摘要： Several methods and apparatus to single XOR operation weaver reconstruction of a failed drive of a raid are disclosed. A failed drive of the drive group implemented in a WEAVER code with an (n,t,t) layout is determined. A set of scatter/gather lists is produced from a number of the other drives of the drive group. A scatter/gather list is created by modifying a pointer data of the set of scatter/gather lists. An additional scatter/gather list is generated from the set of scatter/gather lists. A single XOR operation is performed on the data segment, the parity segment, the additional data segment and the additional parity segment to form a resulting scatter/gather list including a resulting data segment and a resulting parity segment. The resulting data segment and the resulting parity segment are written as sequenced in the resulting scatter/gather list to a replacement drive.

摘要： A method, apparatus, and system of a priority command queues for low latency solid state drives are disclosed. In one embodiment, a system of a storage system includes a command sorter to determine a target storage device for at least one of a solid state drive (SSD) command and a hard disk drive (HDD) command and to place the command in a SSD ready queue if the SSD command is targeted to a SSD storage device of the storage system and to place the HDD command to a HDD ready queue if the HDD command is targeted to an HDD storage device of the storage system, a SSD ready queue to queue the SSD command targeted to the SSD storage device, and a HDD ready queue to queue the HDD command targeted to the HDD storage device.

摘要： A method and apparatus for quiescing a system storage device wherein cache lines associated with a system storage device to be quiesced are flushed using a stripe lock mechanism to find and flush cache data associated with the given system storage device. Dirty cache lines are associated with a stripe lock, and that stripe lock will be in the active state or the clearing state. The stripe locks are also maintained on a linked list per a system storage device. In the normal life cycle of a stripe lock, if the partner controller requests a lock over part of the extent of an active lock, the active lock will go to the clearing state. Data in the extent of the now clearing lock is flushed. For performing a quiesce, stripe locks for the given system storage device are set to clearing on a plurality of controllers, thus causing the flush. The quiesce mechanism then only needs to wait until stripe locks have been cleared for the system storage device.
