General vRealize Operations Manager Cluster Node Requirements
When you create the cluster nodes that make up vRealize Operations Manager, you have general
requirements that you must meet.
General Requirements
n
vRealize Operations Manager Version. All nodes must run the same vRealize Operations Manager
version.
For example, do not add a version 6.1 data node to a cluster of vRealize Operations Manager 6.2 nodes.
n
Analytics Cluster Deployment Type. In the analytics cluster, all nodes must be the same kind of
deployment: vApp, Linux, or Windows.
Do not mix vApp, Linux, and Windows nodes in the same analytics cluster.
n
Remote Collector Deployment Type. A remote collector node does not need to be the same deployment
type as the analytics cluster nodes.
When you add a remote collector of a dierent deployment type, the following combinations are
supported:
n
vApp analytics cluster and Windows remote collector
n
Linux analytics cluster and Windows remote collector
n
Analytics Cluster Node Sizing. In the analytics cluster, CPU, memory, and disk size must be identical
for all nodes.
Master, replica, and data nodes must be uniform in sizing.
n
Remote Collector Node Sizing. Remote collector nodes may be of dierent sizes from each other or
from the uniform analytics cluster node size.
n
Geographical Proximity. You may place analytics cluster nodes in dierent vSphere clusters, but the
nodes must reside in the same geographical location.
Dierent geographical locations are not supported.
n
Virtual Machine Maintenance. When any node is a virtual machine, you may only update the virtual
machine software by directly updating the vRealize Operations Manager software.
For example, going outside of vRealize Operations Manager to access vSphere to update VMware Tools
is not supported.
n
Redundancy and Isolation. If you expect to enable HA, place analytics cluster nodes on separate hosts.
See About vRealize Operations Manager High Availability,” on page 27.
Requirements for Solutions
Be aware that solutions might have requirements beyond those for vRealize Operations Manager itself. For
example, vRealize Operations Manager for Horizon View has specic sizing guidelines for its remote
collectors.
See your solution documentation, and verify any additional requirements before installing solutions. Note
that the terms solution, management pack, adapter, and plug-in are used somewhat interchangeably.
