Installation and Configuration 5-5 Cabling the Host Adapters to Fibre Channel SAN Switches or Storage Hubs Each redundant Fibre Channel Fabric requires at least two Fibre Channel SAN Switches and each redundant FC-AL requires at least two Storage Hubs. For detailed cabling guidelines, refer to the sections entitled "I/O Path Configurations for Redundant Fibre Channel Fabrics" and "I/O Path Configurations for Redundant Fibre Channel Arbitrated Loops" in Chapter 2, "Cluster Architecture." To cable the host adapters to the Fibre Channel SAN Switches or Storage Hubs: 1. Using Fibre Channel cables, connect host adapter #1 in each server to Fibre Channel SAN Switch #1 or Storage Hub #1. 2. Using Fibre Channel cables, connect host adapter #2 in each server to Fibre Channel SAN Switch #2 or Storage Hub #2. 3. Repeat steps 1 and 2 for all other host adapters in each server and additional Fibre Channel SAN Switches or Storage Hubs. Connect like-numbered host adapters across servers to the same Fibre Channel SAN Switch or Storage Hub. Figure 5-1 shows two host adapter in two servers connected to two Fibre Channel SAN Switches or Storage Hubs.
