Feature codes for Fibre Channel cables
Use these feature codes to order Fibre Channel cables to connect Fibre Channel
host adapters. Take note of the distance capabilities for cable types.

Configuration rules for host adapters

Use the following configuration rules and ordering information to help you order
host adapters.
When you configure your storage system, consider the following issues when you
order the host adapters:
v How many host adapters will I install? You can install either two or four in
v How can I balance the host adapters across the storage system to help ensure
v What host adapter configurations help ensure high availability of my data?
