Cabling Multiple SAN-Attached Clusters to a Dell/EMC Storage System To cable multiple clusters to the storage system, connect the cluster nodes to the appropriate Fibre Channel switches and then connect the Fibre Channel switches to the appropriate storage processors on the processor enclosure. See the Dell Cluster Configuration Support Matrices located on the Dell High Availability Clustering website at dell.com/ha for rules and guidelines for SAN-attached clusters. NOTE: The following procedure uses Figure 2-9 as an example for cabling additional clusters. Cabling Multiple SAN-Attached Clusters to the AX4-5 Storage System 1 In the first cluster, connect cluster node 1 to the SAN. a Connect a cable from HBA port 0 to Fibre Channel switch 0 (sw0). b Connect a cable from HBA port 1 to Fibre Channel switch 1 (sw1). 2 In the first cluster, repeat step 1 for each node. 3 For each additional cluster, repeat step 1 and step 2. 4 Connect the storage system to the SAN. a Connect a cable from Fibre Channel switch 0 (sw0) to SP-A Fibre port 0(first fibre port). b Connect a cable from Fibre Channel switch 0 (sw0) to SP-B Fibre port 1(second fibre port). c Connect a cable from Fibre Channel switch 1 (sw1) to SP-A Fibre port 1(second fibre port). d Connect a cable from Fibre Channel switch 1 (sw1) to SP-B Fibre port 0(first fibre port). Connecting a PowerEdge Cluster to Multiple Storage Systems You can increase your cluster storage capacity by attaching multiple storage systems to your cluster using a redundant switch fabric. PowerEdge cluster systems can support configurations with multiple storage units attached to clustered servers. In this scenario, the MSCS software can fail over disk drives in any cluster-attached shared storage array between the cluster nodes. When attaching multiple storage systems with your cluster, the following rules apply: • There is a maximum of four storage systems per cluster. 30 Cabling Your Cluster Hardware
