Examples of typical ways to configure your system and an associated Fibre Channel network
are provided to guide you in setting up your SAN configuration.
Note: The illustrations in these
examples do not show expansion enclosures as they have no relationship to SAN connectivity.
Figure 1 illustrates a small SAN configuration. Two
Fibre Channel switches are used to provide redundancy. The control enclosures and each host system
are connected to both Fibre Channel switches. If you are using external storage systems with the system, connect as
shown in this illustration. Figure 1. Simple SAN configuration
Figure 2 illustrates a medium-sized configuration with
external storage systems. The Fibre
Channel SAN fabric consists of switches that are interconnected with interswitch links (ISLs). For
redundancy, connect each control enclosure and external storage system to two fabrics. The example
fabric attaches the control enclosures and the storage systems to the core switch. No ISL
hops exist between node canister ports or between the control enclosures and the external storage systems. Figure 2. SAN configuration with a medium-sized fabric
