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.

Abstract: Examples of techniques for processing I/O operations in a channel are disclosed. In one example implementation according to aspects of the present disclosure, a computer-implemented method may include: copying, by a system assist processor, a subchannel of the channel into a lower portion of a channel communication area responsive to receiving the I/O operation; copying, by the system assist processor, channel program information from a designated starting location in a customer memory into a control block; building, by the system assist processor, a starting channel communication area into a top portion of the control block; queuing, by the system assist processor, the control block to a queue for the channel; processing, by the channel, the I/O operation responsive to retrieving the control block from the queue.

Abstract: Embodiments relate to controlling a temperature of a solid state memory device using queue depth management by monitoring an operating temperature of each of a plurality of solid state drives of the solid state memory device. Based on a determination that the operating temperature of one of the plurality of solid state drives exceeds local device threshold values, the method includes receiving an indication that one or more local measures have been taken by the solid state memory device. Based on a determination that the operating temperature of one of the plurality of solid state drives exceeds a secondary global threshold value, the method includes reducing a queue length for the solid state memory device.
