摘要： A method and system for optimizing network I/O throughput is disclosed. In one embodiment, a method for optimizing an input/output (I/O) throughput for a storage network comprises measuring a service time for a storage device of the storage network in completing an I/O request serviced by a storage driver. The method also comprises determining a status of an I/O performance between the storage driver and the storage device by comparing the service time with an expected service time for the storage device in completing the I/O request, where the expected service time is calculated based on a type of the storage device and a size of the I/O request. The method further comprises adjusting a maximum queue depth associated with the storage device based on the status of the I/O performance.

摘要： A method and system of a host device hosting multiple workloads for controlling flows of I/O requests directed to a storage device is disclosed. In one embodiment, a type of a response from the storage device reacting to an I/O request issued by an I/O stack layer of the host device is determined. Then, a workload associated with the I/O request is identified among the multiple workloads based on the response to the I/O request. Further, a maximum queue depth assigned to the workload is adjusted based on the type of the response, where the maximum queue depth is a maximum number of I/O requests from the workload which are concurrently issuable by the I/O stack layer.

摘要： The invention relates to management of a plurality of I/O requests in a storage system. The host interface module is configured to receive a plurality of I/O request which includes an associated priority; create an I/O request queue for each associated priority; define a threshold value for the queue length for each of the plurality of I/O request queues; and determine if the queue length for one of the plurality of the I/O request queue corresponding to the associated priority is less than the defined threshold value for the queue length for the one of the plurality of the I/O request queues. If the queue length of the one of the plurality of I/O request queues is more than the defined threshold value for the queue then the host interface module is further configured to rejecting the I/O request and sending a queue full message; wherein the threshold value for the queue length is based on the processing rate of the I/O requests in the plurality of the I/O request queues.
