1. A method for archiving data from a server cluster to a backend data storage device via a computer network, the method comprising:

  • placing a complex of archive storage controllers in the network, the complex including a master archive storage controller having a speed matching buffer set module;

    the server cluster executing backup logic programmed to send a bulk input/output (I/O) request for a greater than a predetermined-size transfer of archive data to the master archive storage controller; and

    the speed matching buffer set module programmed, responsive to receiving the bulk I/O request, to identify a target transfer rate as defined by the bulk I/O request or by a predetermined relationship to I/O load, to identify identifying a speed matching buffer set of two or more of the archive storage controllers in the complex that are available, for lack of a predefined resource constraint characterized in terms of operational state, data storage capacity, processor capability, bandwidth, or utilization, to collectively transfer the bulk I/O request at the target transfer rate, and to send a bulk I/O response used by the server cluster to modify the bulk I/O request by apportioning it into parallel I/O requests to the speed matching buffer set.
