4.4.3 Role of Integrated BMC in NM<br />
This section summarizes the Integrated BMC role in the NM feature implementation.<br />
4.4.3.1 External Communications Link<br />
The Integrated BMC provides the access point for remote commands from external<br />
management software and generates alerts to that software. The ME plays the role of an IPMI<br />
satellite controller that communicates to the Integrated BMC over a secondary IPMB. There are<br />
mechanisms to forward commands to ME and send response back to originator. Similarly<br />
events generated by ME to the Integrated BMC (via IPMB) have to be sent by the Integrated<br />
BMC to the external software over the LAN link. It is the responsibility of Integrated BMC to<br />
implement these mechanisms for communication with Node Manager (NM).<br />
4.4.3.1.1 Command Passing Via Integrated BMC<br />
External software wishing to communicate with the NM will send ‗bridged‘ IPMI commands to<br />
Integrated BMC. This will be in the form an IPMI packet encapsulated in another packet,<br />
following standard IPMI bridging as described in the IPMI 2.0 Specification. Integrated BMC<br />
forwards the encapsulated command it to NM engine on the ME and returns the response to<br />
the sender.<br />
Due to the fact that some of the NM commands have potential for performance limiting and<br />
system shut-down, the Integrated BMC firmware enforce an administrator privilege for any<br />
commands bridged to the ME.<br />
4.4.3.1.2 Alerting<br />
Alerts may be sent from the NM in the ME to the external software by one of two different<br />
methods depending on the nature of the alert.<br />
Alerts that signify fault conditions that should be recorded in the system SEL will be sent to the<br />
Integrated BMC by the ME using the IPMI Platform Event Message command. The Integrated<br />
BMC deposits such events into the SEL. The external software must configure the Integrated<br />
BMC‘s PEF and alerting features to then send that event out as an IPMI LAN alert, directed to<br />
the software application over the LAN link.<br />
