You should configure multiple virus scan engines to enhance performance and high-availability of the server.
You may select between the legacy RPC protocol or the newer ICAP when setting up new virus scan engines.
After installation and configuration has been completed, the virus scan engine will automatically self-register with the server.
Compatibility with SMB3 Multichannel
If the virus scanner server has multiple network interface cards (NICs) installed, some virus scan engines cannot use SMB3 Multichannel with the NAS server. Check with your NAS server provider for information about compatible virus scan engines when using multiple NICs.
