segment. A part.

sel. Select.

Serial Attached SCSI (SAS). A drive sled with a SAS interface can be linked directly to controllers. SAS is a performance improvement over traditional SCSI because SAS enables multiple devices (up to 128) of different sizes and types to be connected simultaneously with thinner and longer cables; its full-duplex signal transmission supports 3.0 Gb/s. In addition, SAS drives can be hot-plugged.

serialize. To change from parallel-by-byte to serial-by-bit.

serializer. A device that converts a space distribution of simultaneous states representing data into a corresponding time sequence of states.

servo, servos. An adjective for use in qualifying some part or aspect of a servomechanism.

servomechanism. A feedback control system in which at least one of the system signals represents mechanical motion.

Simple Network Management Protocol. SNMP, a standard TCP/IP protocol to send alerts about conditions (such as need for operator intervention) over a TCP/IP LAN network to an SNMP monitoring station.

Slot Blocker. A slot blocker is used to restrict/close off a data cell so a data cartridge cannot be placed there. This blocker can easily be removed.

Small Computer Systems Interface (SCSI). A standard 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 160 megabytes per second). The variations include:

vFast/Wide SCSI: Uses a 16-bit bus, and supports data rates of up to 20 MBps.

vSCSI-1: Uses an 8-bit bus, and supports data rates of 4 MBps.

vSCSI-2: Same as SCSI-1, but uses a 50-pin connector instead of a 25-pin connector, and supports multiple devices.

vUltra SCSI: Uses an 8- or 16-bit bus, and supports data rates of 20 or 40 MBps.

vUltra2 SCSI: Uses an 8- or 16-bit bus and supports data rates of 40 or 80 MBps.

vUltra3 SCSI: Uses a 16-bit bus and supports data rates of 80 or 160 MBps.

vUltra160 SCSI: Uses a 16-bit bus and supports data rates of 80 or 160 MBps.

SNMP. Simple Network Management Protocol, a standard TCP/IP protocol to send alerts about conditions (such as need for operator intervention) over a TCP/IP LAN network to an SNMP monitoring station.

SNS. Sense.

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.

SRAM. Static random access memory.

SS.Status store.

SSL. SSL, or Secure Socket Layer is a cryptographic protocol that provide secure communications on the Internet for such things as web browsing, EKM communication, Internet faxing, instant messaging and other data transfers. This protocol allows applications to communicate across a network in a way designed to prevent eavesdropping, tampering, and message forgery.

ST. Store.

standard feature. The significant design elements of a product that are included as part of the fundamental product.

START. Start maintenance.

subsystem. A secondary or subordinate system, usually capable of operating independently of, or asynchronously with, a controlling system.

SUPP. Support.

sync. Synchronous, synchronize. Occurring with a regular or predictable time relationship.

T

tachometer, tach. A device that emits pulses that are used to measure/check speed or distance.

tape cartridge. A container holding magnetic tape that can be processed without separating it from the container.

tape void. An area in the tape in which no signal can be detected.

TCP/IP. Transmission Control Protocol/Internet Protocol.

TCU. Tape control unit.
