The timing of this signal is not dependent upon the clock signal. Receipt of this signal by the controller indicates that the memory device is ready and the clock signal should be resumed so that a status of the command can be returned via the interface, or another command issued via the interface.

Abstract: Centralized quality-of-service (QoS) policies administration in a storage area network (SAN) is a problem without meaningful solutions. Current implementations require explicit administration of end points, which is error-prone and not scalable.

Accordingly, embodiments provide mechanisms to specify QoS parameters in a centralized manner to eliminate requiring a system administrator having to perform per-connection QoS provisioning.
