vSphere DRS ensures optimal resource allocation across the VMs in your SDDC. In an on-premises environment, you can configure several options, for example, you can use fully automated DRS or decide to receive recommendations. In a VMware Cloud on AWS SDDC, VMware has preconfigured the vSphere DRS options for the cluster of hosts.
VMware has selected settings that ensure optimal resource distribution while minimizing the number of migrations that occur. You don't have to - and you can't - change those selections. You might find it interesting to look at the preconfigured values.
- In the vSphere Client, click Menu and select Hosts and Clusters.
- Select Cluster-1.
In VMware Cloud on AWS, a single cluster holds the configuration settings. Because the settings are predefined, a second cluster is not needed.
- Examine the DRS settings, which fully automate resource allocation across the cluster.
The UI explains the background information. For detailed information, see the vSphere Resource Management documentation.
