Abstract:
A round robin system with interleaved weighted and priority arbiters to serve on-demand bandwidth of a storage system are provided. In one embodiment, a host assigns a priority and weight to each of a plurality of memory commands. The memory commands are sent to the storage system in a priority round-robin manner, in which memory commands assigned to a relatively-higher priority level are sent to the storage system before memory commands assigned to a relatively-lower priority level. Further, memory commands assigned to a given priority level are sent to the storage system in a weighted round-robin manner in accordance with their assigned weight. Other embodiments are provided.
