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.

Abstract: Systems and methods utilize discovery log entry identifiers (DLEIDs) to identify individual discovery log page entries (DLPEs) in a discovery log page, for example, to allow a name server to manipulate DLPEs and perform specific operations, including zoning operations. Thus, DLEIDs advantageously reduce data flow and repetitive full discovery log page requests and responses and associated processing times; especially, in scenarios where changes to data are minimal. Further, a DLEID-based get log page command may be used to perform push and pull registrations, e.g., to query a specific set of end devices. Advantageously, this reduces messages size and, thus, the number of messages that need to be exchanged, e.g., during an addition or deletion of end devices, especially in larger environments.
