Hi,

I have 3 esxi servers with 1 vmware virtual center server.
Currently my old servers are the dns server for those esxi servers. But those servers should will be replaced by virtual ones on the esxi server.

How can I handle the dns part?
I have a firewall which is currently running astaro but I want to replace it with clarkconnect. Can this server be the dns server for esxi?

As long as your DNS server is always available, you can use any one. It would be best not to have all your DNS servers in virtual instances. Potentially you could also make your VC server a DNS server if it running on Win2K3 or later. Probably the firewall as it should always be up ...

I think that astaro or clarkconnect always forward the dns queries. Anyone know how to do it specificly for astaro or clarkconnect?

Are you using Local Storage or SAN Storage ?

Do you use DRS, vMotion or HA ?

How is the firewall configured ? Is it a physical Server directly connected to the Router ?

With three ESXi servers I would not hesitate to run the DNS in several of the Virtual servers, I've done that for years and haven had the least bit of trouble from making the descison.

You dont mention your server config, if you are running a domain with AD, then of course your DCs are going to have to have DNS.  Use them!

If your dns are virtual it will work but only when at least 1 dns stays up. In case of a long power outage every server is powered down!
