Abstract

See full text

A mirrored storage system comprising a system controller coupled to a first storage system comprising a primary controller and a first storage and to a second storage system comprising a secondary controller and a second storage. The second storage contains an image of data stored in the first storage. The system controller receives data to be written to storage and sends the data to the primary controller of the first storage system and to the secondary controller of the second storage system. The system controller instructs the primary controller to write the data to the first storage of the first storage system in an ordered manner; and instructs the secondary controller to write the data sequentially to a data area on the second storage of the second storage system. Writing the data sequentially to the second storage improves the write performance.
