Abstract
The present disclosure describes apparatuses and techniques for implementing a Quality of Service-enabled (QoS-enabled) storage controller. In various aspects, a QoS manager of a storage controller or hardware accelerator can implement credit-based policies for servicing inbound input/output (I/O) commands of a host. In some cases, the QoS manager implements a queue-based credit policy or function-based credit policy to manage traffic across host submission queues or functions of the storage controller. In a data phase of command processing, the QoS manager may segment or chunk an I/O command based on a size threshold to provide I/O command segments of similar amounts of respective data for processing by a direct memory access (DMA) engine of the storage controller. By so doing, the QoS manager can manage entity-based data traffic such that no entity within or associated with the storage controller exceeds its allocated bandwidth.
