摘要： A system and method for data storage in an array. A system includes a client coupled to a storage subsystem including data storage locations addressable as rows and columns in an array. Each column comprises a separate storage device. Each row includes redundant data. For a given row, a coordinating storage device coordinates the computation and storage of redundant data. The system detects a failure of a storage region and in response, configures an overlay storage device to temporarily overlay the failed region, maintains an association between the overlay device and the failed region, and maintains a record of changes made to the overlay device while the region is in a failed state. In response to detecting that the failed region has been restored, the system uses the association to identify the overlay device and uses the record of changes made to the overlay device to resynchronize the failed region.

摘要： A method involves generating a block-level write operation, which causes a value to be written to a primary volume, and generating information indicative of whether any of the block-level write operation should be transferred to a secondary site during replication of data in the primary volume. The information can indicate that all, part, or none of the block-level write operation should be transferred to the secondary site. If the information indicates that less than all of the block-level write operation should be transferred to a secondary site, the information can also indicate that logical information associated with the block-level write operation should be transferred to the secondary site instead of transferring the value being written by the block-level write operation.
