The Baseboard Management Controller (BMC), often identified by the model number (e.g., "3307"), is a specialized microcontroller embedded in many server and workstation motherboards. The BMC provides remote management capabilities, including power control, hardware monitoring, and system health monitoring, independent of the main processor and operating system. This controller is part of technologies like IPMI (Intelligent Platform Management Interface), which is used to manage and monitor the health of a server even when it is powered off or unresponsive.
The Baseboard Management Controller (3307) Windows driver is a software package that allows your Windows operating system to interface with the BMC hardware and enable features such as remote management, hardware health status reporting, and other functions specific to the server or workstation system.
