    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 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: An SAS RAID head is provided to connect between at least one initiator and at least one storage device. It is a connection head possessed of the RAID function. The SAS RAID head comprises at least one SVC (or a SVC pair), a cooling module, a power supply, and/or an enclosure for accommodating and fixing the above-mentioned components. Wherein, the device-side I/O device interconnect of the SVC (or SVC pair) is the SAS interface. The invention has the flexibility to vary the numbers of initiators and storage devices connected thereto in order to satisfy the topological structures of various systems.

    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.

    Abstract: 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.
