This process needs to be repeated for the second FC3171 8Gb SAN Switch in the chassis so
as to allow for redundancy by using both fabrics in the chassis.

11.5.4 Multipathing
The above example has created a single zone which includes the initiator from the x240
compute node and two targets, one from each of the storage node canisters. From a compute
node host perspective it now has two paths through the FC switch to the IBM Flex System
V7000 Storage Node. Repeating the process on the second IBM Flex System Enterprise
Chassis FC switch, two more paths are included to the compute node for storage node
access. With the compute node host operating system device drivers, it will now have the
capability with multipathing to use the four paths available to it. This provides an
enhancement for availability and storage performance to the host system on the compute
node.

11.5.5 FC Switch Transparent Mode and NPIV
The IBM Flex System FC3171 8Gb SAN Switch used in the zoneset and zone creation
example (section 11.5.3, “Zoning a Compute Node for Storage Allocation” on page 460)
shows where it has the full functionality of an FC switch. It can connect to an external FC SAN
fabric as shown in Figure 11-19 on page 459. The switch can also be configured into
‘Transparent Mode’ where it will connect to an external FC SAN switch using F_Port-N_Port
instead of E-Port-E-Port connectivity. From the external SAN and switches all zoning
example (section 11.5.3, “Zoning a Compute Node for Storage Allocation” on page 460)
