Overview
V-Class Server Architecture
Each CTI controller connects to a corresponding CTI controller on a
remote cabinet by cables that provide both send (local-to-remote) and
receive (remote-to-local) connections among the cabinets.
Figure 11 Four-Cabinet V2500/V2600 Server CTI Cable Connections
Two dimensions of CTI connections are possible. Y-dimension cables
connect between cabinets 0 and 2, and between cabinets 6 and 4. X-
dimension cables connect cabinets 0 and 4, and cabinets 6 and 2.
Send and receive connections are provided in two dimensions on each
controller, for a total of four connections per controller possible. In a two-
cabinet server, cabinets 0 and 2 are connected via Y-dimension
CTI cables only. For a three-cabinet server, cabinet 0 has Y-dimension
CTI connections to cabinet 2 and X-dimension CTI connections to
cabinet 4.
For Y-dimension connections, CTI cables connect to their counterparts on
the remote cabinet. For example, the CTI cable connects from “Y-send” on
memory board 0 to the remote cabinet’s “Y-receive” on memory board 0.
