tetrahedral topology
A topology of NonStop S-series servers in which the ServerNet connections between the
processor
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 (
). a system area
).

topology branch
A processor
and the I/O enclosures directly connected to it.
track ID
customer-replaceable unit (CRU)
and
. 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
traverses. TCP, in conjunction with the
, is used to facilitate OSM
communications over an Ethernet local area network (
).
tree pane
Located on the left side of the
, a pane that displays resources in a
hierarchy. The tree pane contains a drop down menu with two options: System view and
ServerNet Cluster view. The System view bears the name of the local system and
displays resources within the system. The ServerNet Cluster view displays resources in a
supported Expand network, such as a ServerNet cluster.

tri-star topology
that uses up to three HP NonStop Cluster Switches for each external
fabric. External routing is implemented between the three star groups of a ServerNet
cluster. (A star group consists of the eight nodes attached to one set of cluster switches.)
