To ensure optimal vSphere HA cluster performance, you should follow certain best practices. This topic highlights some of the key best practices for a vSphere HA cluster. You can also refer to the vSphere High Availability Deployment Best Practices publication for further discussion.
When vSphere HA or Fault Tolerance take action to maintain availability, for example, a virtual machine failover, you can be notified about such changes. Configure alarms in vCenter Server to be triggered when these actions occur, and have alerts, such as emails, sent to a specified set of administrators.
Several default vSphere HA alarms are available.

The default alarms include the feature name, vSphere HA.
This is part 5 of the Cisco UCS Configuration Guide, covering the creation of Cisco UCS Server policies. Eight part series, describing how to configure a Cisco UCS from start to finish for a vSphere deployment: Cisco UCS Configuration Guide – Part 1 – Overview Cisco UCS Configuration Guide – Part 2 – Equipment Cisco. After I installed VMware Tools on virtual machine its resolution adjusts to the console window size automatically. It is not what I want - I want that the resolution of my virtual machine stays the same. It is VMware ESXi 6.5, where is only web console available. It is happening only after installing VMware Tools (i need it of course).
A valid cluster is one in which the admission control policy has not been violated. Chances games casino.
A cluster enabled for vSphere HA becomes invalid when the number of virtual machines powered on exceeds the failover requirements, that is, the current failover capacity is smaller than configured failover capacity. If admission control is disabled, clusters do not become invalid.
In the vSphere Web Client, select vSphere HA from the cluster's Monitor tab and then select Configuration Issues. A list of current vSphere HA issues appears.
In the vSphere Client, the cluster's Summary tab displays a list of configuration issues for clusters. The list explains what has caused the cluster to become invalid or overcommitted.

DRS behavior is not affected if a cluster is red because of a vSphere HA issue.
vSphere HA and Storage vMotion Interoperability in a Mixed Cluster
In clusters where ESXi 5.x hosts and ESX/ESXi 4.1 or prior hosts are present and where Storage vMotion is used extensively or Storage DRS is enabled, do not deploy vSphere HA. vSphere HA might respond to a host failure by restarting a virtual machine on a host with an ESXi version different from the one on which the virtual machine was running before the failure. A problem can occur if, at the time of failure, the virtual machine was involved in a Storage vMotion action on an ESXi 5.x host, and vSphere HA restarts the virtual machine on a host with a version prior to ESXi 5.0. While the virtual machine might power on, any subsequent attempts at snapshot operations could corrupt the vdisk state and leave the virtual machine unusable.
The following recommendations are best practices for vSphere HA admission control.

You can use vSphere HA and Auto Deploy together to improve the availability of your virtual machines. Auto Deploy provisions hosts when they power up and you can also configure it to install the vSphere HA agent on such hosts during the boot process. See the Auto Deploy documentation included in vSphere Installation and Setup for details.
