Shell: The Shell is the layer of programming that
understands and executes the commands a user
enters. As the outer layer of an operating system,
the Shell can be contrasted with the kernel, the
inmost layer or core of services of an operating
system. See EFI Shell.

ub. This component provides a
connection point between various I/O bridge
components and the Intel 870 chipset.
Sideband: This part of the CSS module
inter-connection ring comprises logistic cables
(errors, commands, resets). See Ring.

system bus interface and memory controller for the
Intel870 chipset. The SNC supports both the
Itanium2 processors, DDR SDRAM main memory, a
Firmware Hub Interface to support multiple
Firmware hubs, and two scalability ports for access
to I/O and coherent memory on other nodes,
through the FSS.

Socket: C entral P rocessing U nit mutlticore interface.
Each socket can house 1 or 2 processor cores. See
Microprocessor and CPU.
Source: Each message refers to a source (the
resource that generated the message) and a target
(the component referred to in the message). This
feature can be allows messages to be filtered
according to one or more
Source string(s) and is
particularly useful for debugging and
troubleshooting. See Target.
SPD: S erial P resence D etect. DIMM PROM.
SPS: S calability P ort S witch. Each CSS Module is
equipped with 2 Scalability Port Switches providing
high speed bi-directional links between system
components. See FSS.
SRAM: S tatic RAM . A temporary storage area for
data and programs. This type of memory does not
need to be refreshed, but is lost when the system is
powered off. See NVRAM and RAM.

Status Pane: One of the three areas of the PAM
web page. Provides quick access to CSS Module
availability status, server functional status, and
pending event message information. See also
Control pane and PAM Tree pane.

Target: Each message refers to a target (the
component referred to in the message), identified
by its PUID, and a source (the component that
generated the message).This feature allows
messages to be filtered according to one or more
Target
string(s) and is particularly useful for
debugging and troubleshooting. See Source and
PUID.
Task:
Each message refers to a target (the
component referred to in the message), identified
by its PUID, and a source (the component that
generated the message).This feature allows
messages to be filtered according to one or more
Target string(s) and is particularly useful for
debugging and troubleshooting. See Source and
PUID.
TCP: T ransmission C ontrol P rotocol. A set of rules
(protocol) used along with the Internet Protocol (IP)
to send data in the form of message units between
computers over the Internet.
TCP/IP: T ransmission C ontrol P rotocol / I nternet
P rotocol. The basic communication language or
protocol of the Internet.
T&D: T
ests and
D
iagnostics.
Thresholding: A PAM Event filter criterion.
Thresholding is defined on a Count / Time basis
aimed at routing significant messages only. Identical
messages are counted and when the number of
messages indicated in the
Count field is reached
within the period of time indicated in the Time field,
this message is selected for routing.
U
UART: a U niversal A synchronous R eceiver
T ransmitter. The microchip with programming that
controls a computer interface to its attached serial
devices.
ULTRA SCSI:
An enhanced standard 16-bit SCSI
interface providing synchronous data transfers of up
to 20 MHz, with a transfer speed of 40M bytes per
second. It is also called Fast-20 SCSI.
