摘要： In one embodiment, pursuant to migrating the data from the first to the second storage medium, the data is allocated to the second storage medium while retaining an allocation of the data in the first storage medium. If the data is migrated from the second storage medium back to the first storage medium, the data is pointed to the allocation of the data in the first storage medium to alleviate data movement from the second storage medium to the first storage medium. If the allocation of the data in the first storage medium is determined to be needed for other data, the allocation of the data in the first storage medium is freed.
摘要翻译：在一个实施例中，根据将数据从第一存储介质迁移到第二存储介质，数据被分配给第二存储介质，同时保留数据在第一存储介质中的分配。如果数据从第二存储介质迁移回到第一存储介质，则数据被指向在第一存储介质中的数据分配，以缓解从第二存储介质到第一存储介质的数据移动。如果确定第一存储介质中的数据的分配对于其他数据是需要的，则释放第一存储介质中的数据的分配。

摘要： A method for managing extents in a data storage system includes monitoring usage statistics for an extent residing on one or more powered-up storage devices. In the event the extent has not been accessed for specified period of time (as determined from the usage statistics), the method automatically compresses the extent and migrates the extent to an intermediate repository. Once the amount of data in the intermediate repository reaches a specified level, the method migrates the extent from the intermediate repository to one or more normally powered-down storage devices. If I/O is received for the extent while it resides in the normally powered-down storage devices or the intermediate repository, the method automatically migrates the extent from the normally powered-down storage devices or the intermediate repository to the normally powered-up storage devices. A corresponding apparatus and computer program product are also disclosed.

摘要： A method for more effectively distributing the I/O workload in a data replication system is disclosed herein. In selected embodiments, such a method may include generating an I/O request and identifying a storage resource group associated with the I/O request. In the event the I/O request is associated with a first storage resource group, the I/O request may be directed to a first storage device and a copy of the I/O request may be mirrored from the first storage device to a second storage device. Alternatively, in the event the I/O request is associated with a second storage resource group, the I/O request may be directed to a second storage device and a copy of the I/O request may be mirrored from the second storage device to the first storage device.

摘要： A read/write ratio for each of a plurality of data segments classified in a hot category as hot data segments is determined. Each of the plurality of hot data segments is ordered by the read/write ratio in a descending order. Each of a plurality of available SSD devices is ordered by a remaining life expectancy in an ascending order. Those of the plurality of hot data segments are matched with those of the plurality of hot data segments with those of the plurality of available SSD devices such that a hot data segment having a higher read/write ratio is provided to an SSD device having a smaller remaining life expectancy than another hot data segment having a lower read/write ratio.

摘要： A method for dynamic consistency group formation, in one embodiment, includes creating a snapshot of first data stored on a source storage system with respect to data content and data structure, copying the snapshot to a target storage system, detecting one or more write operations affecting data on the source storage system while copying the first data, detecting one or more collisions affecting the first data on the source storage system, wherein a collision occurs whenever the write operations affect the first data prior to the first data being written, setting a consistency group interval which represents an interval duration between successive snapshot create-and-copy events, and altering the consistency group interval to minimize collisions affecting data on at least one of the storage systems. Other methods for dynamic consistency group formation are also described.
摘要翻译：在一个实施例中，用于动态一致性组形成的方法包括：针对数据内容和数据结构创建存储在源存储系统上的第一数据的快照，将快照复制到目标存储系统，检测影响到的一个或多个写操作源数据存储系统上的数据，同时复制第一数据，检测影响源存储系统上的第一数据的一个或多个冲突，其中每当写入操作影响第一数据被写入之前的第一数据时，发生冲突，组间隔，其表示连续快照创建和复制事件之间的间隔持续时间，以及改变一致性组间隔，以最小化影响至少一个存储系统上的数据的冲突。还描述了用于动态一致性组形成的其他方法。
