What exactly happens when the vCenter server crashes

Hi All,


I need to know What exactly happens when the vCenter server crashes.

I know that the database and logs would be lost if the vCenter Server crashes, but I need to know what will happen to the Guest VMs which are connected via vDS, will they be available on the network and for how long.

Also where are the settings for vDS saved.

My Guest VMs are always available/reachable when the vCenter server goes for a reboot(45 mins reboot cycle).

Thanks all in advance

The vDS is deployed form the VC to all hosts that you deploy it to. There is no reliance on the VC for the vDC to work however you should not edit the vDC on each host, it will need the VC to be online to manage it correctly.

The vDS settings are stored on the VC and pushed out to the hosts. You can export a vDS via the Web Client if you need a backup.

So your guest VMs will not be affected when using a vDS during a vCenter crash / outage.
