About campus clusters
Campus clusters are multiple-node clusters that provide protection against disasters. The nodes can be located in separate buildings miles apart. Nodes are located within a single subnet and connected by a Fibre Channel SAN. Each node has its own storage array and contains mirrored data of the storage on the other array.
Typical campus clusters involve two sites; you can use more than two sites for additional redundancy.
This environment also provides a simpler solution for disaster recovery than a more elaborate InfoScale disaster recovery environment with replication software; however, a campus cluster generally stretches a shorter distance than a replication-based solution depending on the hardware.
Both local clusters and campus clusters have SFW dynamic disk groups and volumes, but the volumes on each campus cluster node are mirrors of one another. Each disk group should contain the same number of disks on each site for the mirrored volumes.
The following figure shows an example of a two-node campus cluster configuration.
