Dedicated link between Servers

What is the proper way to create a dedicated link between two (or more) high traffic servers and ensure traffic between them travels that link instead of through the public interface?

Proposed Network Configuration
We have Citrix boxes providing ERP Software to clients which is data intensive, to ensure best performance I would like the traffic between the Citrix Boxes and SQL Box only to travel the dedicated 10G link on its own VLAN.  Clients should be able to access the VLAN3 interface, and those should be the ones DNS resolves to for Clients/Servers but they wouldn't have direct access to the VLAN4.

I can accomplish it with static IP addresses for the VLAN4 interfaces and modify the local host files on each server connected to that VLAN but I was wondering if there was a better way to accomplish what I am trying to do?

Static IP addresses on VLAN4 is a must.  However instead of modifying the host files, I would suggest you either hard code the "VLAN 4 IP address" of the server where needed, or create a new dns entry, say hostname.vlan4.domain.tld, and code the alternative host name.

host files are a mess, even if you only have a few entries in them.

However, are you really driving the 10 Gbps network??  Would it hurt, or cause problem if you just put VLAN3 on the 10 Gbps network and let user traffic and server-to-server traffic flow on it?

The only reason I could see for separating them is if you are driving the 10Gbps network to over 5 Gbps regularly and you were using Jumbo frames.  Otherwise I don't think separating the user traffic from the server traffic is really buying you that much in performance.

Thanks, don't know why I didn't think of the alternate host name dns record - want to avoid using the IP address references wherever possible.  As for if we'll see much advantage over it, I'm just doing what's asked of me!
