Maximum Distances Between Nodes and Shared
Storage Components in a Redundant Fibre Channel
Fabric
By using standard short-wave Fibre Channel cables with Gigabit Interface
Converter-Shortwave (GBIC-SW) modules, the following maximum distances
apply:
■ Each RA4000/RA4100 Array can be placed up to 500 meters from the
Fibre Channel SAN Switches to which it is cabled.
■ Each Fibre Channel SAN Switch can be placed up to 500 meters from
the Fibre Host Adapters to which it is cabled.
Figure 2-3 illustrates these maximum cable distances for a redundant Fibre
Channel Fabric.
