Glossary
Partition
System equipped with the functions of a
processing unit. Each partition contains
software resources such as an OS and
applications as well as hardware resources such
as SBs and IO_Units.
PCI_Box
Device used for PCI slot expansion
PCI Hot Plug
Technology that enables PCI cards to be
mounted and removed while the system is
operating
PCI (Peripheral Component
Interconnect)
Bus architecture established by PCI SIG for
connecting PC components
PCIU (PCI Unit)
Unit that is mounted in a PCI_Box
Platform
OS type or environment that is the basis for
operation of application software
POST (Power-On Self Test)
Hardware test that is automatically run when
the computer is powered on
Private LAN
LAN used for internal control, under which
firmware programs installed on hardware
components communicate with one another.
MMB firmware, GSWB firmware, and BMC
firmware installed on I/O_Units can use a
private LAN for communication with one
another. OSs and applications cannot use a
private LAN.
GL-4
PSA (PRIMEQUEST Server Agent)
Software that performs hardware error
monitoring and configuration management
over PRIMEQUEST partitions
PSU (Power Supply Unit)
Component that converts AC voltage to DC
voltage as a DC power supply
RAID (Redundant Array of
Independent Disks)
Technology that increases reliability and
processing speeds by using multiple hard disks
as a single disk
