Dedicated subnet for GIS servers still a best practice?

We've recently migrated our AGS and ArcSDE servers to VMWare and are looking at upgrading to 10.1 in the next few months.  The GIS servers have their own subnet, which was configured by a network admin who no longer works here.  We have a new network admin who has suggested moving the new 10.1 GIS servers to the same subnet where the other non-GIS servers reside. 

I would like to keep the GIS servers in a dedicated subnet.  I've searched for whitepapers or other documentation on the subject but haven't found much.  Is there any definitive documentation or whitepaper that covers the topic?  Is a dedicated subnet still a best practice?
