Baseboard Management Controller (BMC), also called as Service processor, resides on each blade for OS independent/pre-OS management. The BMC's focus is to monitor/manage a single blade in the UCS chassis. The UCS manager talks to the BMC and configures the blade. Its primary function is to provide out-of-band remote management capabilities for the system, meaning it allows administrators to monitor and manage servers. The Baseboard Management Controller (BMC) is a remote management device that enables you to access, monitor, and troubleshoot a node remotely. The key capabilities of the BMC include the following: Remotely diagnose, shut down, power-cycle, or reboot the node, regardless of the state of the node. A baseboard management controller, or BMC, is a small computer that sits on virtually every server motherboard. Other components such as higher-end switches, JBODs, JBOFs, and other devices now include BMCs as well.
