Thanks for the comment. We do a full scan from another server to our cluster. This AV server will scan all the hard drives attached and is set to skip over the database related files like .MDF, .LDF, etc.

By having this setup, there are no performance hit caused by the AV. If you have your cluster facing the internet for a website then maybe I can see the need. Our servers have been setup so that only the Domain Administrators can connect to the server and/or its drives. All users can only access the data within the databases and nothing more.

Thanks,

Rudy
