Abstract
A server chassis includes a plurality of microservers with each microserver including a Micro Baseboard Management Controller (μBMC) and at least one processor for controlling operation of the microserver. A BMC communication manager of the server chassis directly communicates with each μBMC of the plurality of micro-servers. A Chassis BMC (CBMC) connects to the BMC communication manager and communicates with the BMC communication manager via a plurality of communication protocols. The BMC communication manager translates at least one of the plurality of protocols to a different protocol for direct communication with each μBMC. According to one aspect, a μBMC is connected to an out-of-band port of a microserver for communicating with at least one processor of the microserver. According to another aspect, the BMC communication manager includes at least one CBMC connector for communicating with the CBMC, and a plurality of μBMC ports for communicating directly with a respective μBMC.
