Cabling Your Cluster Hardware 21
You must use the same brand of NICs in a team, and you cannot mix brands
of teaming drivers.
Cabling the Storage Systems
This section provides information for connecting your cluster to a storage
system.
NOTE: To configure Dell blade system modules in a Dell PowerEdge Cluster, see
Using Dell Blade Servers in a Dell PowerEdge High Availability Cluster
at
support.dell.com/manuals.
NOTE: For more details on storage hardware settings and descriptions, see
Dell PowerVault MD3200i and MD3220i RAID Enclosure Owner's Manual
at
support.dell.com/manuals.
Storage management can be either in-band through the host-to-controller
interface or out-of-band using an Ethernet connection. For out-of-band
storage management, cable the Ethernet ports on the storage array to the
public network.
NOTE: It is recommended that you configure your Dell PowerVault MD3200i and
MD3220i to use out-of-band management.
Cabling the Cluster in Direct-Attached Configuration
In the direct-attached configuration, each cluster node is directly attached to
the PowerVault MD3200i or MD3220i 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:
a
Install a network cable from the cluster node 1 iSCSI NIC 1 (or NIC
port 1) to the RAID controller module 0 port In-0.
