One of the first things you will configure in vCenter Server is

  • Create a datacenter
  • Create a HA and DRS cluster
  • Add an ESX/ESXi host

 

Start the vSphere client and connect to the vCenter Server.

 

Once connected right click the vCenter server hostname in the inventory,

Click "New Datacenter".

 

Give the Datacenter a name that describes its location.

 

Right click the datacenter and click "New Cluster".

 

Firstly give the cluster a sensible name. This could describe the processor type, the rack that the cluster of servers will be in, its use etc.

Select "Turn on VMware HA"

Select "Turn on VMware DRS"

Click Next.

 

VMware DRS will be discussed in more detail in another article.

To setup a fully automated DRS cluster choose "Fully automated" and a desired migration threshold.

Click Next.

 

VMware DRS Power Management will be discussed in more detail in another article.

Choose "Off" and Click Next.

 

VMware HA will be discussed in more detail in another article.

Select "Enable Host Monitoring".

Choose to prevent or allow VMs from being powered on if it violates availability constraints in a failure.

Click Next.

 

Choose to enable VM monitoring via VMware Tools.

Select the sensitivity for monitoring.

Click Next.

 

Chose "Disable EVC".

Click Next.

 

For the swapfile policy choose "Store the swapfile in the same directory as the virtual machine" (This will speed up VMotion).

Click Next.

Click Finish.

 

The HA DRS cluster is created. 

 

Right click the cluster and select "Add Host...".

 

Enter the hostname of the ESX/ESXi Server host.

Enter a password for the host.

Click Next.

Click Next.

 

Choose where to put any existing virtual machines on the host. Either:

In the root resource pool.

A new resource pool named after the host.
