Certain aspects of the present disclosure are directed to a baseboard management controller (BMC) managing a computer system including N computer nodes. The BMC has: (a) a processor, (b) a physical network interface controller, (c) a first communication interface controller, (d) a memory having firmware stored. The firmware can: (a) initiate N virtual BMC stacks each managing at least one health or performance related aspect of a respective one of the N computer nodes, and (b) initiate N virtual network interface controllers each communicating with the physical network interface controller. Each of the virtual BMC stacks has a network interface configured to communicate with a respective virtual network interface controller, and each of the N virtual BMC stacks is configured to communicate with a network connected to the physical network interface controller through a virtual network interface controller.
