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; a sequence number granter for granting a sequence number for the batch; 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.
