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.
