IP Internet Protocol.
IPMB Intelligent Platform Management Bus. Name for the architecture, protocol, and implementation of
a special bus that interconnects the baseboard and chassis electronics and provides a
communications media for system platform management information.
IPMI Intelligent Platform Management Interface. An industry standard that defines standardized,
abstracted interfaces to platform management hardware.
