Abstract
A method for processing a first input/output (I/O) request on a network attached storage (NAS) device that includes receiving the first I/O request from a source by the NAS device, placing the first I/O request in an I/O queue associated with the NAS device, wherein the first I/O request is placed in the I/O queue based on a priority of the first I/O request using a remote storage access protocol, and when the first I/O request is associated with the highest priority in the I/O queue, determining whether a bandwidth associated with the source of the first I/O request is exceeded, processing the first I/O request if the bandwidth associated with the source of the first I/O request is not exceeded, and placing the first I/O request in sleep mode if the bandwidth associated with the source of the first I/O request is exceeded.
