IPMI v2.0 Technology Update
v2.0 Addenda & Errata RMCP+ Clarifications – packet format and RAKP protocol operation – corrected inconsistencies in authentication, confidentiality, and integrity algorithm descriptions
Firmware Firewall – added ability to report and configure OEM-defined commands
SSIF – SMBus System Interface legitimized for use with IPMI v1.5 implementations
Platform Event Filtering – added option for filtering on OEM events 10
IPMI v2.0 Technology Update
v2.0 Addenda & Errata “Alert Immediate” command – new option to allow event data to be incorporated in alert
Extended Sensor types: – System Boot / Restart Initiated – formerly “System Boot” - extended for reporting OS startup events
– OS Stop / Shutdown – formerly “Critical Stop” - extended for reporting graceful and watchdog-triggered OS shutdown -related events
– Management Subsystem Health – extended to report failures of sensors and FRU devices
11
IPMI v2.0 Technology Update
v2.0 Addenda & Errata New Units types – grams, fatal error
New Entity types: – system Real Time Clock (RTC)

IPMI v2.0 in Action
Payloads in Action
IPMI v2.0 Payloads enable multiple types of traffic to be carried over a single IPMI session – payloads can also be launched to a separate session
Standard and OEM Payload Types supported – Standard payload types: Support Session Setup, IPMI Messages, “Serial Over LAN”
– OEM payload types: Enable value-added features on IPMI session infrastructure
Payloads leverage IPMI Session infrastructure – User Authentication, Configuration, Protocols
Session Payloads Reduce Development Effort for Value-added Features 14

IPMI v2.0 in Action
IPMI and WMX* Proof-of-Concept – Microsoft and Intel demonstrate local and remote management using IPMI and WMX technology at WinHEC 2004
* Other names and brands may be claimed as the property of others 17
IPMI v2.0 in Action
What is WMX? A SOAP-based protocol, originated by Microsoft*, that defines a small number of fixed operations for system management access – Includes functions for enumerating the information and functions that can be accessed on a given platform
Based on Web-Services standards and technologies Uses URIs and XML data for access to management information and control functions – Conceptually and technologically aligned with Web Services – based interfaces being looked at by DMTF*

IPMI continues to be
– Infrastructure for implementation under DMTF interfaces – ‘Inside-the-Box’ interface, e.g. – Between BMC and system components – Between CMM and blades – Alternative OOB interface when Manageability Access Point is a SW Proxy – For ‘low-end’ implementations – For migration and support of installed base
