We are plannig on creating a two-node, Unix cluster, with one site on node1 and three sites on node2. Everything will be running off a SAN with 4 volumes – Home = /home/hci/ directories; Integrator = /integrator/qdx5.5/integrator/ non-site directories; Site1 = root/site_a; Site2 = root/site_b, root/site_c, root/site_d.
