  • Storage system and operation method of a storage system
    Patent number: 8775735
    Abstract: A storage system includes a redundant array of independent disks (RAID), a file subsystem, and a multiple device control unit. The RAID includes a plurality of disks and a bitmap. The file subsystem is used for executing a write command and a trim command. The multiple device control unit does not execute a first synchronization operation on the plurality of disks during the RAID is built, does not execute a second synchronization operation on expansion capacity of the plurality of disks during the RAID is expanded, executes a third synchronization operation on at least one added disk according to the blocks of the plurality of disks occupied by the data during the RAID is reshaped, and/or executes a corresponding operation on at least one added disk according to the blocks of the plurality of disks occupied by the data during the RAID is recovered.

  • AUTOMATIC REMAPPING IN REDUNDANT ARRAY OF INDEPENDENT DISKS AND RELATED RAID
    Publication number: 20130179726
    Abstract: A method of performing automatic remapping in a redundant array of independent disks (RAID) includes issuing a read command for performing a read operation to read data from a hard disk of the RAID, and remapping a bad sector the data is located in to an unused good sector of the hard disk when the bad sector is encountered during the read operation.
