Pathlight VX and an External Aggregation Switch
Depending on the type of physical library and number of physical libraries attached to the Pathlight VX, an
external aggregation device (an FC switch) may need to be used with the Pathlight VX so the required
number of port connections are available. ADIC recommends that a Brocade FC switch be used as an
aggregation device. Although you can provide use a different vendor’s FC switch for aggregation, ADIC only
provides technical support for a Brocade FC switch used with the Pathlight VX.
For information about whether an external aggregation switch is needed for the Pathlight VX contact a pre-
sales Service Engineer at ADIC (refer to Getting More Information or Help
on page 4) and see the external
aggregation device paths in Figure 10
(for Entry-Level Configurations), Figure 11 on 14 (for Standard
Configuration), and Figure 12
on 14 (for High-Performance Configurations).
