In certain, currently available data-storage systems, incoming commands from remote host computers are subject to several levels of command-queue-depth-fairness-related throttles to ensure that all host computers accessing the data-storage systems receive a reasonable fraction of data-storage-system command-processing bandwidth to avoid starvation of one or more host computers. Recently, certain host-computer-to-data-storage-system communication protocols have been enhanced to provide for association of priorities with commands. However, these new command-associated priorities may lead to starvation of priority levels and to a risk of deadlock due to priority-level starvation and priority inversion. In various embodiments of the present invention, at least one additional level of command-queue-depth-fairness-related throttling is introduced in order to avoid starvation of one or more priority levels, thereby eliminating or minimizing the risk of priority-level starvation and priority-related deadlock.

Apparatus and methods for efficient queuing and dequeuing using segmented output buffers comprising sub-buffers and priority queues. Output buffers are monitored for empty sub-buffers. When a newly empty sub-buffer is discovered, a refill request is enqueued in a ranked priority queue wherein the rank of the destination priority queue is based on the number of empty-sub-buffers in the requesting output buffer. All high priority refill requests are dequeued before lower priority refill requests, thereby reducing the possibility of starvation. Optionally, by using simple dequeuing criteria, such as a FIFO discipline, instead of complex algorithms designed to improve fairness, system resources may be conserved thereby improving system throughput.
