Abstract: This invention discloses a storage visualization subsystem and system with host-side redundancy via SAS connectivity. The I/O interconnect interface between the storage visualization controller and the host is a serial-attached SCSI (SAS) interface. At least one SAS expander is inserted on the I/O interconnect path of the host side to provide the function of device expansion. Or, a built-in virtual SAS expander is disposed inside the storage virtualization controller to provide multiple virtual IDs for each SAS port. When one controller in the storage virtualization controller pair malfunctions or fails, the invention provides solutions in accord with different embodiments so that the surviving controller can inherit the ID of the failed one. Thus, the host can keep functioning normally as it is not aware of any change in the device status.

Abstract: A method for remote asynchronous volume replication and apparatus therefore are disclosed. Asynchronous replication is applied to deal with 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 data is subjected to 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 on the remote site can be minimized, and the problem of remote data transmission limited by network bandwidth can be prevented effectively, thereby keeping the operation performance of the storage system at a better level.
Abstract translation: 因此，公开了用于远程异步卷复制的方法和装置。 应用异步复制来处理主机IO请求引起的本地站点上的源卷上的数据更改。 与“时间差异备份”技术配合，只有当原始数据写入源的块时，数据才会被备份到本地站点上的源BAS（备份写操作） 卷与远程站点上目标卷的相应块的数据不同。 因此，一旦将新数据完全写入源卷，主机将响应其主机IO请求完成。 因此，能够将发送到远程站点的目的地卷的数据最小化，能够有效地防止由网络带宽限制的远程数据传输的问题，从而保持存储系统的操作性能更好。

Abstract: Disclosed is a storage virtualization subsystem (SVS) architecture comprising a plurality of SVSs, each SVS comprising at least one storage virtualization controller (SVC), and, in some cases, a physical storage disk (PSD) array attached to the SVC. A first and a second data access path is configured passing through the SVSs to form the SVS architecture such that when one path is failed, the other can be taken as a substitution. The SVSs in the first path are connected in a first sequence and the SVSs in the second path are connected in a second sequence different from the first one. In another embodiment, each SVS comprises a plurality of redundantly-configured SVCs rather than one SVC. The first path is formed passing through a first set of SVCs and the second path is formed passing through a different second set of SVCs.

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。
