Abstract
One embodiment facilitates measurement of a performance of a storage device. During operation, the system determines a normalized cost for an I/O request, wherein the normalized cost is independent of an access pattern and a type of the I/O request, wherein the normalized cost is indicated by a first number of virtual I/O operations consumed by the I/O request, and wherein a virtual I/O operation is used as a logical unit of cost associated with physical I/O operations. The system identifies a performance metric for the storage device by calculating a second number of virtual I/O operations per second which can be executed by the storage device. The system allocates incoming I/O requests to the storage device based on the performance metric, e.g., to satisfy a Quality of Service requirement, thereby causing an enhanced measurement of the performance of the storage device.
