Abstract: The storage system includes first and second disk arrays. The first disk array has a first port coupled to a second port of the second disk array, a port controller controlling the first port, a plurality of disk devices to store data, and a controller managing a plurality of logical units on the plurality of disk drives. The first port controller controls the first port so as to execute, in a time-sharing manner, data transfer corresponding to a initiator task and data transfer corresponding to a target task. The initiator task is generated to execute the data transfer from a first logical unit on the plurality of disk drives of the first disk array to a second logical unit on a plurality of disk drives of the second disk array. The target task is generated to execute the data transfer to receive data from the second disk array.

Abstract: A disk array connected to a storage area network via a fiber channel has one or more ports each controlled by a processor. Even the disk array with one port and one processor executes online processing and backup processing at the same time while considering an online processing load. A port controller not only accepts a request from a host computer but issues a request to other storage controllers to allow online processing and backup processing to be executed at the same time. In addition, the disk array, if provided with a plurality of ports, selects ports or schedules processing depending upon the load to prevent backup processing from affecting online processing performance.

Abstract: A storage sub-system employs a staging control information table by which staging of data to be read and redundant data thereof can be executed together to reduce response time in the event of a data read failure. The staging control information table also permits pre-read staging to be executed in the forward, backward or both the forward and backward directions, to reduce response time.
