Glossary
SAS
Short for Serial Attached SCSI, SAS is an evolution of parallel SCSI into a point-
to-point serial peripheral interface in which controllers are linked directly to
disk drives.
SATA
Abbreviation for Serial Advanced Technology Attachment, it refers to a newer
interface standard for PC hard-disk drives. Each SATA port communicates
through a small cable, to a single hard drive.
schema
A collection of class definitions that describes managed objects in a particular
environment. A CIM 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.
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.
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.
