Hyper-V virtual networking check

Gents

just checking before I go away and build this (I’ve been a “manager” for the last 3 years and am very out of practice. Can’t remeber the last time I got my hands dirty!).

I have a well spec’d Dell 2900 that we are planning to build a compelte MS virtual infrastructure on. The host is running srv2k8 with Hyper-V. All servers will run on this box and several clients will connect on the physical network to them.

In addition there’s a DSL modem/router that will be connected to a virtual ISA server running on the host.

Given this I think I need the following in terms of virtual networking:

1 external network setup to the NIC that has the DSL line attached

1 external network for connection to the physical LAN for hte clients to be able to connect to the servers

1 private VM network for the ISA to be able to connect to the other VMs.

Does that sound about right? The server currently has 6 NICs so I’ve got plenty of flexibity.

cheers
