Apparatus for forming logical disk management data having disk data stripe width set in order to equalize response time based on performance

摘要

A high-speed large quantity data transfer system is realized using a synchronous control means having striped disks in which a synchronizing cost between disks is reduced by software control, using time-out means, and using a data transfer means where user memory is not used. An input-output processing system for inputting and outputting a large quantity of data comprising a logical disk control means, the logical disk control means comprises a performance data collection means for collecting data, a logical disk construction means for constructing a logical disk apparatus using said plurality of disk apparatus, where said logical disk construction means forms logical disk management data so that the stripe width is set in order to equalize response time needed for input and output corresponding to one stripe data of each disk apparatus constructing said logical disk apparatus; and said logical disk control means controls said logical disk apparatus by said logical disk management data.
