- transmitting, by a first base management controller (BMC) associated with a first node, a first identifier associated with the first node onto a connection via a first transceiver of the first node;
transmitting, by a second BMC associated with a second node, a second identifier associated with the second node onto the connection via a second transceiver of the second node;
receiving, at the first BMC while the first node is in a pre-boot environment, first data including configuration information for the first node and the second identifier from the second BMC over the connection via the first transceiver;
receiving, at a resource manager, the first data and the second identifier from the first BMC, wherein said resource manager is associated with a server computer system;
receiving, at the second BMC while the second node is in a pre-boot environment, second data including configuration information for the second node and the first identifier from the first BMC over the connection via the second transceiver;
receiving, at said resource manager, the second data and the first identifier from the second BMC;
determining, by said resource manager, a classification of said first node and said second node and a compatibility of said first node with said second node based on said first data and said second data; and
generating, by said resource manager, a topology of said first node and said second node based on the first identifier and the second identifier,wherein transmitting, by the first BMC, the first identifier associated with the first node onto the connection via the first transceiver comprises;
pushing, by the first BMC, a first identifier associated with the first node onto a register space of the first transceiver;
initiating, by the first BMC, a command to the first transceiver to transmit the first identifier onto the connection; and
transmitting, by the first transceiver, the first identifier onto the connection responsive to initiation of the command.

Abstract
Various embodiments described herein provide for establishing connectivity of nodes by employing base management controllers associated with the nodes. For some embodiments, a first data is received at a resource manager from a first base management controller (BMC) associated with a first node, wherein the resource manager is associated with a server computer system. A second data is received at the resource manager from a second BMC associated with a second node. A classification of the first node and the second node are determined and a compatibility of the first node with the second node based on the first data and the second. A topology is generated, at the resource manager, of the first node and the second node.
