Hi,

A more recent document to refer to would be the NAS support matrix, available on eLab navigator.

https://elabnavigator.emc.com/emcpubs/elab/esm/pdf/EMC_NAS.pdf

On page 77 of the above guide (March 2007 version), would be the compatibility table of CAVA vs NAS code vs Antivirus software versions.

As to an explaination of what has happened to the original NAS Support Matrix:
