peripheral devices, such as storage subsystems. The acronym is
pronounced “scuzzy.”
SCSI ID (Small Computer Systems Interface Address)
An address on a
SCSI BUS. Typically there are 16 addresses on a single channel
SCSI BUS.
Server
A powerful, centralized computer (or program) designed to
provide information to clients (smaller computers or programs)
upon request.
Serviceability
A RAS attribute that refers to a component that is
designed to accurately diagnose and report failures, as well as
minimize downtime in a storage solution. See also
RAS

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.

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
