6.7 Case 6: Shared FDDI Backbone
Goal
Migrate to a larger network with a shared dual FDDI Backbone.
Design Requirements
• Migration of the local shared workgroups of up to 192 users to higher band-
width.
• Provide FDDI shared network servers.
• Have network management.
Suggested Configuration
• Platform types:
– DEChub 900 MultiSwitch (three)
• Network Modules:
– DECswitch 900EF
– DECconcentrator 900MX. These are only needed for local servers or other
FDDI devices.
– DECrepeater 900TM
• clearVISN network management software.
Once the hardware has been installed, the clearVISN MultiChassis Manager soft-
ware is used to configure the hubs and modules.
Options:
All DECserver 900TMs can be replaced with PORTswitch 900TPs to allow balanc-
ing of the Ethernet loads.
Figure 6–11 shows the hardware implementation.
