Using the Long-Distance Option
This appendix provides information on the long-distance option between zones.
Starting with the G06.22 RVU, the HP NonStop ServerNet Switch (model 6780) can
support significantly longer zone-to-zone connections in a ServerNet cluster. Software,
firmware, and configuration files enable you to have zone-to-zone connections
between 5 and 15 kilometers (km). To accommodate the longer distances, the
supporting software sets the links to a capacity of 50 megabytes per second.
