102 Glossary
settings
Settings are conditions of a manageable object help to
determine what happens when a certain value is
detected in a component. For example, a user can set
the upper critical threshold of a temperature probe to
75 degrees Celsius. If the probe reaches that
temperature, the setting results in an alert being sent
to the management system so that user intervention
can be taken. Some settings, when reached, can trigger
a system shutdown or other response that can prevent
damage to the system.
server module
A modular system component that functions as an
individual system. To function as a system, a server
module is inserted into a chassis which includes power
supplies, fans, a system management module, and at
least one network switch module. The power supplies,
fans, system management module, and network switch
module are shared resources of the server modules in
the chassis. See modular system.
service tag number
A bar code label that identifies each system in the
event that you need to call for customer or
technical support.
SGRAM
Acronym for synchronous graphics RAM.
shadowing
A computer's system and video BIOS code is usually
stored on ROM chips. Shadowing refers to the
performance-enhancement technique that copies
BIOS code to faster RAM chips in the upper memory
area (above 640 KB) during the boot routine.
SIMD
Abbreviation for Single Instruction Multiple Data.
SIMM
Acronym for single in-line memory module. A small
circuit board containing DRAM chips that connects to
the system board.
SIP
Acronym for single in-line package, which is a type of
housing for electronic components in which the
connecting pins protrude from one side. A SIP is also
called a Single In-line Pin Package (SIPP).
SKU
Acronym for stock keeping unit.
SMART
Acronym for Self-Monitoring Analysis and Reporting
Technology. A technology that allows hard drives to
report errors and failures to the system BIOS, which
then displays an error message on the screen. To take
advantage of this technology, you must have a
SMART-compliant hard drive and the proper support
in the system BIOS.
SMBIOS
Acronym for system management BIOS.
SMD
Abbreviation for surface mount device.
SMTP
Abbreviation for Simple Mail Transfer Protocol.
SNMP
Abbreviation for Simple Network Management
Protocol. SNMP, a popular network control and
monitoring protocol, is part of the original TCP/IP
protocol suite. SNMP provides the format in which
vital information about different network devices, such
as network servers or routers, can be sent to a
management application.
SODIMM
Acronym for small outline-DIMM. A DIMM module
with a thinner profile due to the use of TSOP chip
packages. SODIMMs are commonly used in
portable computers.
