Scalable quality of service (QoS) for a nonvolatile memory express™ environment

An information handling system comprising:

• one or more processors;
• and
• a non-transitory computer-readable medium or media comprising one or more sets of instructions which, when executed by at least one of the one or more processors, causes steps to be performed comprising:
• at a discovery controller (DC) in a network, which comprises entities comprising one or more hosts and one or more subsystems, receiving one or more zone configurations representing a set of access control rules that determine which of the one or more hosts are authorized to connect to which of the one or more subsystems and indicates one or more QoS parameters to use when forming these connections;
• and
• responsive to an entity in the network issuing a request to the DC to discover those entities that the entity is authorized to establish a connection with according to a zone configuration from the one or more zone configurations, providing to the entity:
• a list of one or more entities according to the zone configuration;
• and
• for at least one of the entities on the list, an indication of a QoS parameter to use for data traffic when corresponding with the at least one of the entities.

A computer-implemented method comprising:

• issuing, from an entity of a network, which network comprises entities comprising one or more hosts and one or more subsystems, to a discovery controller (DC), which maintains one or more zone configurations representing a set of access control rules that determine which of the one or more hosts are authorized to connect to which of the one or more subsystems and indicates one or more QoS parameters to use when forming these connections, a request to discover those entities that the entity is authorized to establish a connection with according to a zone configuration from one or more zone configurations;
• receiving a response from the DC comprising:
• a list of one or more entities according to the zone configuration;
• and
• for at least one of the entities on the list, an indication of a QoS parameter to use for data traffic when corresponding with the at least one of the entities;
• and
• using the QoS parameter to specify a QoS level for data traffic when corresponding with the at least one of the entities.
