    2. Agenda Introduction & Overview Architecture & Implementation What’s New for IPMI v1.0 Summary & Call to Action

    3. Agenda Introduction & Overview Architecture & Implementation What’s New for IPMI v1.0 Summary & Call to Action

    4. IPMI Initiative Intelligent Platform Management Interface IPMI v0.9 announced at Spring ‘98 Intel Developer Forum Made available for industry review Promoters: Intel, Hewlett-Packard, NEC, and Dell Owners of the specification, consolidated industry review input

    5. Initiative Status

    6. IPMI Initiative v1.0 is Ready to Go Adopters Sign royalty-free Adopter’s agreement for implementing the IPMI v1.0 specification Details on IPMI Web Site

    7. Initiative Status Adopter News! IPMI Adopters* - 9/16/98

    8. IPMI Origins Server Focus Keep it Running! RAS Features Focus Reliability Availability Serviceability Server Environment Remote administrator Expensive hardware High cost for downtime and repair

    9. Server Environment More extensive monitoring, control, and automatic recovery features Need for ‘Always Accessible’ management Complex system topologies Multiple internal boards, external peripheral chassis, modular ‘rack mount’ systems Multi-OS support

    10. The IPMI Challenge

    11. IPMI Strategy Specify the interface Intelligent Platform Management Interface

    12. IPMI Strategy Where it fits...

    13. The IPMI Solution

    14. IPMI Benefits System OEM Software Hardware

    15. IPMI Benefits System Provides the foundation for Intelligent Platform Management Autonomous access, monitoring, logging, and control features that function independently from the system processors, software, and OS Provides scalable support for entry to high-end systems Supports multi-chassis and modular configurations

    16. IPMI Benefits OEM Supports OEM differentiation Codes, events, and sensor types reserved for OEM use. Supports chassis feature integration without baseboard modifications Provides a common platform mgmt. configuration interface no need to touch BIOS FLASH no need for platform-specific utilities

    17. IPMI Benefits Software Speeds instrumentation software porting Makes platform management features ‘self-descriptive’ (Plug ‘N Play). Software automatically configures to platform management hardware Isolates mgmt. S/W from H/W changes Enables cross-platform software Standardized platform hardware interface enables mgmt. software and driver to work on multiple platforms. Can be used with any mgmt. S/W stack Designed for simple mapping to WMI/CIM Supports localization

    18. IPMI Benefits Hardware Preserves ability to innovate hardware Provides standardized interfaces for extending management features IPMB - for intra-chassis extensions and standardized Emergency Management Card Access ICMB - for inter-chassis extensions Facilitates ‘out-of-band’ secondary access Message based interface supports bridging to secondary management interfaces - NIC, RS-232, etc. Uses ‘off-the-shelf’ components

    19. Agenda Introduction & Overview Architecture & Implementation What’s New for IPMI v1.0 Summary & Call to Action

    20. IPMI Architecture Key Elements IPMI Messaging Command Sets Sensor Data Records Event Messages Baseboard Mgmt. Controller System Interface Non-volatile Storage Intelligent Platform Mgmt. Bus Intelligent Chassis Mgmt. Bus An example: HP TopTools An example: Intel Server Control

    21. IPMI Abstraction Messaging & Command Sets All IPMI operations are accomplished by sending messages to the management controllers Standardized commands defined in the IPMI specification All messages use a Request / Response Protocol Facilitates delivery over multiple transports: system interface, IPMB, ICMB, etc.

    22. IPMI Abstraction Messaging & Command Sets IPMI Commands grouped by functionality Supports modular firmware development Sensor and Event commands Application commands for controller specific functionality Chassis commands for chassis control & status Storage commands for non-volatile storage access Bridge commands Firmware Transfer commands OEM commands

    23. IPMI Abstraction SDRs Describe the population of sensors Location, ID, and access method Type (temp, voltage, processor, etc.), unit of measurement (volts, amps, bytes/sec, etc.), reading type (digital/discrete/analog) and threshold support Guide software in presenting sensor information normal reading ranges, sensor accuracy and tolerance sensor id string Identify the entity and/or FRU associated with each sensor Direct the sensor initialization process Initialization of Event Generation, Thresholds, Hysterisis, and/or Event Scanning

    24. IPMI Abstraction Event Messages Event Messages Standardized content - Event Messages Encapsulate Key Event Info: Sensor Type, Event Type, Event Transition, & Event Generator Combine with SDR info for richer event analysis Allow application to identify Entity and FRU associated with event Sensor short ID String etc.

    25. IPMI H/W Elements

    26. IPMI H/W Elements BMC Baseboard Management Controller Management Micro-controller provides the Intelligence for IPMI: Autonomous monitoring and logging Interface to IPMI Storage Receives and logs event messages System interface to IPMB / I2C System Watchdog Timer Optional power control functions. Plus OEM ‘value added’ mgmt. features

    27. IPMI H/W Elements System Interface Keyboard Controller Style Classic ‘8742’ Interface Available built-in to micros

    28. IPMI H/W Elements Non-volatile Storage System Event Log Centralized non-volatile storage for time-stamped Event Messages Compact 16-byte Event Records include provision for OEM event types and fields Message format tied to Sensor representation and access

    29. IPMI H/W Elements

    30. IPMI H/W Elements IPMB Standardized bus and protocol for extending management control, monitoring, and event delivery within the chassis. Provides integration point for chassis mgmt. features Offers standardized connection for ‘emergency management’ cards Multi-master I2C-based bus Simple request/response protocol Uses IPMI Command sets Supports non-IPMI devices

    31. IPMI H/W Elements Private Management Busses I2C-based, single master busses accessed via management controller Used primarily for IPMI FRU SEEPROMs Available for ‘value added’ I2C devices - outside IPMI context Shareable with ‘hidden’ I2C devices owned by the management controller Accessed via Master Write-Read I2C command Other I2C busses may be present - but these aren’t IPMI ‘Private Busses’ unless command access is provided

    32. IPMI Software Example: HP TopTools HP TopTools* Web-based management application for HP’s NetServers, Kayak workstations, and Vectra desktop clients* Data exposed to Java applications through a combination of DMI and SNMP NetServer agents have standardized on IPMI for hardware event log, sensors, and OS watchdog * Third-party marks and brands are the property of their respective owners. 1. TopTools is used to manage multiple device types via standard interfaces 2. NetServers have an SNMP-based event log agent, but the sensor & FRU data is from DMI component instrumentation1.

    33. IPMI Software Example: Intel Server Control Intel Server Control IPMI-based instrumentation software for Intel’s server board sets Automatically integrates additional chassis sensors: fans, temperatures, voltages, chassis intrusion, and power supplies Also uses non-IPMI interfaces, such as SM BIOS

    34. IPMI Specifications Tie it all together... IPMI - Intelligent Platform Management Interface BMC and satellite management controller functions Command set specifications Sensor Data Record and Event Log data formats IPMB - Intelligent Platform Management Bus Protocol Transport protocol, timing, electrical specifications, and connectors for the IPMB Plus supporting specifications...
