Sun Cluster 3.0-3.1 Hardware Administration Manual for Solaris OS

A two-room configuration with host-based data replication is defined as follows:

If the room containing the quorum disk is lost, the system cannot recover automatically. Recovery requires intervention from your Sun service provider.

Figure A–1 shows a sample two-room configuration with storage arrays in each room.

Figure A–1 Example Two-Room Campus Cluster With Host-Based Data Replication (No Multipathing)

Illustration: The preceding and following contexts describe
the graphic.

Figure 7–7 is similar to a standard noncampus configuration. The most obvious difference is that FC switches have been added to switch from multimode to single-mode fibers.
