Abstract: A system and method for satisfying Quality of Service (QoS) attributes for a stream using a storage device with multi-stream capability is described. The storage device may include memory to store data. A host interface may receive requests, some of which may be associated with a stream. A host interface layer may schedule the requests in a manner that may satisfy the

Abstract: A distributed storage system node (125, 130, 135) is disclosed. The distributed storage system node (125, 130, 135) may include at least one storage device (140, 145, 150, 155, 160, 165, 225, 230), which may act as the primary replica (2315) for data subject to an Input/Output (I/O) request (905). A cost analyzer (2310) may calculate a local estimated time required (3305) to complete the I/O request (905) at the primary replica, and a remote estimated time required (3710) to complete the I/O request (905) at a secondary replica (2320, 2325) of the data. An I/O redirector (215) may direct the I/O request (905) to either the primary replica (2315) or the secondary replica (2320, 2325) based on the local estimated time required (3305) and the one remote estimated time required (3710).

Abstract: A system and method for satisfying Quality of Service (QoS) attributes (620) for a stream (405, 410) using a storage device (120) with multi-stream capability is described. The storage device (120) may include memory (510, 515, 520) to store data. A host interface (525) may receive requests (345, 350, 415, 420, 425, 430, 435, 440), some of which may be associated with a stream (405, 410). A host interface layer (545) may schedule the requests (345, 350, 415, 420, 425, 430, 435, 440) in a manner that may satisfy the QoS attribute (620) for the stream (405, 410).
