For a test platform, you may wish to allow users to work with more compute resources than are present in your servers.
To allow oversubscription for a test platform, create compute load level rules for CPU and RAM for each server.

Rule type | Select Load level compute | Rack | Select All or a specific rack | Server | Select All or a specific server. If you are using a cluster as a physical machine, select the "Server" radio button to create rules for the cluster | Cluster
| If you are using vCenter with ESXi, the platform detects the clusters. Select a specific cluster A cluster rule affects all hosts irrespective of their state, for example, it applies to hosts that are powered off. | Aggregate | Select to create a rule for the sum of all resources in a group (datacenters, racks, or clusters). This means that the platform will sum all of the resources in the group and calculate the load level percentage of the total in order to determine the available resources for the group. | Service Port | The port used by the cloud nodes to connect to the storage technology | RAM | Percentage usage of memory to allow. We DO NOT recommend the overallocation of RAM | CPU cores | Percentage usage of CPU cores to allow. We DO NOT recommend the oversubscription of CPU cores |
