What is Baseboard management controller?

Definition 8.9 Networks, Hardware and Trading Infrastructure · Chapter 8 — Servers

A baseboard management controller (BMC) is a small independent computer on the server’s motherboard, with its own network port, that lets an operator power the server on and off, read its sensors and logs, update its firmware and use its console remotely, whatever the state of the main processor and operating system.

A two-socket trading server. The network card sits on socket 0’s bus and the hot threads run on socket 0’s cores with socket 0’s memory (One Quant Book 13, chapter 4); socket 1 takes everything else. The baseboard management controller watches and controls the machine from its own port on the management network.
