Abstract

A method for creating firmware-dedicated queues for storage system multi-queue operation is provided. The method includes providing a controller to manage a plurality of input/output (IO) operations between hosts and virtual disks by issuing the plurality of IO operations to a plurality of queues comprising submission queues and completion queues, wherein one or more submission queues are mapped to each completion queue. The method also includes configuring at least one submission queue as a FW-dedicated queue for submitting internal IO operations initiated by firmware (FW) associated with the controller. The method further includes adding one or more parameters in FW-queue-related fields in a controller device state table for each device of the virtual disks. The one or more parameters include at least a first parameter to enable the FW-dedicated queue for only submitting the internal IO operations in parallel with other queues to the device.
