Do you have the Dump Collector Service installed, this is where core dumps are stored.

So answering your questions, these ESXi core dumps, and yes they can be deleted, or archived if you need to refer to them later.

I do not have dump collector installed that I know of...

Are these dump files crashes from my vCenter server or host?

Hi,
in case you need to configure it differently :

and more information :

Also you should better use vCSA (vcenter linux appliance) rather than Windows vCenter, as it will be removed soon in next releases.
