VMware vRealize Operations Manager Step by Step (Part-2) Architecture and High Availability


In this post we will go through the architecture of the product, also we we will go through step by step how to configure the high availability for the vRops by creating Master Replica for the master node of the cluster,

vRealize operations Manager Design Architecture considerations and  Node Types:

  • Master Node

The Master node is the initial node in your vRealize Operations Manager cluster. if we are planning to have a Single-Node Cluster so the administration and the data are on the same master node, if we are planning to have a Multi-Node Cluster which will include one Master and one or more data nodes,

  • Master Replica Node

Enabling the Master Replica Node is the key of having the High availability for the vRealize Operations Manager, if we have a problem occurred with the Master node for any reason, a failover to the replica node will occur automatically,

  • Data Node

Data nodes are the additional cluster nodes that allow you to scale out vRealize Operations Manager to monitor larger environments. to perform collection and analysis. On the Larger deployments usually adapters are only installed and configured on data nodes,

  • Remote Collector Node

On the large environment we might have a distributed deployment across sites, then we will need a remote collector node that can navigate firewalls and reduce bandwidth across data centers, Remote collectors only gather objects for the inventory, without storing data or performing analysis,

Now lets start our deployment of the Master Replica Node to provide the high availability, We will start with deploying another vRops OVF same as we did earlier, We will access it through web URL access,

Give a name to the Node

Select Node Type: (Data or Remote Collector)

Insert the IP address of the Master Node and Click Validate, Check Accept the Certificate,

Click Next,

Review and Click Finish,

Now we have deployed our first Data Node,

Check the Status of the High Availability you will find it Disabled, and its not available to enable it because the master node is Powered on and Online,

We will Power of the Master node from the Power button,

Once the Master node go Offline we can now start the process of enabling the High Availability, Click Enable

Check “Enable High Availability for this Cluster” and Click OK

Check the name of the Cluster Role, its changed from Data to Master Replica, also you will find the status of the HA changed to Enabled,

Last status is to bring all online, click on Bring Online

Here we go ………… Smile

We have our Highly available vRealize Operations Manager Cluster up and run with 2 nodes Cluster (Master and Master Replica)

Next Post we talk about the Sizing and the Calculator
