    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: 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.

    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: 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: Embodiments provide a strategy for computing the motions of a mobile robot operating in an obstacle-laden environment without requiring prior knowledge of the distribution of obstacles in the environment or knowing the trajectory of a target tracked by the robot. Embodiments provide an algorithm that governs the motion of the observer robot based on measurements of the target's position and the location of obstacles in the environment. The algorithm computes a description of the geometric arrangement between the target and the observer's visibility region produced by the obstacles and computes a continuous control rule using this description. Embodiments employ an escape-path tree data structure to categorize the target's possible modes of escaping from the observer robot's sensors and use the escape-path tree to determine the target's shortest escape path.
