Port resource management within a multi-port memory system

An apparatus, comprising:

• a plurality of memory devices;
• a plurality of ports coupled with the plurality of memory devices, wherein:
• a first port of the plurality of ports is coupled with one or more host systems via at least one physical function;
• and
• the first port is configured to communicate with the one or more host systems via a host interface in accordance with a first communication protocol;
• and
• a system management interface coupled with a system management controller via a system management channel, wherein the system management controller is configured to allocate a plurality of resources within the apparatus to each port of the plurality of ports.

A memory system, comprising:

• one or more memory devices;
• and
• processing circuitry coupled with the one or more memory devices and configured to cause the memory system to:
• receive, at a memory system and via a system management channel coupled with the memory system, a first command that indicates a first port of a plurality of ports of the memory system is a trusted resource management port, wherein the trusted resource management port supports execution of one or more second commands, and wherein one or more second ports of the plurality of ports of the memory system restrict execution of the one or more second commands based at least in part on the first command;
• receive, at the trusted resource management port of the memory system, at least one second command, of the one or more second commands, that indicates an allocation configuration for allocating a plurality of resources of the memory system across the plurality of ports within the memory system;
• and
• allocate, to each port of the plurality of ports based at least in part on the at least one second command of the one or more second commands, a respective set of resources, of the plurality of resources, for execution of one or more subsequent second commands, of the one or more second commands, that are received at the plurality of ports.

A method, comprising:

• receiving, at a first port of a plurality of ports of a memory system and from a first host system of a plurality of host systems, one or more commands associated with an attestation of the first host system;
• receiving, at the first port from the first host system based at least in part on the attestation of the first host system, a first command that indicates a quantity of ports, of the plurality of ports of the memory system, to be activated;
• receiving, at the first port from the first host system based at least in part on the attestation of the first host system, at least one second command, of one or more second commands, to allocate a plurality of resources of the memory system to the quantity of ports, wherein each port of the quantity of ports is coupled with one or more respective host systems of the plurality of host systems;
• and
• allocating, to each port of the quantity of ports based at least in part on the one or more second commands, a respective set of resources of the plurality of resources.

A method, comprising:

• receiving, at a memory system and via a system management channel coupled with the memory system, a first command that indicates a first port of a plurality of ports of the memory system is a trusted resource management port, wherein the trusted resource management port supports execution of one or more second commands, and wherein one or more second ports of the plurality of ports of the memory system restrict execution of the one or more second commands based at least in part on the first command;
• receiving, at the trusted resource management port of the memory system, at least one second command, of the one or more second commands, that indicates an allocation configuration for allocating a plurality of resources of the memory system across the plurality of ports within the memory system;
• and
• allocating, to each port of the plurality of ports based at least in part on the at least one second command of the one or more second commands, a respective set of resources, of the plurality of resources, for execution of one or more subsequent second commands, of the one or more second commands, that are received at the plurality of ports.
