Installing a 1x1 Configuration With Software RAID-1
shows four storage arrays, and two have controllers. The first storage array
without a controller connects to the second storage array, which has a controller. The
third storage array without a controller connects to the fourth storage array, which has
a controller. The two storage arrays with controllers connect to a 2-node cluster
through two switches. Dual-controller configurations require software RAID-1
(host-based mirroring).
