摘要： Methods and apparatus are provided for sensing physical parameters. The apparatus comprises a magnetic tunnel junction (MTJ) and a magnetic field source whose magnetic field overlaps the MTJ and whose proximity to the MTJ varies in response to an input to the sensor. The MTJ comprises first and second magnetic electrodes separated by a dielectric configured to permit significant tunneling conduction therebetween. The first magnetic electrode has its spin axis pinned and the second magnetic electrode has its spin axis free. The magnetic field source is oriented closer to the second magnetic electrode than the first magnetic electrode. The overall sensor dynamic range is extended by providing multiple electrically coupled sensors receiving the same input but with different individual response curves and desirably but not essentially formed on the same substrate.

摘要： An antifuse element (102) having end corners (120, 122) of a gate electrode (104) positioned directly above an active area (106) or bottom electrode. The minimum programming voltage between the gate electrode (104) and the active area (106) creates a current path through an insulating layer (110) positioned therebetween. The high electric field created at the end corners (120, 122) of the gate electrode (104) results in a breakdown and rupture of the insulating layer (110) at points directly beneath the end corners (120, 122). This localization of the insulating layer (110) at the corners (120,122) provides for lower post program resistance and variation, and faster programming at a lower programming power. The antifuse elements (102) when integrated into an array (300, 320, 400, 550) provide for increased packing density. The array is fabricated to include multiple active areas (304) for individual antifuse element (302) programming or a common active area (324,405,426,506) for multi-element programming.

摘要： A system for ensuring availability using volume server sets in a storage environment employing distributed block virtualization includes a plurality of volume servers, one or more volume clients, one or more physical block devices and a volume server manager. The volume server manager may be configured to designate the plurality of volume servers as a volume server set with an associated volume server set management policy, and to verify each volume server in the volume server set has access to storage within each block device. In addition, the volume server manager may be configured to designate a first volume server of the volume server set to aggregate storage within the block devices into a logical volume, to make the logical volume accessible to the volume clients, and to share configuration information about the volume with the other volume servers of the volume server set.

摘要： A system and to prevent data corruption due to split brain in shared data clusters includes two or more nodes of a cluster, a shared storage device, and an update manager. The update manager may be configured to maintain a local persistent store corresponding to each node of the cluster. On receiving an update request directed to the shared storage device from a first node, the update manager may be configured to redirect the update to the local persistent store corresponding to the first node. The update manager may be further configured to verify a cluster membership status of the first node, and to transfer the contents of the update from the local persistent store to the shared storage device if the cluster membership verification succeeds.

摘要： Various systems and methods for maintaining write order fidelity in a distributed environment are disclosed. One method, which can be performed by each node in a cluster, involves associating a current sequence number with each of several write operations included in a set of independent write operations. In response to detecting that one of the write operations in the set is ready to complete, a new sequence number is selected, and that new sequence number is thereafter used as the current sequence number. None of write operations in the set is allowed to return to the application that initiated the write operations until the new sequence number has been advertised to each other node in the cluster. The method also involves receiving a message advertising a first sequence number from another node in the cluster, and subsequently using the first sequence number as the current sequence number.

摘要： A disk array has a plurality of disks, a disk array controller for coordinating data transfer to and from the disks, and a RAID management system for mapping two different RAID areas onto the disks. The RAID management system stores data in one of the RAID areas according to mirror redundancy, and stores data in the other RAID area according to parity redundancy. The RAID management system then shifts or migrates data between the mirror and parity RAID areas on the disks in accordance with a predefined performance protocol, such as data access recency or access frequency.
