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:
v Fast/Wide SCSI: Uses a 16-bit bus, and supports data rates of up to 20 MBps.
v SCSI-1: Uses an 8-bit bus, and supports data rates of 4 MBps.
v SCSI-2: Same as SCSI-1, but uses a 50-pin connector instead of a 25-pin connector, and supports
multiple devices.
v Ultra SCSI: Uses an 8- or 16-bit bus, and supports data rates of 20 or 40 MBps.
v Ultra2 SCSI: Uses an 8- or 16-bit bus and supports data rates of 40 or 80 MBps.
v Ultra3 SCSI: Uses a 16-bit bus and supports data rates of 80 or 160 MBps.
v Ultra160 SCSI: Uses a 16-bit bus and supports data rates of 80 or 160 MBps.
v Ultra320 SCSI: Uses a 16-bit bus and supports data rates of 320 MBps.
SKLM (IBM Security Key Lifecycle Manager)
IBM's EKM application that assists encrypting tape drives in generating, protecting, storing, and
maintaining encryption keys that encrypt information that is written to and decrypt information
that is read from tape media.
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.
Service representative, see also CE.
SR
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.
