摘要： A system, method, and computer program product for a lease-based timeout scheme that addresses fencing's shortcomings. Unlike fencing, this scheme (or protocol) enables an isolated computer to realize it is disconnected from the distributed system and write its dirty data out to storage before its locks are stolen. In accordance with the invention, data consistency during a partition in a distributed system is ensured by establishing a lease based protocol between in the distributed system wherein a client can hold a lease with a server. The lease represents a contract between a client and a server in which the server promises to respect the client for a period of time. The server respects the contract even when it detects a partition between the client and itself.

摘要： A device for treatment of spondylotic disease includes a distractor for distracting vertebral facets of first and second vertebrae located adjacent each other. The distractor includes a first abutment surface for interfacing with an inferior articular facet of the first vertebra. The distractor also includes a second abutment surface for interfacing with the superior articular facet of the second vertebra corresponding to the inferior articular facet of the first vertebra. The first and second abutment surfaces of the distractor engage with each other and are separated by a predetermined distance.

摘要： Embodiments of the present invention provide novel, reliable and efficient technique for tracking, tolerating and correcting unrecoverable errors (i.e., errors that cannot be recovered by the existing RAID protection schemes) in a RAID array by reducing the need to perform drastic recovery actions, such as a file system consistency check, which typically disrupts client access to the storage system. Advantageously, ability to tolerate and correct errors in the RAID array beyond the fault tolerance level of the underlying RAID technique increases resiliency and availability of the storage system.

摘要： A triple parity (TP) technique reduces overhead of computing diagonal and anti-diagonal parity for a storage array adapted to enable efficient recovery from the concurrent failure of three storage devices in the array. The diagonal parity is computed along diagonal parity sets that collectively span all data disks and a row parity disk of the array. The parity for all of the diagonal parity sets except one is stored on the diagonal parity disk. Similarly, the anti-diagonal parity is computed along anti-diagonal parity sets that collectively span all data disks and a row parity disk of the array. The parity for all of the anti-diagonal parity sets except one is stored on the anti-diagonal parity disk. The TP technique provides a uniform stripe depth and an optimal amount of parity information.
