Small Computer Systems Interface (SCSI)
A standard that is used by computer manufacturers for attaching peripheral devices (such as tape
drives, hard disks, CD-ROM players, printers, and scanners) to computers (servers). Pronounced
"scuzzy". Variations of the SCSI interface provide for faster data transmission rates than standard
serial and parallel ports (up to 320 megabytes per second). The variations include
• Fast/Wide SCSI - Uses a 16-bit bus, and supports data rates of up to 20 MBps.
• SCSI-1 - Uses an 8-bit bus, and supports data rates of 4 MBps.
• SCSI-2 - Same as SCSI-1, but uses a 50-pin connector instead of a 25-pin connector, and supports
multiple devices.
• Ultra-SCSI - Uses an 8- or 16-bit bus, and supports data rates of 20 or 40 MBps.
• Ultra2 SCSI - Uses an 8- or 16-bit bus and supports data rates of 40 or 80 MBps.
• Ultra3 SCSI - Uses a 16-bit bus and supports data rates of 80 or 160 MBps.
• Ultra160 SCSI - Uses a 16-bit bus and supports data rates of 80 or 160 MBps.
• Ultra320 SCSI - Uses a 16-bit bus and supports data rates of 320 MBps.

See Storage Management Initiative Specification (SMI-S).
SMTP
Simple Mail Transfer Protocol. SMTP is a standard for email transmissions across the internet.
SNMP
Simple Network Management Protocol. SNMP is used by network management systems to monitor
network-attached devices for conditions that warrant administrative attention.
SNTP
Simple Network Time Protocol. Used to synchronize the clocks of network-attached devices.
SMW

Special feature
A feature that can be ordered to enhance the capability, storage capacity, or performance of a
product, but is not essential for its basic work.
SPI
Security Parameters Index.
SR
Service representative, see also CE.
SRAM
Static random access memory.
SS
Status store.
SSH
Secure Shell.
SSL (Secure Sockets Layer)
A set of cryptographic protocols for secure communications on the Internet for such things as web
browsing, email, Internet faxing, instant messaging, and other data transfer. SSL allows applications
to communicate across a network in a way that is designed to prevent eavesdropping, tampering, and
message forgery.
SSP
Serial SCSI Protocol.
