Glossary
The following list defines or identifies technical terms, abbreviations, and acronyms
used in your system documents.
authentication
The Server Administrator remote access controller has two methods of
authenticating user access:
RAC authentication and local operating system authentication. RAC authentication
is always enabled. Administrators can set up specific user accounts and passwords
that allow access to the RAC.
Operating systems also require administrators to define different levels of users
and user accounts; each user level has different privileges. Local operating system
authentication on the RAC is an option for administrators who do not want to
define one set of privileges for users in the operating system and a separate set of
users and accounts for the RAC. If you enable local operating system
authentication for the RAC, you enable any user with Administrator status on
the operating system to log in to the RAC.
baud rate
A measurement of data transmission speed. For example, modems are designed
to transmit data at one or more specified baud rate(s) through the COM (serial)
port of a system.
BMC
Abbreviation for baseboard management controller, which is a controller that
provides the intelligence in the IPMI structure.
BTU
Abbreviation for British thermal unit.
CA
Abbreviation for certification authority.
capability
Refers to the actions that an object can perform, or actions that can be taken on
a managed object. For example, if a card is hot-pluggable, it is capable of being
replaced while the system power is on.
