STORAGE MANAGEMENT SYSTEM FOR PRESERVING CONSISTENCY OF REMOTE COPY DATA |
摘要 |
A storage control system adapted to operate as a remote copy pair by communicating between a primary and a secondary of the remote copy pair comprises a selector for selecting writes to be placed in a batch based on one or more criteria, a sequence number requester for requesting a sequence number for the batch, and a sequence number granter for granting a sequence number for the batch. The storage control system also comprises a batch transmitter for transmitting the batch to the secondary, a permission receiver for receiving a permission to write the batch from the secondary, and a write component responsive to the permission receiver to write the batch to completion, wherein the secondary is responsive to the completion to grant a further permission to write for a further batch. |
