Redundant DX Cluster Services Nodes

The Dell DX Storage Cluster supports redundant DX Cluster Services Nodes.

In a redundant model, the active DX Cluster Services Node is configured as

the primary node and the redundant node is configured as the secondary

node, see Figure 2-2.

The primary Cluster Services Node contains the cluster configuration files,

active networking utilities, and active content router services. A manual

failover process is required to demote the primary DX Cluster Services Node

and promote the secondary DX Cluster Services Node. Since there is a

combined virtual IP address for the primary DX Cluster Services Node, a

failover to a redundant DX Cluster Services Node is transparent to all

applications. When a failover is transparent, an IP address change is not

required. However, the application services remain unavailable until the

manual failover of the Cluster Services Node is complete. For more

information, see the Cluster Services Installation and Configuration Guide at

support.dell.com/manuals.
