    • 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.
    • 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。

    • A controller capable of self-monitoring, a redundant storage system having the same, and its method are proposed. Each controller is arranged with a self-monitoring operating circuit and a watchdog unit. The self-monitoring operating circuit can periodically issue a confirmation signal to the watchdog unit. The watchdog unit comprises a counter unit for counting a predetermined time interval, and if it does not receive the confirmation signal issued by the self-monitoring operating circuit over the predetermined time interval, it will send out an output signal to the self-monitoring operating circuit. The self-monitoring operating circuit will then generate a plurality of global reset signals to shut down the entire operation of the controller. Another controller will take over the functions of the shut-down controller.
    • 提出了一种能够进行自我监控的控制器,具有相同功能的冗余存储系统及其方法。 每个控制器配置有一个自监控操作电路和看门狗单元。 自监视操作电路可以周期性地向看门狗单元发出确认信号。 看门狗单元包括用于对预定时间间隔进行计数的计数器单元,并且如果在预定时间间隔内没有接收到由自监视操作电路发出的确认信号,则其将向自监视操作发送输出信号 电路。 然后,自监视操作电路将产生多个全局复位信号以关闭控制器的整个操作。 另一个控制器将接管关闭控制器的功能。

    • 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.
    • 公开了一种包括多个SVS的存储虚拟化子系统(SVS)架构,每个SVS包括至少一个存储虚拟化控制器(SVC),并且在一些情况下包括附接到SVC的物理存储盘(PSD)阵列。 配置第一和第二数据访问路径通过SVS以形成SVS体系结构,使得当一个路径失败时,另一个可被视为替代。 第一路径中的SVS以第一序列连接,并且第二路径中的SVS以与第一路径不同的第二序列连接。 在另一个实施例中,每个SVS包括多个冗余配置的SVC,而不是一个SVC。 形成的第一路径通过第一组SVC,并且形成第二路径穿过不同的第二组SVC。
