A board management controller (BMC) is a specialized microcontroller that provides the intelligence and control for a computer system. It is responsible for monitoring the system’s health, managing system resources, and providing a platform for remote management. BMCs are typically found in servers, workstations, and other high-end computing systems.
The BMC is responsible for monitoring the system’s health, including temperature, fan speed, and voltage. It can also detect and report system errors, such as memory or processor failures. The BMC can also be used to manage system resources, such as power, cooling, and storage. It can also be used to provide a platform for remote management, allowing administrators to access the system remotely and perform tasks such as system updates, configuration changes, and system diagnostics.
The BMC is typically connected to the system’s baseboard management controller (BMC) via a serial or Ethernet connection. The BMC is typically powered by a separate power source, such as a battery or an external power supply. The BMC is typically programmed using a specialized language, such as IPMI or Redfish.
BMCs are an important component of any high-end computing system. They provide the intelligence and control necessary to ensure the system’s health and performance. They also provide a platform for remote management, allowing administrators to access the system remotely and perform tasks such as system updates, configuration changes, and system diagnostics.
