IPMI mapping to CIM

• Map IPMI domain to CIM domain

• No attempt to expose IPMI constructs in CIM

• CIM application is unaware of IPMI

• Self describing hardware interfaces make IPMI CIM provider hardware agnostic

CIM is the interface for management applicationsCIM is the interface for management applications

Summary

• IPMI is the foundation for powerful platform management

• CIM/WBEM is a powerful management model and interface to applications

• IPMI and CIM/WBEM together provide standards based comprehensive management solution for enterprise platforms


GlossaryBMC Baseboard Management Controller (an IPMI Controller on Baseboard)FRU Field Replaceable Unit. A field replaceable component such as a board, module,

fan, power supply, etc.ICMB Intelligent Chassis Management Bus. The ICMB provides a dedicated management

bus that enables delivering IPMI messages and alerts between multiple host and peripheral chassis.

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. IPMI defines a common, abstracted, and self-descriptive interface for platform management hardware that monitors server characteristics such as temperature, voltage, fans, power supplies, and chassis.

OOB Out-of-Band. System platform management access that does not involve going through the OS or other software running on the main processors of the managed system.

PEF Platform Event Filtering. A feature in IPMI that enables the BMC to generate a selectable action (e.g. power on/off, reset, send Alert, etc.) when a configurable event occurs on the management system.

SDR Sensor Data Record. SDRs provide the information that tells management software what sensors, events, management controllers, and FRU information is available from a given IPMI implementation.

SEL System Event Log. A non-volatile storage area and associated interfaces for storing system platform event information for later retrieval.
