to peripheral devices, such as storage subsystems. The acronym
is pronounced “scuzzy.”
Server A powerful, centralized computer (or program) designed to
provide information to clients (smaller computers or programs)
upon request.
Setup wizard A tool for initially configuring the library. It appears the
first time the user starts the library. However, it can be used to
modify configurable items anytime after the initial
configuration.
Sled The hardware that houses tape drives in the library.
SMI-S (Storage Management Initiative Specification) An industry
standard SMI-S application programming interface (API)
developed by SNIA that facilitates the management of multi-
vendor devices in a storage area networks (SANs) environment.
Snapshot A rapid, point-in-time image of a volume created initially on
the same disk as the original by duplicating metadata rather
than copying the full data set. Snapshots are often used to
protect against data corruption (viruses, etc.) or to create test or
pre-production environments. Snapshots are also often used as
a first step for creating non-disruptive point-in-time backups,
and for copying datasets to a second disk to create a full
duplicate copy of the volume. Snapshots are created on disk,
and in the same format as the original data. Snapshots are also
referred to as point-in-time copies and as shadow copies.
SNMP (Simple Network Management Protocol)
The protocol
governing network management and the monitoring of
network devices and their functions. Similar in function to SAM,
except SNMP governs LAN, whereas SAM governs SAN.
SSL (Secure Sockets Layer) A protocol that provides encrypted
communications on the Internet. SSL is layered beneath
application protocols such as HTTP, SMTP, Telnet, FTP, Gopher,
and NNTP and is layered above the connection protocol TCP/IP.
Storage device
An appliance containing data that can be accessed,
added to, changed, or deleted by the user. The storage media
types include tapes and optical disks. A storage device can be a
single disk drive, or constitute thousands of tapes in a large
tape library.
Storage slot
The physical home where a data cartridge resides.
