Switch Modules

ServerNet Nomadic Disk (Release 2) User’s Guide—523968-001

4-2

Switch modules control ownership of the disk modules and data paths. To control

switch modules, you can either:

•

Physically toggle a switch on a switch card

•

Use software, such as the ServerNet Nomadic Disk switch command interface

(SWCI) or the Nomadic Disk Manager

Figure 4-1 shows the faceplate of a switch module.

Switch modules contain:

•

A switch controller card (SCC) in slot 0, which provides a communication link

between switch cards and a server.

•

Switch cards in slots 1 through 8, which determine the path of fiber-optic signals

between a node and the internal 46xx or external 45xx disk drives.

Note. Although it is possible to connect other types of servers to the switch module, NonStop

S-series servers are the only servers documented in this guide.
