摘要： Provided are a computer program product, system, and method for determining whether to extend a drain time to copy data blocks from a first storage to a second storage. A data structure is generated indicating data blocks in the first storage to copy to the second storage. A drain operation is initiated to copy the data blocks indicated in the first storage to the second storage for a drain time period. Write requests to the data blocks indicated in the data structure are queued during the drain time period, wherein the queued write requests are not completed while queued. Metric information based on the writes that occur to data blocks in the first storage are gathered during the drain time period; and in response to expiration of the drain time period, a determination is made from the gathered metric information of whether to continue the drain operation or terminate the drain operation.

摘要： A priority-based method for replicating data is disclosed herein. In one embodiment, such a method includes providing a primary storage device and a secondary storage device. Multiple storage areas (e.g., volumes, groups of volumes, etc.) are designated for replication from the primary storage device to the secondary storage device. A priority level is assigned to each of the storage areas. Using these priority levels, the method replicates the storage areas from the primary storage device to the secondary storage device in accordance with their assigned priority levels. Higher priority storage areas are replicated prior to lower priority storage areas. A corresponding computer program product and system are also disclosed herein.

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： A method for concurrently converting a standard volume to a thin-provisioned volume includes initially establishing metadata for a thin-provisioned volume. The method then updates the metadata for the thin-provisioned volume to point to extents residing in a standard volume. The method then suspends I/O to metadata for the standard volume. Upon suspending the I/O, the method migrates control of the extents in the standard volume from a standard-volume control algorithm to a thin-provisioned-volume control algorithm. The method then resumes the I/O to the metadata for the thin-provisioned volume. Using this technique, standard volumes may be rapidly converted to thin-provisioned volumes while minimally disrupting I/O to the volumes. A corresponding apparatus and computer program product are also disclosed and claimed herein.
