A

tetrahedral topology

of 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.

tetrahedron

A solid bounded by four triangular faces. In ServerNet context, 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

.

tetrahedral topology

A topology of NonStop S-series servers in which the ServerNet connections between the
processor

enclosures

form a tetrahedron.

Token-Ring ServerNet adapter (TRSA)

A ServerNet adapter that provides a single line from a NonStop S-series server to a
token-ring network, allowing the server to act as a station on the ring. The 3862 TRSA
can be configured to support network speeds of 4 megabits/second (Mbps) or 16 Mbps,
and the media can be either shielded twisted pair (STP) or unshielded twisted pair (UTP).

topology

The physical layout of components that define a local area network (

LAN

). a system area

network (

SAN

), or a wide are network (

WAN

).

topology branch

A processor

enclosure

and the I/O enclosures directly connected to it.

track ID

A unique number assigned to

customer-replaceable unit (CRU)

and

field-replaceable

units (FRUs)

. The track ID is located on a label on the outside of the component, usually

following the assembly number of the component.

Transmission Control Protocol (TCP)

A connection-oriented protocol that provides for the reliable exchange of data between a
sending and a receiving system, no matter how many intermediate

nodes

the data

traverses. TCP, in conjunction with the

internet protocol (IP)

, is used to facilitate OSM

communications over an Ethernet local area network (

LAN

).

tree pane

Located on the left side of the

Management window

, a pane that displays resources in a

hierarchy. The tree pane contains a drop down menu with two options: System view and
