This external documentation for pyVmomi was generated using Googly Docs (aka Google Standard Documentation) which renders very cleanly in GitHub. Internal documentation for a class should be done in Sphinx format because tools like pyCharm and Eclipse can use that documentation as a hint for code completion. Note: External docs as Googly Docs, internal docs as Sphinx. Closes bug#15

vim.cluster.FailoverResourcesAdmissionControlPolicy
|
|
===================================================
|
|
The `ClusterFailoverResourcesAdmissionControlPolicy`_ reserves a specified percentage of aggregate cluster resources for failover. With the resources failover policy in place, vSphere 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 (
|
|
* `cpuFailoverResourcesPercent`_
|
|
* and
|
|
* `memoryFailoverResourcesPercent`_
|
|
* ). 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 (
|
|
* `ClusterFailoverLevelAdmissionControlPolicy`_
|
|
* ).
