摘要： Embodiments of the present invention provide methods and systems for leadership allocation in a distributed computer system. In certain embodiments of the present invention, a leader-election-service process runs within each node of a distributed computer system, together cooperatively providing a distributed-leader-election service. The distributed-leader-election service employs a distributed consensus service to manage distributed state information related to roles and leadership allocation within a distributed computer system. Client processes within each node interface with the leader-election-service process of the node in order to assume leadership of particular roles within the distributed computer system. Leadership-allocation management is thus centralized, within each node. In alternative embodiments, the distributed-leader-election service may be implemented as a collection of library routines that run in the context of client processes.

摘要： In one embodiment a storage controller comprises a processor, a computer readable storage medium coupled to the processor, and logic instructions in the memory module which, when executed by the processor, configure the processor to receive, in a quality of service module, a first command request from a host initiator port, associate a time-out threshold with the first command request, determine, in the quality of service module, whether an available priority queue can release the first command request for execution by a scheduling module within the time-out threshold; and in response to a determination that an available priority queue can release the first command request for execution within the time-out threshold, assign the first command request to the available priority queue.

摘要： A disk array data storage system has a plurality of storage disks and a disk array controller for coordinating transfer of user data to and from the storage disks. A memory manager is provided to manage memory allocation and data storage on the disk array. The memory manager maintains a sufficient quantity of hot spare storage space that can be made available for reconstructing the user data and restoring redundancy in the event one of the storage disks fails. Until a disk fails, however, the memory manager uses the hot spare space to store user and redundant data while guaranteeing that the storage space can be used for rebuilding following a storage disk failure. In this manner, all storage disks in the array are used to store user data, and additionally to maintain storage space that can be easily made available for purposes of hot spare in the event of disk failure.

摘要： A method is provided for operating on a transaction object in a controller, such as a disk array controller. The transaction object maintains a roll forward log which holds action items to be performed, and a roll back log which lists action items already performed. In the event of power failure, the controller might be in the midst of a complex operation involving many action items. When power is restored, the controller determines whether to complete the operation using the roll forward log, or undo the operation using the roll back log. The method includes a simplified sequence, keyed to a single instruction of clearing the roll back log, which effectively makes this determination and thereby renders atomic the entire operation with respect to power failure.
