US 2026/0129103 A1 · FACILITATING ENDPOINT REGISTRATION USING DISTRIBUTED SERVICES

Abstract

In a network fabric, such as a network having CLOS topology, non-volatile memory express (NVMe®) endpoints may be connected to one of centralized discovery controller (CDC) distributed services placed among multiple leaf switches, which may have resource constraints. Connection scale, delay, and jitter may occur if the CDC distributed services are not placed on leaf switches close to NVMe endpoints served by the CDC distributed services. System and method embodiments are disclosed for placement of CDC services on a switching network fabric close to endpoints that are served by the CDC services. The placement of CDC services may be implemented via push registration, pull registration, and/or manual DDC adding/registration such that the CDC services may be placed on desired leaf switches close to endpoints.

Dependent claims

A processor-implemented method for a network fabric comprising a plurality of spine switches and a plurality of leaf switches, the method comprising:

transmitting, using one or more distributed services deployed on a leaf switch from the plurality of leaf switches, one or more messages to one or more endpoints communicatively coupled to the leaf switch, the one or more messages comprising one or more local internet protocol (IP) addresses of the leaf switch;
using one or more listener services on the leaf switch to serve a connection request or requests received by the leaf switch;
receiving, at the leaf switch, a connection request from an endpoint from the one or more endpoint communicatively connected with the leaf switch;
and
causing, by the leaf switch, registration of the endpoint with a centralized service in response to the endpoint's connection request.

2 more elements

An information handling system comprising:

one or more processors;
and
a non-transitory information-handling-system-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:
transmitting, using one or more distributed services deployed on a leaf switch from a plurality of leaf switches of a network fabric comprising a plurality of spine switches and the plurality of leaf switches, one or more messages to one or more endpoints communicatively coupled to the leaf switch, the one or more messages comprising one or more local internet protocol (IP) addresses of the leaf switch;
using one or more listener services on the leaf switch to serve a connection request or requests received by the leaf switch;
receiving, at the leaf switch, a connection request from an endpoint from the one or more endpoint communicatively connected with the leaf switch;
and
causing, by the leaf switch, registration of the endpoint with a centralized service in response to the endpoint's connection request.

5 more elements

A non-transitory information-handling-system-readable medium or media comprising one or more sequences of instructions which, when executed by at least one processor, causes steps to be performed comprising:

transmitting, using one or more distributed services deployed on a leaf switch from a plurality of leaf switches of a network fabric comprising a plurality of spine switches and the plurality of leaf switches, one or more messages to one or more endpoints communicatively coupled to the leaf switch, the one or more messages comprising one or more local internet protocol (IP) addresses of the leaf switch;
using one or more listener services on the leaf switch to serve a connection request or requests received by the leaf switch;
receiving, at the leaf switch, a connection request from an endpoint from the one or more endpoint communicatively connected with the leaf switch;
and
causing, by the leaf switch, registration of the endpoint with a centralized service in response to the endpoint's connection request.
