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 RAID controllers, complete the following steps:
1. Install SFP modules in the host ports on RAID controllers A and B.
2. Connect the Fibre Channel cables to the SFP modules in the RAID 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 48 on page 54
shows the location on the RAID controllers of the storage subsystem ports
where the host-system cables connect.
