摘要： A method and an 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. Specifically, for each volume, different replication relationships with other volumes can be handled merely by administering its two exclusive tables. Hence, the method and the apparatus provided by the present invention can advantageously simplify the architecture for synchronization replication and reduce the burdens of administrating tables, thereby making the operation of a storage system more efficient.

摘要： The invention relates to a method, a storage subsystem and system for improving data writing efficiency. When writing data, if a predetermined N number of data or fewer than the predetermined N number of data are yet written after waiting a specific time period, the data writing I/O request is regarded as completed. The corresponding resources are then released. The N number of yet written data and the related writing information are stored in a non-volatile memory (NVRAM), so that when there is a sudden power cut or power failure happens that interrupts the data writing, the process can be resumed after the power supply is turned back on.

摘要： Disclosed is a redundant storage virtualization subsystem (SVS) having branching functionality The SVS comprises a first and a second storage virtualization controller (SVC) and a physical storage device (PSD) array. A first and a second data path are provided between the first SVC and the PSD array passing through a first and a second signal integrity enhancing device (SIED), respectively, and configured as a first pair of redundant data paths. A third and a fourth data path are provided between the second SVC and the PSD array passing through the second and the first SIED, respectively, and configured as a second pair of redundant data paths. In view of the PSD array, the first and fourth data paths form a third redundant data path pair for a PSD, and the third and second data paths form a fourth redundant data path pair for a PSD. In a redundant data path pair, when one of the data paths is inaccessible while the other of the data paths is accessible by the SVCs to the PSD array, data access by the SVCs to the PSD array through said redundant data path pair will be performed through the accessible data path. In another embodiment, the SIEDs are provided on separate circuit boards from the SVCs. In a further embodiment, the SIEDs can be omitted.

摘要： Method for accessing data in a storage system architecture, the architecture comprises at least one disk array subsystem, comprising the following steps. Provide a SAS for managing a first and a second media extent (ME) the at least one subsystem. Obtain a location index corresponding to a host LBA via a BAT. Obtain a location information of a physical section located in the first ME corresponding to the location index via a physical section to virtual section cross-referencing functionality. Update the cross-reference in the cross-referencing functionality so that the location information obtained from the cross-referencing functionality corresponding to the location index is the location information of the second physical section. A host IO request addressing the host LBA accesses data in the second physical section utilizing the location information of the second physical section.

摘要： A redundant storage virtualization computer system is provided. The redundant storage virtualization computer system comprises a host entity for issuing an IO request, a redundant storage virtualization controller set coupled to the host entity for performing an IO operation in response to the IO request issued by the host entity, and a plurality of physical storage devices for providing storage space to the computer system. Each of the physical storage devices is coupled to the redundant storage virtualization controller set. The redundant storage virtualization controller set comprises a first and a second storage virtualization controller both coupled to the host entity, the storage virtualization controllers communicate therebetween via a PCI-Express interconnect. In the redundant storage virtualization controller set, a storage virtualization controller will take over the functionality originally performed by the alternate storage virtualization controller when the alternate storage virtualization controller is not on line.
