The platform uses allocation rules to control the scheduling of resources in private cloud datacenters, to deploy your VMs to the desired hosts. Your virtualization technology must manage the use of resources in the virtualization technology.
...
There are two types of allocation rules: Global rules apply to all datacenters and Datacenter rules apply to the selected datacenter.
You can manage Allocation allocation rules on the datacenter Allocation rules tab.
For details of Allocation allocation limits, see Control resource usage with allocation limits
...
For You can create the following types of load balance rules:
PERFORMANCE: select the physical machine with the most available resources. If more than one physical machine has the same resources available, use a round-robin algorithm to allocate each VM to a different physical machine.PROGRESSIVE: select the same physical machine until it is full, then change to another one. Begin with the machine with the most available resources. Default This is the default rule.
A datacenter load balance rule will have priority over a global load balance rule.
Privileges: Access infrastructure view and Private DCs, View datacenter details, Manage allocation rules
...
To specify the CPU and RAM load on machines, use compute load level rules. The scheduler will use these rules to help determine if a physical machine is a candidate to hold a VM.

The platform uses Load load level rules to specify the level that the scheduler can assign to the virtualization technology. The virtualization technology is responsible for managing the load that is assigned |
...
The priority order of rules is any cluster rule first (if it is present), then the other rules from the most specific rule to the least specific rule. A cluster rule affects all hosts in a cluster irrespective of their state, for example, it applies to hosts that are powered off.
An aggregate rule will apply to 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.
If you are using a cluster as a physical machine, to create rules for the cluster, select the Server option.
...
Load level storage rules
To specify the storage load on machine datastores, use storage load level rules. The scheduler will use these rules to help determine if a physical machine is a candidate to hold a VM.
