Abstract
Methods and systems for a storage environment are provided. A policy for an input/output (I/O) stream having a plurality of I/O requests for accessing storage at a storage device of the storage sub-system is translated into flow attributes so that the I/O stream can be assigned to one of a plurality of queues maintained for placing I/O requests based on varying priorities defined by set polices. When an I/O request for the associated policy is received by the storage sub-system; the storage sub-system determines a flow attribute associated with the I/O request and the policy; selects a queue for staging the I/O request, such that the selected queue is of either higher priority than what is indicated by the flow attribute or at least of a same priority as indicated by the flow attribute; and allocates storage sub-system resource for processing the received I/O request.
