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： Systems, methods, and computer readable media for triggering and coordinating pool storage reclamation are disclosed. According to one example, the method includes receiving an issued hint triggered by the execution of a data storage optimization operation applied to a mapped logical unit (MLU), wherein the MLU is one of a plurality of MLUs residing in a storage array, and computing an unused portion amount of an allocated storage space in the MLU, wherein the allocated storage space comprises a plurality of slices. If the unused portion amount exceeds a predetermined threshold value, detecting at least one of the slices to be released from the allocated storage space. The method also includes transferring data contained in a detected slice to at least one of the remaining slices in the allocated storage space, and removing the detected slice from the allocated storage space in the MLU to a common storage pool in the storage array, wherein the removed slice is allocated to any one of the plurality of MLUs.

摘要： A method is used for managing snapshot mount points in storage systems. A request to resize a snapshot mount point is received and a file object associated with the snapshot mount point is retrieved. The file object is analyzed to determine a file attached to the snapshot mount point and a file ID is determined for an underlying file associated with the determined file. The file associated with the file ID is resized.

摘要： The present invention provides a method for providing snapshots of data at different times and for performing rollbacks to a selected snapshot that does not result in any subsequent snapshots being rendered unusable. The method includes a mapping mechanism wherein when a map entry for a block being written to for the first time during a session exists, then another map entry is created and all later sessions are applied to it. When a map entry for the block does not exist, a new map entry is provided and all prior sessions are applied to it.

摘要： Described are techniques for determining noteworthy events. A client performs a first call to a first routine having a first interface. The first interface includes a first set of input parameters specifying noteworthiness criteria indicating which event occurrences in a sequence of event occurrences are noteworthy. The client performs a second call to a second routine having a second interface to record an event occurrence of the sequence. The second routine perform processing returning information to the client including an indicator value denoting whether the event occurrence is noteworthy. In response to receiving the indicator value, the client may perform an action if the indicator value denotes that the event occurrence is noteworthy.
摘要翻译：描述的是确定值得注意的事件的技术。客户端对具有第一接口的第一例程执行第一次调用。第一接口包括第一组输入参数，其中规定了值得注意的事件发生顺序中哪些事件出现的值得注意的标准。客户端对具有第二接口的第二例程执行第二次调用，以记录序列的事件发生。第二例程执行向客户返回信息的处理，包括表示事件发生是否值得注意的指标值。响应于接收到指示符值，如果指示符值表示事件发生值是值得注意的话，客户端可以执行动作。
