摘要： In an array of data storage disks, a data validation system for data arranged in corresponding sectors of a sector group that includes a parity sector. Each user data sector in a sector group is assigned at least two of a plurality of validation fields for placement of a validation stamp. No two data sectors are assigned to identically corresponding sets of validation fields. In the parity sector, there is a parity entry in each of the validation fields created by combining all of the validation stamps in the corresponding validation field throughout the sector group. The validation fields are used to detect partially completed writes into the array of data storage disks.

摘要： A fail-over switch (100, 102) for use in a data storage system that connects each of a plurality of data storage devices (112) to each of two communication paths (126, 128). The switch (100, 102) may route requests to either of the two communication paths (126, 128). Switching may be accomplished by two switches (100, 102) connected to each other and each in connection with one of the two communication paths (126, 128). With one data storage controller (90) in communication with the data storage devices (112) over a first path (126) and a second data storage controller (92) in communication with the data storage devices (112) over a second path (128), the fail-over switch (100, 102) may be used upon detection of a malfunction on one path to switch a controller into connection with the remaining operable path so as to share that path with the other controller.

摘要： A method, apparatus, and computer program product for controlling access to a target device utilizes an initiator identifier to either permit or deny access to a selected portion of the target device (102). To that end, a message having the initiator identifier is directed from the initiator device (100) to the target device (102) to request access to the selected portion of the target device. Upon receipt by the target device, it is determined if the initiator identifier is in a permitted set of identifiers associated with the selected portion of the target device. If the initiator identifier is in the permitted set, then access to the portion (108) of the target device is permitted and the initiator can access the target in accordance with conventionally known processes.

摘要： A MOSFET (10), an op-amp (20), a comparator circuit (110), and voltage dividers (170,180) with capacitors (150,240) are employed in combination to effectuate a soft-start switch with current limiting. The transconductance of the MOSFET is employed so that no sense resistor is required. The MOSFET and op-amp are configured as a closed-loop feedback circuit in which the output of the op-amp is coupled to the gate (12) of the MOSFET and the inverting input (24) of the op-amp is coupled to the output of the soft-start switch via a voltage divider. A first RC circuit (144,250) provides a voltage to the non-inverting input of the op-amp which can be triggered to gradually rise from a value close to zero to some reference voltage so as to soft-start a load. Current limiting means are effectuated by a comparator circuit and voltage dividers (170,180) with capacitors. The current limiting means brings the MOSFET to an OFF state and the non-inverting input of the op-amp close to zero volts if the op-amp charges a second RC circuit so that the voltage drop across its capacitor exceeds a pre-determined limit-reference, and also, once the current limiting means brings the MOSFET to the OFF state, the current limiting means allows the soft-start switch to begin a soft-start power-up after a pre-determined time dependent upon the time constant of the second RC circuit.

摘要： A shared-disk cluster system includes a cluster membership manager framework which coordinates the joining or leaving among all nodes in a cluster including taking the multiple layers of involved subsystems through transitions. Subsystems are notified of transitions in particular order depending upon the transition, and all nodes' subsystems receiving a notification must process that notification prior to another layer of subsystems being notified. One of the subsystems registered for notification is an event manager in user space. The event manager carries out transfers of client services, including user applications, resulting from nodes joining and leaving the cluster. This includes a registration and launch service which registers a node, or multiple nodes, in a cluster which claims, or is assigned, responsibility for the service and provides an optional launching function which initiates the client service upon successful registration.
