2 node DAG in a single site and Witness Server config?

$

Hi,

I am after some advice on the following setup (all in a single physical site)

Virtual Server Host 1 with the Virtual Server Guests below

  • Server HTCA-01 (Hub Transport and Client Access Role in CAS Array with HTCA-02)
  • Server MBX-01 (Mailbox Server and DAG member)

Virtual Server Host 2 with the Virtual Server Guests below

  • Server HTCA-02 (Hub Transport and Client Access Role in CAS Array with HTCA-01)
  • Server MBX-02 (Mailbox Server and DAG member)

Witness server is HTCA-01 and Alternate Witness is HTCA-02

I am concerned that we have an alternative witness server configured and dont appear to need it? Is leaving this configuration in place a problem? Is there any negative effect?

Also, if I reboot Virtual Server Host 1, I lose both the primary mailbox server (MBX-01) and the witness server (HTCA-01). Will this then mean the database will not failover and mount correctly on MBX-02? Do I need to move the witness server to HTCA-02 and remove the alternate witness server altogether?

Thanks

Paul
