摘要： A system and method related to maintaining consistency of replicated data in a data storage environment. The system handles Input/Output (IO)-Requests in a data storage environment having a server and production data stored on a data storage volume on a data storage system. A copy of the production data is stored on another data storage volume of a second data storage system, wherein IO-Requests to update production data are handled so that the data copy is consistent with the production data after processing the IO-Request.

摘要： A method is used in managing restore operations in storage systems. A state of a logical object is retrieved and a second logical object is placed in a pre-step mode. An instantaneous restore operation between the first logical object and the second logical object is performed. Changed data extents in the first logical object are identified. Data-less writes are sent to any identified extents in the first logical object.

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 storage system uses a block-level file system to manage physical storage of data blocks of logical units, the file system being mounted on an owning one of a set of storage processors. The storage processors redirect received storage requests to the owning storage processor, and periodically the amount of redirection is evaluated. If the amount of redirection is higher than a threshold, then the file system is dismounted at the owning storage processor and mounted at another storage processor to reduce the amount of redirection.
摘要翻译：存储系统使用块级文件系统来管理逻辑单元的数据块的物理存储，该文件系统被安装在一组存储处理器中的所有的一个上。存储处理器将接收的存储请求重定向到拥有的存储处理器，并且周期性地评估重定向的量。如果重定向的数量高于阈值，则文件系统在所有的存储处理器上被卸载并安装在另一个存储处理器上以减少重定向的数量。

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.
