摘要： A method for generating a virtual volume (VV) in a storage system architecture. The architecture comprises a host and one or more disk array subsystems. Each subsystem comprises a storage controller. One or more of the subsystems comprises a physical storage device (PSD) array. The method comprises the following steps: mapping the PSD array into a plurality of media extents (MEs), each of the MEs comprises a plurality of sections; providing a virtual pool (VP) to implement a section cross-referencing function, wherein a section index (SI) of each of the sections contained in the VP is defined by the VP to cross-reference VP sections to physical ME locations; providing a conversion method or procedure or function for mapping VP capacity into to a VV; and presenting the VV to the host. A storage subsystem and a storage system architecture performing the method are also provided.

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： A redundant external storage virtualization computer system. The redundant storage virtualization computer system includes a host entity for issuing an IO request, a redundant external SAS storage virtualization controller pair 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 pair through a SAS interconnect. The redundant storage virtualization controller pair includes a first and a second SAS storage virtualization controller both coupled to the host entity. In the redundant SAS storage virtualization controller pair, when the second storage virtualization controller is not on line, the first storage virtualization controller will take over the functionality originally performed by the second storage virtualization controller.

摘要： The present inveniton provides a method for improving data reading performance and a controller performing the same. After a read request is sent to a storage device, the processing time of the read request starts to be counted. If the read request does not successfully read data in a predetermined time period, redundant data identical to the read data is generated in order to achieve the action of reading data. The read request process is still ongoing while generating the redundant data. When the data is read or generated successfully by either of the read request process or the redundant data generating process, the data is returned to a request unit.

摘要： This specification discloses a method of managing data snapshot images in a storage system. The method includes the steps of: establishing a section allocation system that includes at least a media extent; establishing a section allocation table and a block association set in the media extent, wherein the section allocation table has a field containing information pointing to the block association set and the block association set corresponds to a Source Volume as the basis for performing a snapshot backup thereof; establishing a block association table in the block association set, wherein the block association table is used to store cross-reference information in order to correspond to backup data with the original storage addresses; and copying the data before updating the data into the section association set, when the data in the Source-Volume need to be updated.
