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： 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： Extent migration is provided in a data storage environment configured for synchronous replication between a primary and secondary pair of storage entities, each having tiered storage devices. In one embodiment, by way of example only, a migration instruction is sent, by the primary storage entity, to the secondary storage entity, the migration instruction including a time delta approximately equal to a time of an intended migration at the primary storage entity adjusted for a transmission time such that the primary and secondary storage entities conduct the extent migration at approximately a same time.

摘要： A method for migrating extents between extent pools in a tiered storage architecture maintains a data access profile for an extent over a period of time. Using the data access profile, the method generates an extent profile graph that predicts data access rates for the extent into the future. The slope of the extent profile graph is calculated and used to determine whether the extent will reach a migration threshold within a specified “look-ahead” time. If so, the method calculates a migration window that allows the extent to be migrated prior to reaching the migration threshold. In certain embodiments, the method determines the overall performance impact on the source extent pool and destination extent pool during the migration window. If the overall performance impact is below a designated impact threshold, the method migrates the extent during the migration window.
