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.

Specialist web interface
A platform-independent, web-based
interface that allows a user to configure
and monitor the TS3500 Tape Library
from a remote location.
speed matching
The ability of the Ultrium 2 and newer
Ultrium tape drives to adjust their native
data rate as closely as possible to the net
host data rate (after data compressibility
has been factored out).
SSL See Secure Sockets Layer .
stand-alone
Pertaining to operation that is
independent of any other device,
program, or system.
Statistical Analysis and Reporting System
(SARS)
Firmware that is built into the 3592 tape
drives and the Ultrium tape drives and
which is used by the drive during
problem determination to identify which
single-character display code,
ASC/ASCQ, and/or TapeAlert to report.
StE See storage element .
Storage Area Network (SAN)
A high-speed subnetwork of shared
storage devices. A SAN's architecture
makes all storage devices available to all
servers on a LAN or WAN. As more
storage devices are added to a SAN, they
too will be accessible from any server in
the larger network. Because stored data
does not reside directly on any of a
network's servers, server power is used
for business applications, and network
capacity is released to the end user.
storage element (StE)
In SCSI terms, a cartridge storage slot.
storage environment
The temperature, relative humidity rate,
and wet bulb temperature of the
environment in which the TS3500 Tape
Library is nonoperational and being
stored for future use.
Storage Management Initiative - Specification
(SMI-S)
A design specification of the Storage
Management Initiative (SMI) that was
launched by the Storage Networking
Industry Association (SNIA). The SMI-S
specifies a secure and reliable interface
that allows storage management systems
to identify, classify, monitor, and control
physical and logical resources in a Storage
Area Network (SAN).
Storage Management Initiative - Specification
(SMI-S) Agent for Tape
Software that is used by management
software to communicate with storage
devices in a SAN environment. The SMI-S
Agent for Tape communicates by using
the Web-Based Enterprise Management
(WBEM) protocol, which allows
management software to communicate
with the TS3500 Tape Library.
sustained data transfer rate
Between the server and the tape drive,
the average transfer rate of data across
the SCSI interface to and from the tape
drive during a transition from one end of
the tape to the other end.
switch A network infrastructure component to
which multiple nodes attach. Unlike hubs,
switches typically have the ability to
switch node connections from one to
another. A typical switch can facilitate
several simultaneous bandwidth
transmissions between different pairs of
nodes.
system console
A service tool that monitors the tape
library and other components for early
detection of unusual conditions and for
error information that the components
