speed matching
The ability of the LTO 2 and later LTO
tape drives to adjust their native data rate
as closely as possible to the net host data
rate (after data compressibility is 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 LTO tape drives and 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 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 TS4500 tape
library is non-operational and being
stored for future use.
Storage Management Initiative - Specification
(SMI-S)
A design specification of the Storage
Management Initiative (SMI) that was
started 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 TS4500 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 can 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
send to IBM's Remote Technical
Assistance Information Network
(RETAIN).
T
TapeAlert
A patented technology from
Hewlett-Packard that monitors the status
of a tape device and media, and detects
problems as they occur.
TapeAlert flags
Status and error messages that are
generated by the TapeAlert utility and
display on the host console. The messages
indicate the type of problem and tell how
to resolve it.
tape cartridge
A removable storage device that consists
of a housing that contains a belt-driven
magnetic tape wound on a supply reel
and a takeup reel.
tape drive
A data-storage device that controls the
movement of the magnetic tape in a
compatible tape cartridge. The tape drive
houses the mechanism (drive head) that
reads and writes data to the tape.
tape frame
See IBM 3953 Tape Frame Model F05 .
Tape System Service Application (TSSA)
A set of software tools that reside on the
integrated management console (IMC)
that aid in both local service and remote
support of the attached TS4500 tape
