Installation Guide
PMB: Platform Management Board. Links the server
to the PAP unit.
PNP: Plug aNd Play. The ability to plug a device
into a computer and have the computer recognize
that the device is there.
POST: Power On Self Test. When power is turned
on, POST (Power-On Self-Test) is the diagnostic
testing sequence (or "starting program") that a
computer runs to determine if hardware is working
correctly.
PROM: Programmable Read-Only Memory.
PUID: PAM Universal/Unique IDentifier. PAM
software allocates a PUID (PAM Universal / Unique
Identifier) to each hardware / software object to
guarantee unambiguous identification.
The PUID for each hardware element can be
obtained by hovering the mouse over the
corresponding element in the PAM tree, e.g.:
PAM:/CELLSBLOCK_<NAME>/MODULE_x/QBB_y
/CPU_y.
Q
QBB: Quad Brick Board. The QBB is the heart of the
Bull NovaScale Server, housing 4 Itanium  2
processors and 16 DIMMs. Each QBB
communicates with other CSS Module components
via 2 high-speed bidirectional Scalability Port
Switches.
See SPS or FSS.
R
RAID: Redundant Array of Independent Disks. A
method of combining hard disk drives into one
logical storage unit for disk-fault tolerance.
RAM: Random Access Memory. A temporary
storage area for data and programs. This type of
memory must be periodically refreshed to maintain
valid data and is lost when the computer is
powered off. See NVRAM and SRAM.
RAS: Reliability, Availability, Serviceability.
Real-time clock: The Integrated Circuit in a
computer that maintains the time and date.
RFI: Radio Frequency Interference.
Ring: The CSS module interconnection ring
comprises the cables used to interconnect two, three
or four CSS modules.
RJ45: 8-contact regular jack.
RMC: Remote Maintenance Console.
ROM: Read-Only Memory. A type of memory device
that is used to store the system BIOS code. This
code cannot be altered and is not lost when the
computer is powered off. See BIOS, EPROM and
Flash EPROM.
RS-232 Port: An industry standard serial port. See
Serial Port.
RSF: Remote Service Facilities.
RTC: Real Time Clock.
S
[e-mail]: SAN Administration Tool.
SAL: System Abstraction Layer. Firmware that
abstract system implementation differences in IA-64
platform. See also PAL.
SAN: Storage Area Network. A high-speed
special-purpose network that interconnects different
kinds of data storage devices with associated data
servers on behalf of a larger network of users.
SAPIC: Streamlined Advanced Programmable
Interrupt Controller message.
SBE: Single Bit Error.
Scheme: Configuration file ensuring optimum use
and compatibility of the physical and logical
resources used to simultaneously run multiple
domains.
SCI: Scalable Coherent Interface.
SCSI: Small Computer System Interface. An input
and output bus that provides a standard interface
used to connect peripherals such as disks or tape
drives in a daisy chain.
SDR: Sensor Data Record.
SDRAM: Synchronous Dynamic Random Access
Memory. A type of DRAM that runs at faster clock
speeds than conventional memory. See DRAM.
SEL: System Event Log. A record of system
management events. The information stored includes
the name of the event, the date and time the event
occurred and event data. Event data may include
POST error codes that reflect hardware errors or
software conflicts within the system.
Serial Communication: Data sent sequentially, one
bit at a time.
Serial Port: Connector that allows the transfer of
data between the computer and a serial device.
See COM1 or COM 2.Shell is a Unix term for the
interactive user interface with an operating system.
