Abstract
Systems and methods for improving the performance and reliability of a copy manager by dynamically controlling performance of concurrent extended copy tasks. In one embodiment, the number of concurrent extended copy commands which are allowed to be active within a copy manager are dynamically adjusted based upon the resources available to service the commands (e.g., buffers available to store in-transit data). For example, the total number of data buffers, together with the number of buffers required to execute a single extended copy command, may be used to constrain the number of concurrent extended copy commands which are allowed to be active in the copy manager. Extended copy commands which are not active are held in queue for later execution.
