Abstract: In a storage system architecture having two storage virtualization controllers (SVCs) that operate in an active-active mode, the corresponding relationships between storage addresses in the two buffers of the two SVCs are pre-determined. When a non-owner SVC that does not have an ownership over a logical disk (LD), receives an I/O request from a host, the non-owner SVC will inquire of the other SVC having the ownership, about associated address information, and then the non-owner SVC that does not have the ownership over the LD will perform, according to the associated address information, the I/O request from the host. Therefore, data synchronization operation for mutually backing up data between the two SVCs can be fast achieved. Also, it allows the host to issue a data access request to any one of the SVCs, thus improving performance of the storage system.

Abstract: A method for remote asynchronous volume replication and apparatus therefor. Asynchronous replication is applied to handle data changes on the source volume on the local site incurred by Host IO requests. In coordination with the “point-in-time differential backup” technology, the original data in the block to be written by a host IO request will be backuped to Source BAS on the local site (backup-on-write operation) only when the original data being written into the block of the source volume is different from the data of the corresponding block of the destination volume on the remote site. As a result, once a new data is written into the source volume completely, the host will be responded that its Host IO request is completed. Therefore, the data necessarily transmitted to the destination volume can be minimized, and the problem of remote data transmission limited by network bandwidth can be prevented effectively.

Abstract: A 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 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 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.

Abstract translation: 提供了一种使用统一架构执行卷复制的方法和装置。 每个卷都有一个独占卷日志表（VLT）和一个排他卷块更新表（VBUT）。 VLT主要用于记录两个镜像对之间的关​​系，VBUT用于跟踪卷本身的每个数据块的状态。 通过VLT和VBUT之间的交叉操作，可以在统一架构下启用各种卷复制过程，如卷复制和卷镜像。 具体来说，对于每个卷，可以仅通过管理其两个独占表来处理与其他卷的不同复制关系。 因此，本发明提供的方法和装置可以有利地简化用于同步复制的架构，并减少管理表的负担，从而使存储系统的操作更有效率。

Abstract: A redundant controller storage virtualization subsystem performing host-side IO rerouting and dynamic logical media unit reassignment. In one embodiment, the assignment of logical media unit owner can be dynamically reassigned to the receiving storage virtualization controller which was originally not the logical media unit owner such that the receiving storage virtualization controller becomes new logical media unit owner to execute the IO request. In another embodiment, the dynamic logical media unit reassignment can be performed according to the operating condition(s) of the storage virtualization system so as to improve the performance of the storage virtualization system. In a further embodiment, the controller storage virtualization subsystem can perform host-side IO rerouting when the timing for performing dynamic logical media unit reassignment is not reached.
