A system for scheduling storage accesses of multiple continuous media streams may include a plurality of media stream clients. Associated with each media stream client is one of a plurality of media stream managers. Each media stream manager maintains a ring of buffers that buffer media stream data between its associated media stream client and one or more storage systems. A deadline queue associated with one of the storage systems. Queues buffer requests from the media stream managers. Each buffer request includes a deadline by which the buffer request must be fulfilled by the corresponding storage system. Each media stream manager is configured so that once one of its buffers is consumed by the associated media stream client, it submits a buffer request and deadline for that buffer to the appropriate deadline queue. Buffer requests may be ordered in each deadline queue from earliest to latest deadline. Each media stream manager may be configured to provide a guaranteed maximum media stream rate to its associated media stream client.
