    摘要： Systems, methods, and computer readable media for tracking storage pool reservations are disclosed. According to one aspect, the subject matter described herein includes a system for tracking storage pool reservations. The system includes a storage entity having data storage space for storing data, the data storage space being divided into a plurality of slices. The system also includes one or more portions of non-volatile memory, different from the data storage space, for storing slice reservation statistics and information about requests that affect slice reservation statistics, wherein storing information in the portion of non-volatile memory is an atomic operation. The system further includes a control module for receiving a request that affect slice reservation statistics, storing information about the request in the portion of non-volatile memory, performing the request, and updating the slice reservation statistics and clearing the information about the request in the portion of non-volatile memory.

    摘要： A system for performance optimization of storage allocation to virtual logical units includes a storage entity having data storage space divided into slices for storing data. A slice allocation table stores slice allocation status. A memory stores statistics regarding the allocation of slices to logical units. A management database stores information regarding the allocation of slices to logical units. An allocation module performs an allocation process in response to receiving an I/O write request. A management module performs scheduled post-I/O management processes asynchronously with allocation processes, including updating the management database to reflect the allocation of the selected slice, and updating the status of the selected slice in the slice allocation table to indicate that the post-I/O management process for the selected slice has been performed.

    摘要： Methods, systems, and computer program products for postponing bitmap transfers and eliminating configuration information transfers during trespass operations in a disk array environment are disclosed. According to one method, a clone group is stored on a disk array, the clone group including a logical unit (LUN) representing a storage partition on the disk array and a clone of the LUN, the clone being a copy of the data referenced by the LUN. The clone group is associated with a first storage processor (SP) for writing data to the disk array. Changes between the LUN and the clone are tracked by maintaining a data structure indicative of the changes in a memory associated with the first SP. The association of the clone group is changed to a second SP for writing data to the disk array without transferring the data structure to memory associated with the second SP.
