Title:
INPUT/OUTPUT PROCESSING SYSTEM
Document Type and Number:
Japanese Patent JP3201219
Kind Code:
B2
Abstract:
PURPOSE: To improve the throughput of the entire system by generating logical disk management data for which a stripe width for uniformizing response time required for the input/output of data for one stripe of respective disk devices is set.
CONSTITUTION: The performance characteristics of the respective disk devices for constituting the stripe are recognized by a performance measurement means 208. It is performed by using a parameter, making the disk devices execute input/output operations and measuring the response time and the result is recorded. Then, based on the measured performance data 209 of the respective disk devices, a data amount to be arranged to the respective disk devices so as to uniformize each response time required for the input/output of the data for one stripe of the disk devices for constituting a disk drive, that is the stripe width, is decided. Then, logical disk constitution data 211 according to it are constituted by a logical disk constitution means 213, that is, the logical disk device of striping constitution is constituted.
