Abstract:
A data storage method for a plurality of RAID systems includes an SAS expander recording information of failure of a disk of a plurality of RAID systems when failure of the disk is detected and reporting the information of failure of the disk to the RAID system server when the RAID system server sends a polling message to the SAS expander or tries accessing the failed disk. In response to the failure information of the failed disk from the SAS expander, the RAID system server sends a command to the SAS expander, to replace the disk with a hot spare disk.
