摘要： PROBLEM TO BE SOLVED: To enable to access simultaneously from a plurality of physical paths to a same volume so as not to allow reserve release from a path except for the path in a path group.
SOLUTION: (a) Path information as the path group is input from a personal computer PC, and the path group is managed on a side of a storage control device SCS. (c) Persistent Reserve OUT is specified on a path PS#1 by a host HOST A. The storage control device SCS recognizes the reserve from the entire path group PG#1 including the path PS#1. (d) A Persistent Reserve OUT (Release specification) command is issued in a KEY #1 so as to release a reserving status of the path PS#1 of the host HOST A improperly from a host HOST B. (e) However, because the path PS#1 does not belong to the path group managed by the storage control device SCS, a reserve release request is rejected.

摘要： PROBLEM TO BE SOLVED: To switch operation to attach importance to throughput performance and operation to attach importance to response time according to distance to a host device. SOLUTION: In this storage controller 10, information regarding the distance to the host devices A20, B30, C40 is inputted from a service processor 50, the information is held in a connection distance information table 1060 and a degree of multiplexing of I/O to be processed on the side of the storage controller is controlled by every host device by referring to the connection distance information table 1060. Thus, the throughput performance is enhanced by increasing the number of I/O to which a multiple I/O processing is performed when the distance to the host devices is large and the response time is shortened by reducing the number of I/O to which the multiple I/O processing is performed or performing a single I/O processing when the distance to the host devices are small.

摘要： PROBLEM TO BE SOLVED: To prevent a device having the function of command queuing from receiving a lot of commands. SOLUTION: The number of commands, for which issue is completed but the end is not reported, to the device having the function of command queuing is counted. When issuing a new command, the said number of commands is compared with the number of inflow limits. If the said number of commands is less than the number of inflow limits, the said new command is issued, but if the said number of commands is not less than the said number of inflow limits, the said new command is not issued (step 526). Thus, concerning the device having the function of command queuing, occurrence of overhead to return a lot of busy is prevented. Therefore, this device can be concentrated in original processing to commands so that processing efficiency is improved.
