Installation Guide
SIO: Server I/O / Super I/O.
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.
SIOH: Server I/O Hub.
SMBIOS: System Management BIOS.
SM–BUS: System Management Bus.
SMIC: Server Management Interface Chip.
SMP: Symmetrical Multi Processor. The processing
of programs by multiple processors that share a
common operating system and memory.
SNC: Scalable Node Controller.
SNM: System Network Module.
SNMP: Simple Network Management Protocol.
The protocol governing network management and
the monitoring of network devices and their
functions.
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.
SPCR: Serial Port Console Redirection Table. This
table provides information about the configuration
and use of the serial port or non–legacy UART
interface.
SPS: Scalability Port Switch. Each CSS Module is
equipped with 2 Scalability Port Switches providing
high speed bi–directional links between system
components. See FSS.
SRAM: Static 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.
SSI: Server System Infrastructure.
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.
SVGA: Super Video Graphics Array.
T
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.
T&D: Tests and Diagnostics.
TCP: Transmission Control Protocol. 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: Transmission Control Protocol / Internet
Protocol. The basic communication language or
protocol of the Internet.
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 Universal Asynchronous Receiver
Transmitter. 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.
UML: Unified Modeling Language. A standard
notation for the modeling of real–world objects as a
first step in developing an object–oriented design
methodology.
UPS: Uninterruptible Power Supply. A device that
allows uninterrupted operation if the primary power
source is lost. It also provides protection from
power surges.
URL: Uniform / Universal Resource Locator. The
address of a file (resource) accessible on the
Internet.
