Abstract
A fault tolerant, multi-protocol shelf management controller architecture that is extensible provides an intelligent platform management interface that is version indifferent as well as programmable and reconfigurable. The shelf management controller is arranged in a dual redundant configuration in a client-server mode and has a message driven configuration with the messages conforming to the Intelligent Platform Management Interface (IPMI) specification as extended by PICMG 3.0. In one embodiment, each shelf management controller includes at least one bit stream processor comprising sequenced stage machines implementing one or more finite state machines associated with one or more devices that are under control of the shelf management controller. The finite state machines could be hardware or software based. The shelf management controller is also modeled as a layered architecture that includes an IPMI API layer. The IPMI API layer enables the shelf manager to interface with legacy and future IPMI specifications.
