Abstract:
1. In a data storage environment having a first and second data storage system, and production data being stored on the first data storage system, a method for reallocating memory resources for transfer of data across a network link in the data storage environment during a replication of the production data to produce a copy of the production data on the second data storage system, the method comprising the steps of: inspecting copy sessions forming a copy session group operating in the data storage environment to determine the size and number of buffers each copy session of the copy sessions is using; determining whether to abort a copy session of the copy sessions to contribute the buffer space of the aborted copy session to available buffer space; and based on the determining, restarting the aborted copy session and another copy session with buffer space allocated from the available buffer space; wherein the determining whether to abort the copy session is based on the inspection.
