Fault tolerant disk management system which tests failed disks during varied time intervals which are based upon the criticality associated with the failed disks

摘要: A fault tolerant disk management system supports compound disks which are mirrored, so as to tolerate single point faults in any one physical of the disk. The further minimizes exposure data stored on such a arising from additional failures other may be implemented software method for removing logical without breaking up or mirror part. removed then reinserted into and after repair. Further, provides responses varied accordance with an indication criticality each system.
