Cluster Switches
The cluster switches route packets between ServerNet nodes on the external
ServerNet X and Y fabrics of a ServerNet cluster. There are two cluster switches: the
6770 HP NonStop Cluster Switch and the HP NonStop ServerNet Switch (model
6780).
The 6770 HP NonStop Cluster Switch consists of the following components:
•
ServerNet II Switch
•
Uninterruptible power supply (UPS)
•
AC transfer switch
Figure 2-13 shows the 6770 HP NonStop Cluster Switch in the switch enclosure. (For
information about the 6780 switch, see the ServerNet Cluster 6780 Planning and
