Example SAN configurations
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.
SAN fabric function is available only if a Fibre Channel option is installed. Otherwise, this information does not apply.
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 Storwize® V3700,
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 Storwize V3700 control enclosure and external storage system to two fabrics. The example fabric attaches the Storwize V3700 control enclosure and the storage systems to the core switch. There
are no ISL hops between Storwize V3700 node
canister ports or between the control enclosure and the external storage systems.
