BMC
IPMI
IRQ
SMBIOS
Polling mode

3. BMC-Baseboard Management Controller
The intelligence in the
IPMI architecture.
Manages the
interface between
system management
software and
platform hardware.

4. IPMI-Intelligent Platform
Management Interface
A set of computer interface specifications for an
autonomous computer subsystem
Provides management and monitoring
capabilities independently of the host system's
CPU, firmware (BIOS or UEFI) and operating
system.
IPMI functions can work in any of three scenarios:
before an OS has booted (allowing, for
example, the remote monitoring or changing
of BIOS settings)
when the system is powered down
after OS or system failure – the key
characteristic of IPMI compared with in-band
system management such as by remote
login to the operating system using SSH

5. IRQ-Interrupt ReQuest
A hardware signal
sent to the processor
that temporarily
stops a running
program and allows
a special program,
an interrupt handler,
to run instead.

6. SMBIOS-System
Management BIOS
Defines data structures
(and access methods) that
can be used to read
information stored in the
BIOS of a computer.

7. Polling Mode
Actively sampling the status of an
external device by a client
program as a synchronous activity.
Polling is sometimes used
synonymously with busy-wait
polling (busy waiting). In this
situation, when an I/O operation is
required, the computer does
nothing other than check the
status of the I/O device until it is
ready, at which point the device is
accessed.
