How to configure VMWare High Availability cluster using vCenter Server 6

In this post, we’ll learn the steps to configure VMWare High Availability Cluster using vCenter Server 6. VMWare High Availability i.e. HA is a great feature provided by VMWare. It is used to provide high availability of applications and servers. VMware High Availability can be configured on Cluster and we need to have more than one ESXi servers to configure HA. In addition to that we need to ensure that vMotion is working and all the Virtual Machines are hosted on Shared Storage.

I’ll quote an example before we configure VMWare High Availability cluster. Let’s take a scenario in which we have two VMWare ESXi Servers i.e. ESX01 and ESX02. They both are part of ProCluster and HA is configured on ProCluster. Assuming two Virtual Machines i.e. Node01 and Node02 are running on ESX01. In this scenario if ESX01 crashes then both the Node01 and Node02 machines would restart and then automatically powered-on on ESX02 server. There would be small outage for the duration while these machines are getting restarted but it can help in prevent major outages.
