IPMI - technical background
Advantage
The IPMI specifications ensure the independence of functions for inventory,
logging, recovery and monitoring of a system by the system processor, BIOS or
operating system.
This means that a system can still be involved in platform management when it
is shut down and turned off.
IPMI and other management standards
IPMI is best used in conjunction with system management software running
under the relevant operating system. Integration of the IPMI functionality into the
management functionality offered by a management application and the
operating system results in a powerful platform management environment.
An overview of the relationship between IPMI and the management software
stack is shown by figure 2:
