Cabling The Cluster In Direct-Attached Redundant Configuration - Dell powervault md3000i Installation And Troubleshooting Manual

Cabling the Cluster in Direct-Attached Redundant Configuration

In the direct-attached redundant configuration, each cluster node is directly
attached to the PowerVault MD3000i RAID controller modules using two
network cables, and either one dual-port NIC or two single-port NICs.
If a component fails in the storage path such as the port, the cable, or the
storage controller, the multipath software automatically re-routes the I/O
requests to the alternate path so that the storage array continues to operate
without interruption. The configuration with two single-port NICs provides
higher availability; a NIC failure does not cause failover cluster to move
cluster resources to the other cluster node.
To cable the cluster:
1 Connect cluster node 1 to the storage system:
Install a network cable from the cluster node 1 iSCSI NIC 1 (or NIC
a
port 1) to the RAID controller module 0 port In-0.
Install a network cable from the cluster node 1 iSCSI NIC 2 (or NIC
b
port 2) to the RAID controller module 1 port In-1.
2 Connect cluster node 2 to the storage system:
Install a network cable from the cluster node 2 iSCSI NIC 1 (or NIC
a
port 1) to the RAID controller module 0 port In-1.
Install a network cable from the cluster node 2 iSCSI NIC 2 (or NIC
b
port 2) to the RAID controller module 1 port In-0.
