ABSTRACT:
The present invention aims to provide a high-reliability, low-cost disk array by emulating an ATA drive so that it can be used in the same way as an FC drive. To achieve this object, a disk array system of the present invention includes: a storage device having a logical unit logically set therein; the storage device includes: a plurality of disk devices having a first interface; and an interface converter converting between signals of the first interface adapted for the disk device and signals of a second interface adapted for the control device. The interface converter includes: a response time monitor portion for monitoring a time until a response is received from the disk device according to the data input/output request; and a notification issue portion for issuing to the control device a notification about an operative state of the disk device according to the monitored response time.
