NOTE: HP does not recommend the ring fabric for applications requiring many-to-many
connectivity.
Figure 5 Ring fabric
25093a
If the ring fabric has fewer than 12 switches, you can add switches (called satellite switches) outside
the ring to create more user ports (Figure 6). Satellite switches are not supported.
NOTE: Adding satellite switches slightly reduces fabric availability.
For more information on switch fabric maximums, see:
• “B-series switches and fabric rules” (page 91)
• “C-series switches and fabric rules” (page 123)
• “H-series switches and fabric rules” (page 140)
