Connecting Fibre Channel hosts to the DS3500

Using Fibre Channel switches, up to 64 hosts can be redundantly attached to the DS3500 storage
subsystem in a Fibre Channel storage area network (SAN) fabric.
Note: The DS3500 ships with four storage partitions by default. For additional storage partitions,
purchase an optional Storage Partition Premium Feature upgrade. Contact your IBM reseller or marketing
representative for more information.
To connect a host to the controllers, complete the following steps:
1. Install SFP modules in the host ports on controllers A and B.
2. Connect the Fibre Channel cables to the SFP modules in the controller host ports and to either the SFP
modules in the Fibre Channel switch or the optical interface connector on the host bus adapters.
Figure 3-40 on page 3-35 shows the location on the controllers of the storage subsystem ports where
the host-system cables connect.
