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.

摘要： This invention relates to an asynchronous remote copying (ARC) system adapted to operate as a remote copy pair by communicating between primary storage and remote storage of a remote copy pair. The system comprises a primary controller for receiving a write command and writing data to primary storage; a remote controller for receiving a write command and writing data to remote storage; an ARC controller for suppressing the release of the write command to the remote controller if a delay between receiving the write command and the time when the remote storage may accept the data is more than a threshold delay, and the primary controller suppresses recording the data in primary storage until release of the write command to the remote storage.

摘要： An apparatus achieves data communications between a data storage controller and data storage devices within a data storage system via an optical network. The apparatus includes a wavelength division multiplexing logic for simultaneously establishing, on the optical network, a number of arbitrated communications loops between the controller and the data storage system, for communicating data between the controller and the storage devices.
