<p><P>PROBLEM TO BE SOLVED: To attain a reduced I/O latency while maintaining a reduced physical capacity of a storage. <P>SOLUTION: A method of controlling a storage system includes: storing data in a first volume in the storage system which has volumes including the first volume and a plurality of second volumes; prohibiting write I/O (input/output) access against the first volume after storing the data in the first volume; performing subsequent write requests received by the storage system against the second volumes in the storage system after storing the data in the first volume, each write request having a target volume which is one of the second volumes; and in response to each one write request of the write requests, determining whether the target volume of the one write request is write-prohibited or not, and performing the one write request only if the target volume is not write-prohibited. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
