System Event Log Troubleshooting Guide for Intel ® S5500/S3420 series Server Boards Introduction
Revision 1.0 Intel order number G74211-001 3
The BMC allows access to SEL from in-band and out-of-band mechanisms. There are various
tools and utilities that can be used to access the SEL. There is the Intel
® SELViewer and
multiple open sourced IPMI tools.
1.2.3 Intel ® Intelligent Power Node Manager version 1.5
Intel ® Intelligent Power Node Manager version 1.5 (NM) is a platform resident technology that
enforces power and thermal policies for the platform. These policies are applied by exploiting
subsystem knobs (such as processor P and T states) that can be used to control power
consumption. Intel
® Intelligent Power Node Manager enables data center power and thermal
management by exposing an external interface to management software through which platform
policies can be specified. It also enables specific data center power management usage models
such as power limiting.
The configuration and control commands are used by the external management software or
BMC to configure and control the Intel
® Intelligent Power Node Manager feature. Since Platform
Services firmware does not have any external interface, external commands are first received
by the BMC over LAN and then relayed to the Platform Services firmware over IPMB channel.
The BMC acts as a relay and the transport conversion device for these commands. For
simplicity, the commands from the management console might be encapsulated in a generic
CONFIG packet format (config data length, config data blob) to the BMC so that the BMC
doesn
’t even have to even parse the actual configuration data.
BMC provides the access point for remote commands from external management SW and
generates alerts to them. Intel
® Intelligent Power Node Manager on Intel ® Manageability Engine
(Intel ® ME) is an IPMI satellite controller. A mechanism needs to exist to forward commands to
Intel ® ME and send response back to originator. Similarly events from Intel ® ME have to be sent
as alerts outside of BMC. It is the responsibility of BMC to implement these mechanisms for
communication with Intel
® Intelligent Power Node Manager.
