About vRealize Operations Manager Data Nodes
Data nodes are the additional cluster nodes that allow you to scale out vRealize Operations Manager to
monitor larger environments.
A data node always shares the load of performing vRealize Operations Manager analysis and might also
have a solution adapter installed to perform collection and data storage from the environment. You must
have a master node before you add data nodes.
You can dynamically scale out vRealize Operations Manager by adding data nodes without stopping the
vRealize Operations Manager cluster. When you scale out the cluster by 25% or more, you should restart the
cluster to allow vRealize Operations Manager to update its storage size, and you might notice a decrease in
performance until you restart. A maintenance interval provides a good opportunity to restart the
vRealize Operations Manager cluster.
In addition, the product administration options include an option to re-balance the cluster, which can be
done without restarting. Rebalancing adjusts the vRealize Operations Manager workload across the cluster
nodes.
N Do not shut down online cluster nodes externally or by using any means other than the
vRealize Operations Manager interface. Shut down a node externally only after taking it oine in the
vRealize Operations Manager interface.

Run the Setup Wizard to Add a Data Node
Larger environments with multiple-node vRealize Operations Manager clusters contain one master node
and one or more data nodes for additional data collection, storage, processing, and analysis.
