Configure Cluster DRS and High Availability

Hi guys,

In this tutorial, I am going to show you how to configure DRS and High availability cluster in our center, But before we getting start this tutorial, let’s talk a little bit about these features.

Dynamic Resource Scheduler – is a very common cluster which allows us the automatic mechanism of the load balancer, it means that it knows how to divide the resources according to what we will configure.

High Availability – provide us HA between our hosts, if a physical server is failed the HA will restart the guest to another HOST by migration process and it reduces the downtime.

Admission Control – manage the cluster resources, we can set that give back the exact resources as the machine had. A good feature, There are 3 EXSI and 1 ESXI failed, unexpectedly, so I set that it distributes all machines between two ESXI only or specific ESX
