Table 1‑1. Effect of Deployment Conditions on Complexity (Continued)
Complexity Level
Current or New Deployment
Condition Additional Notes
Red Your current
vRealize Operations Manager
deployment required a Professional
Services engagement to install it.
If your environment was complex
enough to justify a Professional
Services engagement in the previous
version, it is possible that the same
conditions still apply and might
warrant a similar engagement for this
version.
Red Professional Services customized
your vRealize Operations Manager
deployment. Examples of
customization include special
integrations, scripting, nonstandard
congurations, multiple level
alerting, or custom reporting.
If your environment was complex
enough to justify a Professional
Services engagement in the previous

conditions still apply and might
warrant a similar engagement for this
version.
vRealize Operations Manager Cluster Nodes
All vRealize Operations Manager clusters consist of a master node, an optional replica node for high
availability, optional data nodes, and optional remote collector nodes.
When you install vRealize Operations Manager, you use a vRealize Operations Manager vApp deployment,
Linux installer, or Windows installer to create role-less nodes. After the nodes are created and have their
names and IP addresses, you use an administration interface to congure them according to their role.
You can create role-less nodes all at once or as needed. A common as-needed practice might be to add nodes
to scale out vRealize Operations Manager to monitor an environment as the environment grows larger.
The following node types make up the vRealize Operations Manager analytics cluster:
Master Node
The initial, required node in vRealize Operations Manager. All other nodes
are managed by the master node.
In a single-node installation, the master node manages itself, has adapters
installed on it, and performs all data collection and analysis.
Data Node
In larger deployments, additional data nodes have adapters installed and
perform collection and analysis.
Larger deployments usually include adapters only on the data nodes so that
master and replica node resources can be dedicated to cluster management.
Replica Node
To use vRealize Operations Manager high availability (HA), the cluster
requires that you convert a data node into a replica of the master node.
The following node type is a member of the vRealize Operations Manager cluster but not part of the
analytics cluster:
Remote Collector Node
Distributed deployments might require a remote collector node that can
navigate rewalls, interface with a remote data source, reduce bandwidth
across data centers, or reduce the load on the vRealize Operations Manager
analytics cluster. Remote collectors only gather objects for the inventory,
without storing data or performing analysis. In addition, remote collector
nodes may be installed on a dierent operating system than the rest of the
cluster.
