Cabling Your Cluster Hardware

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.
• The shared storage systems and firmware must be identical. Using
dissimilar storage systems and firmware for your shared storage is not
supported.
