Abstract:
1. A method for processing a first input/output (I/O) request on a network attached storage (NAS) device, comprising: receiving the first I/O request from a first virtual machine 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: wherein the bandwidth associated with the first virtual machine is stored on the NAS device, wherein the bandwidth associated with the first virtual machine is updated when a bandwidth update message is transmitted to the NAS device from the first virtual machine, and wherein a second I/O request received from a second virtual machine is processed at a bandwidth associated with the second virtual machine when the first I/O request is placed in sleep mode.
