SAN — Storage area network. A configuration of computer and storage systems that
incorporate dedicated Fibre Channel connectivity between the computer systems
and storage. A SAN bypasses traditional network bottlenecks and supports direct
high-speed data transfer between the servers and storage devices. SAN storage may
consist of both hard-disk drive and tape storage devices that are connected through
switches and bridges to multiple servers.
SCSI — Small computer system interface. An I/O bus interface with faster data
transmission rates than standard ports.
SDRAM — Synchronous dynamic random-access memory.
sec — Second(s).
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.
service tag — A bar code label on the system used to identify it when you call Dell for
technical support.
simple disk volume — The volume of free space on a single dynamic, physical disk.
SMART — Self-Monitoring Analysis and Reporting Technology. Allows physical
disks to report errors and failures to the system BIOS and then display an error
message on the screen.
SMP — Symmetric multiprocessing. Used to describe a system that has two or more
processors connected via a high-bandwidth link and managed by an operating
system, where each processor has equal access to I/O devices.
SNMP — Simple Network Management Protocol. A standard interface that allows a
network manager to remotely monitor and manage workstations.
spanning — Spanning, or concatenating, disk volumes combines unallocated space
from multiple disks into one logical volume, allowing more efficient use of all the
space and all physical disk drive letters on a multiple-disk system.
striping — Disk striping writes data across three or more disks in an array, but only
uses a portion of the space on each disk. The amount of space used by a "stripe" is the
same on each disk used. A virtual disk may use several stripes on the same set of disks
in an array. See also guarding, mirroring, and RAID.
