High availability computer system and fault correction method. If a fault occurs in the current-system physical device allocated to the current-system virtual device of the virtual server, the virtualization mechanism of the physical server configures, for the standby-system virtual device of the virtual server, the standby-system physical device, as a physical device which is used at a high priority, and the virtualization mechanism distributes the request issued from the standby-system virtual device of another virtual server to a standby-system physical device, but, when such a standby-system physical device does not exist, the virtualization mechanism distributes the request to a standby-system physical device configured for high priority usage.

The present invention offers a novel control system for a multiphase motor. The control system involves energization circuitry for energizing each phase winding, and a control circuit for defining phase currents for individual phases of the motor to generate control signals applied to the energization circuitry for energization of the phase windings. When at least one phase of the motor fails, a mode selection circuit enables the control circuit to operate either in a non-correction mode or in a fault-correction mode. In the non-correction mode of operation, phase currents for phases that remain operational are maintained unmodified. In the fault-correction mode, the phase currents for the remaining phases are modified in accordance with pre-set parameters.

A fault router method and system for use in a parallel redundant network environment provide additional safeguards over traditional redundant networks.

A relatively small amount of programmable or reprogrammable logic (pro-Logic) is included in a mostly-ASIC device so that such re/programmable logic can be used as a substitute for, or for bypassing a fault-infected ASIC block (if any) either permanently or at times when the fault-infected ASIC block is about to perform a fault-infected operation (bug-infected operation). The substitution or bypass does not have to be a permanent one that is in effect at all times for the entirety of the fault-infected ASIC block. Instead affected outputs of the faulty ASIC block can be disabled from working just at the time they would otherwise initiate or propagate an error. Such fault-infected operations of the temporarily deactivated ASIC block(s) may be substituted for by appropriately programmed pro-Logic at the appropriate times. Thus, a fault-infected ASIC block that is 99% good (for example) and operates improperly just 1% of the time can continue to be gainfully used for that 99% of the time when its operations are fault free and can be blocked from having its erroneous output(s) used only in the 1% time periods (example) when its behavior is faulty. During those faulty times, a relatively small amount of the pro-Logic can be used as a fault-correcting or fault-bypassing substitute for the fault-infected ASIC block. This substitution or bypassing can be activated after initial design of the mostly-ASIC circuitry and/or after pilot production and/or mass production thereby providing for cost saving and faster time to market and/or for repair or maintenance even years after installation and use of the mostly-ASIC device.

A uniform and symmetric, double failure-correcting technique protects against two or fewer disk failures in a disk array of a storage system. A RAID system of the storage system generates two disks worth of “redundant” information for storage in the array, wherein the redundant information (e.g., parity) is illustratively derived from computations along both diagonal parity sets (“diagonals”) and row parity sets (“rows”). Specifically, the RAID system computes row parity along rows of the array and diagonal parity along diagonals of the array. However, the contents of the redundant (parity) information disks interact such that neither disk contains purely (solely) diagonal or row redundancy information; the redundant information is generated using diagonal parity results in row parity computations (and vice versa).
