    摘要: A method for executing input/output (I/O) operations based on priority involves receiving a first I/O request for a unit of data, receiving a second I/O request for the same unit of data, determining a priority of the first I/O request and a priority of the second I/O request, and executing the first I/O request based on priority, where the first I/O request is executed based on the higher of the priority of the first I/O request and the priority of the second I/O request.

    摘要: A method for storing data, including receiving a request to store data in a storage pool, determining a quantized deadline for the request, placing the request in an Input/Output (I/O) queue using the quantized deadline, and issuing the request to the storage pool using the I/O queue.
