Glossary
ping: A basic Internet program that lets you verify
that a particular IP address exists and can accept
requests. The verb “to ping” means the act of using
the ping utility or command.
PIROM: P rocessor I nformation ROM . Processor
Information ROM (PIROM) contains information
about the specific processor in which it resides.
This information includes robust addressing
headers to allow for flexible programming and
forward compatibility, core and L2 cache electrical
specifications, processor part and S–spec
numbers, and a 64–bit processor number.
PMB: P latform M anagement B oard. Links the
server to the PAP unit.
PNP: P lug a N d P lay. The ability to plug a device
into a computer and have the computer recognize
that the device is there.
POST: P

T
est. 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: P rogrammable R ead- O nly M emory.
PUID: P AM U niversal/Unique ID entifier. 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: Q uad B rick B oard. 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: R

method of combining hard disk drives into one
logical storage unit for disk-fault tolerance.
RAM: R andom A ccess M emory. 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: R eliability, A vailability, S erviceability.
Real–time clock: The Integrated Circuit in a
computer that maintains the time and date.
RFI: R adio F requency I nterference.
RJ45: 8–contact regular jack.
RMC: R

ROM: R ead- O nly M emory. 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: R emote S ervice F acilities.

special–purpose network that interconnects
different kinds of data storage devices with
associated data servers on behalf of a larger
network of users.

and compatibility of the physical and logical
resources used to simultaneously run multiple
domains.

used to connect peripherals such as disks or tape
drives in a daisy chain.

SDRAM: S ynchronous D ynamic R andom A ccess
M emory. A type of DRAM that runs at faster clock
speeds than conventional memory. See DRAM.
SEL: S ystem E vent L og. 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.
