Notes:
1. The DCS3700 ships with eight 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.
2. Installation of the optional 8Gbps 4 port Fibre Channel host interface card is required in both
controllers in order to support fibre channel host connections.
To connect a fibre channel 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.
3. Repeat steps 1 and 2 for an additional redundant host connection. In a direct connection
configuration, you can create a maximum of four redundant host connections for the storage
subsystem.
See “Direct-attached dual-controller connections:” and “SAN fabric dual-controller, redundent
connections” on page 63for illustrations of host connections.
Direct-attached dual-controller connections:
The following illustration shows a direct-attached connection from each controller to a single HBA in the
same host (redundant host connection).
