Acronyms and Terminology
This section lists the definitions of acronyms and terms used in this specification. In some of the
definitions, the
IPMI Specification
is referred to.
Term Definition
BIOS Basic Input Output System. This is the boot firmware on a standard PC system (including servers). It also
provides some abstraction for system hardware.
BMC Baseboard Management Controller. This is the main component of the OPMA subsystem that provides IPMI
command processing, alerting, error logging, and so on in compliance with the IPMI specification.
BT IPMI’s Block Transfer command interface.
CLI Command Line Interface. This is a text-based interface to a BMC.
CMOS Commercial Metal Oxide Semiconductor. This term refers to a battery-backed storage element found on legacy
PC systems.
COTS Commercial Off The Shelf. This refers to items that are commonly available commercially, not custom.
DDC Display Data Channel. Provides plug-and-play data to whatever device the monitor is plugged into.
DDWG Digital Display Working Group—owns DVI specification.
DVI Digital Visual Interface. A set of buses for moving video data within a system. DVI-D digitally encodes the
video data and then puts it out onto a bus. DVI-A is simply the same analog video signals seen on a standard
VGA connector. DVI-I is the union of DVI-D and DVI-A signals to provide both methods of video information
transmission over a single cable and/or connector.
FRU Field Replaceable Unit. See the IPMI specification for details.
I
2
C Inter-Integrated Circuit bus. A simple two-wire bus often used to allow system processing elements to read low
cost sensor devices. An I
2
C device interfaces to the system via the I
2
C bus.
ICMB Intelligent Chassis Management Bus. An IPMI-defined bus for connecting management processors that exist in
separate physical chassis. See the IPMI specification for details.
IHV Independent Hardware Vendor. In this document the IHV is American Megatrends Inc.
IPMB Intelligent Platform Management Bus. An IPMI-defined bus for connecting management processors that exist
in a single physical chassis. See IPMI specification for details.
ISV Independent Software Vendor. Used in this specification to refer to the manufacturer of OPMA subsystem
board firmware, OS-level drivers and OS-level applications.
JTAG Joint Test Action Group
KCS IPMI’s Keyboard Controller Style command interface
KVMoIP Keyboard, Video and Mouse over Internet Protocol. Used for implementing remote video consoles on headless
(for example, no local keyboard mouse or display) servers.
LED Light Emitting Diode
LPC A reference to the low pin count bus specification. This is a common host system interface bus for BMCs.
LUN IPMI Logical Unit Number
mCard This is the generic name for an OPMA-compliant Management Card. It is a modular, connector based
management subsystem which contains the BMC and associated hardware resources. In this document,
“mCard”, “OPMA feature card” and MegaRAC M300V card are used interchangeably.
NIC Network Interface Chip (a/k/a Ethernet controller). Typically includes an Ethernet Media Access Controller
and may also include an integrated physical layer (PHY).
ODM Original Design Manufacturer. Used in this specification to refer to the developers of motherboards that are
used in a completed server system.
OEM Original Equipment Manufacturer. Used in this specification to refer to the server system manufacturer.
OOB Out Of Band. A platform hardware management communications channel that connects a remote console
directly to the BMC. This channel is working even when the managed platform is in a soft off state.
OPMA Open Platform Management Architecture. This acronym is used in several contexts as follows:
OPMA architecture—This is the overall description of the way OPMA subsystem cards connect to and interact
with the motherboard. It includes not only the OPMA connector and associated electrical specification, but
required firmware interfaces as well as other resources located on the motherboard that are required to support
the intended usage model. The OPMA architecture is described in this specification.
OPMA subsystem—An implementation of the OPMA architecture on the motherboard taken together with an
OPMA feature card.
OPMA feature card—This is a feature board that contains the majority of the management subsystem
hardware. The term “mCard” (management card) is often used for this in the interest of brevity.
OPMA connector—This is the connector into which an OPMA feature card (MegaRAC M300V card) is
plugged to provide a given system hardware management feature set.
