Cabling Your Cluster Hardware 25
Cabling Multiple iSCSI SAN-Attached Clusters to a Dell|EMC Storage System
To cable multiple clusters to the storage system, connect the cluster nodes to
the appropriate iSCSI switches and then connect the iSCSI switches to the
appropriate storage processors on the processor enclosure.
For rules and guidelines for iSCSI SAN-attached clusters, see the Dell Cluster
Configuration Support Matrices located on the Dell High Availability Cluster
website at www.dell.com/ha.
Cabling Multiple iSCSI SAN-Attached Clusters to the AX4-5i Storage System
NOTE: The following procedure uses Figure2-8 as an example for cabling
additional clusters.
1
In the first cluster, connect cluster node 1 to the iSCSI network.
a
Connect a network cable from iSCSI NIC 0 (or NIC port 0) to the
network switch 0 (sw0).
b
Connect a network cable from iSCSI NIC 1 (or NIC port 1) to the
network switch 1 (sw1).
2
In the first cluster, repeat step1 for each node.
3
For each additional cluster, repeat step1 and step 2.
4
Connect the storage system to the iSCSI network.
a
Connect a network cable from the network switch 0 (sw0) to SP-A
iSCSI port 0.
b
Connect a network cable from the network switch 0 (sw0) to SP-B
iSCSI port 1.
c
Connect a network cable from the network switch 1 (sw1) to SP-A
iSCSI port 1.
d
Connect a network cable from the network switch 1 (sw1) to SP-B
iSCSI port 0.
Connecting a PowerEdge Cluster to Multiple Storage Systems
You can increase your cluster storage capacity by attaching multiple storage
systems to your cluster using redundant iSCSI networks. PowerEdge cluster
systems can support configurations with multiple storage units attached to
the clustered nodes. In this scenario, the MSCS software can fail over disk
drives in any cluster-attached shared storage array between the cluster nodes.
