SAS
Acronym for Secure Authentication Services or Serial-
attached SCSI. When referring to security protocols or
authentication, SAS is Secure Authentication Services.
When referring to computer peripheral devices that
employ a serial (one bit at a time) means of digital data
transfer over thin cables, SAS is Serial-attached SCSI.
SCA
Abbreviation for single connector attachment.
schema
A collection of class definitions that describes managed
objects in a particular environment. A schema is a
collection of class definitions used to represent
managed objects that are common to every
management environment, which is why CIM is called
the Common Information Model.
SCSI
Acronym for small computer system interface. An I/O
bus interface with faster data transmission rates than
standard ports. You can connect up to seven devices
(15 for some newer SCSI types) to one SCSI interface.
SEL
Acronym for system event log.
SDMS
Abbreviation for SCSI device management system.
sec
Abbreviation for second(s).
SEC
Abbreviation for single-edge contact.
secure port server
An application that makes Web pages available for
viewing by Web browsers using the HTTPS protocol.
See Web server.
serial port
An I/O port used most often to connect a modem to
your system. You can usually identify a serial port on
your system by its 9-pin connector.
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.
