A part.
sel
Select.
Serial Attached SCSI (SAS)
A drive 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. It supports full-duplex signal transmission up to 3 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, which represents 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.
signature
A digital signature that is used in cryptography to identify one party to ensure authenticity.
slot blocker
A slot blocker is used to restrict/close off a data cell so a data cartridge cannot be inserted.
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.
SME
System Managed Encryption.
SMI-S
See Storage Management Initiative Specification (SMI-S).
SMTP
Simple Mail Transfer Protocol. SMTP is a standard for email transmissions across the internet.
SMW
Servo Manufacturer's Word.
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.
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.
SPI
Security Parameters Index.
SR
Service representative, see also CE.
SRAM
Static random access memory.
SS
Status store.
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.
ST
Store.
standard feature
The significant design elements of a product that are included as part of the fundamental product.
START
Start maintenance.
StartTLS
Secure LDAP communication that uses TLS.
Storage Management Initiative Specification (SMI-S)
A storage standard that is developed and maintained by the Storage Networking Industry Association (SNIA). It is also ratified as an ISO standard. The main
objective of SMI-S is to enable broad interoperable management of heterogeneous storage vendor systems.
subsystem
A secondary or subordinate system, capable of operating independently of, or asynchronously with, a controlling system.
SUPP
Support.
sync
Synchronous, synchronize. Occurring with a regular or predictable time relationship.
