Cabling Your Cluster Hardware 23
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 located on
Dell Support website at support.dell.com.
NOTE: For more details on storage hardware settings and descriptions, see
Dell PowerVault™ MD3000i RAID Enclosure Hardware Owner's Manual.
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 MD3000i to use
out-of-band management.
Cabling the Cluster in a Non-Redundant Configuration
The non-redundant configuration provides only a single data path from a host
to the RAID enclosure, and is not recommended for applications that need
critical data storage. Path failure from a failed cable or a failed iSCSI NIC may
cause the application(s) to failover to the other cluster node. A failed RAID
controller module may cause loss of host access to storage and thus may result
in the cluster going down.
To cable the cluster:
1
Install a network cable from the cluster node 1 iSCSI NIC to the RAID
module 0 port In-0.
2 Install a network cable from the cluster node 2 iSCSI NIC to the RAID
module 0 port In-1.
