Abstract: A data storage system architecture for accessing data, having a plurality of data storage subsystems coupling to a host for receiving an I/O request from the host, is provided. Each of the plurality of the data storage subsystems has: a redundant array of independent disks layer (RAID layer) for generating a plurality of media extents; a virtualization module for generating one or more virtual volumes (VVs); an on-board load balance (OBLB) module for offering a data access interface between the host and the data storage system architecture to parse the I/O request into at least one sub-I/O request; and a media extent server (ME server) module to receive the at least one sub-I/O request and to determine the validity of the at least one sub-I/O request. Accordingly, the host is able to issue I/O requests to any one of the data storage subsystems.

Abstract: The invention discloses a method and controller for processing data multiplication in a RAID system. Map tables are generated for all values in a field, respectively. The length of an XOR operation unit is chosen to be appropriate w bits (e.g., 32 bits or 64 bits). One or several XOR operation units form a multiplication unit of a data sector. When computing on-line, data in a disk drive of a disk array are performed with XOR operations in accordance with one of the map tables using an XOR operation unit as one unit while computing on the multiplication unit to obtain a product of multiplication.Making use of the RAID system established according to the disclosed method, only XOR operations are required to compute parity data or recover damaged user data. Moreover, several calculations can be performed simultaneously. Therefore, the efficiency of the RAID system can be effectively improved.

Abstract: Method and apparatus for performing volume replication using a unified architecture are provided. Each volume has an exclusive volume log table (VLT) and an exclusive volume block update table (VBUT). The VLT is mainly used for recording the relationship between two volumes of a mirroring pair, and the VBUT is used for tracking the state of each data block of the volume itself. By means of the cross operations and applications between the VLT and the VBUT, various volume replication processes such as volume copying and volume mirroring can be enabled under a unified architecture. For each volume, different replication relationships with other volumes can be handled merely by administering its two exclusive tables. The method and the apparatus provided by the present invention can simplify the architecture for synchronization replication and reduce the burdens of administrating tables, thereby making the operation of a storage system more efficient.
