Virtual Machine Restart During Host Failure

[dya]

When a host fails, virtual machines are restarted on another host. How long does it take from the host failure to the virtual machine restart?
I believe it's approximately 3 minutes.

Also, can this time be changed in the settings?

*Apologies if this is unclear due to machine translation.

This happens by default on a "Cluster Sync", which occurs (by default) every 5 minutes.  When the VM Essentials Manager detects host down/VM's down, it will restart those VM's on another host.

This 5-minute interval can be changed in the VM Essentials Manager Settings.

BUT!  If you enable Datastore Heartbeating (check the box of 1 (preferably 2 ) Datastores), the failure will be detected within seconds and the failover/restart of the VM's will also happen within seconds.

You can also control how VM's will failover via the "Managemt Placement" setting of a VM.

Thank you for your prompt response.

This is an environment with datastore heartbeat enabled.
As a test, changing the cluster synchronization settings does not seem to alter the time from host failure to virtual machine restart.

Below are the verification results. It appears to take approximately 3 minutes.
Is it correct to understand that this time cannot be adjusted when datastore heartbeat is enabled?

■Cluster Sync - default(300)
2 minutes 46 seconds

■Cluster Sync - 600
2 minutes 42 seconds
