    摘要： An n-way parity protection technique enables recovery of up to n storage device (e.g., disk) failures in a parity group of a storage array encoded to protect against n-way disk failures. The storage array is created by first configuring the array with m data disks, where m=p−1 and p is a prime number and a row parity disk. n−1 diagonal parity disks are then added to the array. Each diagonal parity set (i.e., diagonal) is associated with a slope that defines the data and row parity blocks of the array that are included in the diagonal. All diagonals having a common slope within a parity group are organized as a diagonal parity class. For each diagonal parity class, a diagonal parity storage disk is provided to store the diagonal parity.

    摘要： A method and system for recovering data from a “sick” disk are described. One embodiment of the invention relates to a RAID-based storage system that predicts the failure of a disk (e.g., a “sick” disk) in a RAID disk group. Accordingly, the storage system allocates a target disk, selected from several spare disks, to replace the “sick” disk in the RAID disk group upon completion of a disk-to-disk copy operation. Once a target disk has been allocated, a disk-to-disk copy operation is initiated to copy data from the “sick” disk to the target disk, thereby preventing the need to reconstruct data on the “sick” disk if the “sick” disk actually fails. During the disk-to-disk copy operation, client-initiated disk access operations continue to be serviced. Upon completion of the disk-to-disk copy operation, the storage system reconfigures the RAID disk group by swapping the target disk with the “sick” disk.

    摘要： In one embodiment, a method for processing a client request for content comprises receiving, at an intermediary network node, a client request for content on a network. The client request is associated with a set of attributes indicating a requirement to process the requested content by multiple designated applications prior to transferring the requested content to a client. The method further comprises searching, at the intermediary network node, a content cache for matching content conforming to the processing requirement, and determining, at the intermediary network node, whether the matching content is currently valid. If this determination is positive, the matching content is transferred to the client.
