Abstract

An example computer-implemented method may include receiving, by a general purpose processor, the I/O operation. The method may further include transmitting, by the general purpose processor, the I/O operation to a system assist processor. The method may further include transmitting, by the system assist processor, the I/O operation to an I/O channel for execution by the I/O channel, wherein transmitting the I/O operation to the I/O channel comprises queuing the I/O operation in the multi-queue. The method may further include executing, by the I/O channel, the I/O operation.
