NonStop System Glossary

tape load
A system load. A tape load is the process of reading a system image tape (SIT) and writing it to
the system disk. Performing a tape load from a SIT to restore the system image files to the $SYSTEM
disk is generally not recommended. Perform a tape load only with the advice of the GMCSC or
your service provider. Loading from a tape reinitializes the disk directory.
TAPE object type
The Subsystem Control Facility (SCF) object type for all tape drives attached to your system.
target system
The computer system you make larger by adding enclosures, using a process known as system
expansion. See also donor system.
TB
See terabyte (TB).
TCP
See Transmission Control Protocol (TCP).
TCP/IP
See Transmission Control Protocol/Internet Protocol (TCP/IP).
TEMPLI
The Event Management Service (EMS) template installation program that merges template object
files from specified subsystems and produces resident and nonresident template files.
terabyte (TB)
A unit of measurement equal to 1,099,511,627,776 bytes (1024 gigabytes). See also gigabyte
(GB), kilobyte (KB), and megabyte (MB).
terminal
A type of Open System Services (OSS) character special file that conforms to the interface description
in Clause 7 of ISO/IEC IS 9945-1:1990.
terminator
A resistor connected to a signal wire in a bus or network for the purpose of impedance matching
to prevent reflections. SCSI chains, Ethernet cables, and some LocalTalk wiring configurations
require terminators.
Tetra 8 topology
A tetrahedral topology of NonStop servers that allows a maximum of four processor enclosures
(eight processors) and eight I/O enclosures. Contrast with Tetra 16 topology.
Tetra 16 topology
A tetrahedral topology of NonStop servers that allows a maximum of eight processor enclosures
(16 processors). The maximum number of I/O enclosures allowed by the Tetra 16 topology varies
depending on the release version update (RVU) and the server model. Contrast with Tetra 8
topology.
