the cluster have agents associated therewith to manage the data migration, and prior to taking at least one action associated with the data migration, the agents coordinate to ensure that the hosts in the cluster are prepared to have the at least one action taken.

摘要： One embodiment of the invention relates to a storage system processing a request received from a host computer for content units that meet at least one selection criterion specified in the request. The storage system may identify content units stored thereon that meet the selection criterion or criteria and return these content units to the host computer in response to the request. In another embodiment, while the storage system is in the process of identifying and returning content units in response to the request, a second host computer may send an instruction to the storage system requesting to receive a portion of the content units that satisfy the search criterion or criteria. In response, the storage system may begin providing a portion of the content units that satisfy the selection criterion or criteria and that have not already been provided to the host computer that sent the request to the second host computer.
