TB
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 HP NonStop™ S-series 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 HP NonStop™ S-series 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.
tetrahedral topology. A topology of HP NonStop™ S-series servers in which the ServerNet
connections between the processor enclosures form a tetrahedron. See also
tetrahedron and topology.
tetrahedron. A geometric solid with four vertices. The edges of the tetrahedron represent
connections between the vertices in which each vertex connects to all other vertices.
For ServerNet, a tetrahedron is four processors interconnected by ServerNet links so
as to form a conceptual tetrahedron. Each processor therefore has a direct connection
to the other three processors. See tetrahedral topology.
text string. A variable-length sequence of ASCII characters, defined in the CONFTEXT file,
that an identifier represents. When Distributed Systems Management/Software
Configuration Manager (DSM/SCM) encounters an identifier, it substitutes the
associated text string for the identifier.
TF. See time factor (TF).
TFDS. See HP Tandem Failure Data System (TFDS).
TFTP. See Trivial File Transfer Protocol (TFTP).
