    摘要: Systems and methods for optimizing deduplication in a data storage system are provided. The method comprises associating a first name with first data blocks including first content stored in a data storage system, wherein the first name is associated with the first data blocks by way of a reference to a first meta file that points to a data file which points to the first data blocks; storing a first signature derived from the first content in an indexing data structure, wherein the first signature is used to associate the first name with the first data blocks and as means to verify whether a second content is a duplicate of the first content, based on value of a second signature derived from the second content.

    摘要: Machines, systems and methods for task management in a computer implemented system. The method comprises registering a task with brokers residing on one or more nodes to manage the execution of a task to completion, wherein a first broker is accompanied by a first set of worker threads co-located on the node on which the first broker is executed, wherein the first broker assigns responsibility of execution for the task to the one or more worker threads in the first set of co-located worker threads, wherein in response to a failure associated with a first worker thread in the first set, the first broker reassigns the responsibility of execution for the task to a second worker thread in the first set, wherein in response to a failure associated with the first broker, a second broker assigns responsibility of execution for the task to one or more co-located worker threads.

    摘要: A two-phase process FlashCopy operation is provided that can be used to aid in the formation of consistency groups across multiple storage control units. In the first phase, preparations to create a new consistency group are made “revertible” by write-inhibiting the source volumes through “Establish-FlashCopy-revertible” commands. If the preparation of any volume within the consistency group fails, a “Withdraw-FlashCopy-revert” command may be executed, thereby causing a retention of the prior FlashCopy point-in-time copy. In the second phase, executed if all preparations are successful, a “Withdraw-FlashCopy-commit” command may be executed to remove all write-inhibit indicators, complete the creation of the new FlashCopy point-in-time copy and secure the new consistency group. Write requests to the FlashCopy source volumes may then be received and processed without risking corruption of the new consistency group on the Flashcopy target volumes.
