<p>A message buffer in an I/O subsystem allows asynchronous buffering of messages between I/O processors which control I/O devices and an I/O control processor, which executes issued I/O instructions. The message buffer is located in the I/O control processor, thereby avoiding a lengthy message path through the main storage of a main processor served by the I/O system.</p>
