Data Object - ClusterFailoverResourcesAdmissionControlPolicy
- vSphere API 4.0
reserves a specified percentage of aggregate cluster resources for failover.
With the resources failover policy in place, VMware HA uses the following
calculations to control virtual machine migration in the cluster.
- Calculate the total resource requirements for all powered-on
virtual machines in the cluster.
- Calculate the total host resources available for virtual machines.
- Calculate the Current CPU failover capacity and current memory failover
capacity for the cluster.
- Compare the current CPU failover capacity and current memory failover
capacity with the configured resource percentages
If either current capacity is less than the corresponding configured
capacity, HA does not allow the operation.
HA uses the actual reservations of the virtual machines. If a virtual machine
does not have reservations, meaning that the reservation is 0, a default
of 0MB memory and 256MHz CPU is applied. This is controlled by the same
HA advanced options used for the failover level policy
Percentage of CPU resources in the cluster to reserve for failover.
You can specify up to 100% of CPU resources for failover.
Percentage of memory resources in the cluster to reserve for failover.
You can specify up to 100% of memory resources for failover.
