    Abstract: 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.

    Abstract: 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.

    Abstract translation: 公开了具有分支功能的冗余存储虚拟化子系统（SVS）.SVS包括第一和第二存储虚拟化控制器（SVC）和物理存储设备（PSD）阵列。 在第一SVC和PSD阵列之间提供分别穿过第一和第二信号完整性增强设备（SIED）并被配置为第一对冗余数据路径的第一和第二数据路径。 在第二SVC和PSD阵列之间提供分别通过第二SIED和第一SIED的第三和第四数据路径，并被配置为第二对冗余数据路径。 鉴于PSD阵列，第一和第四数据路径形成用于PSD的第三冗余数据路径对，并且第三和第二数据路径形成用于PSD的第四冗余数据路径对。 在冗余数据路径对中，当其中一条数据路径不可访问，而其他数据路径可由SVC访问到PSD阵列时，SVC将通过所述冗余数据路径对对PSD阵列的数据访问 通过可访问的数据路径。 在另一个实施例中，SIED被提供在与SVC的分开的电路板上。 在另一实施例中，SIED可被省略。
