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 Lenovo Storage V series,
connect as shown in this illustration.

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 Lenovo Storage V series control
enclosure and external storage system to two fabrics. The example fabric
attaches the Lenovo Storage V series control
enclosures and the storage systems to the core switch. There are no ISL hops between Lenovo Storage V series node
canister ports or between the control enclosures and the external storage systems. The example fabric attaches
the Lenovo Storage V series control enclosure and the storage systems to the core switch. There are no ISL hops between Lenovo Storage V series node
