Switching from subnets to VLAN's

Hello all,
Here’s my situation:
I have two networks. They are currently setup as two separate subnets behind a sonicwall.
X0- Subnet A (192.168.1.x)
X3- Subnet B (10.0.60.x)
The sonciwall routes traffic between Subnet A and B.

Here’s my problem:

 I have a new Scale Cluster. This cluster will host virtual servers from both IP ranges, but is physically plugged into 192.168.1.x subnet. If I spin up a server and put it on the 10.0.60.x range it cannot communicate to the either subnet or the internet.

Here’s what I think I know:
My proposed solution is to configure two VLAN’s on the Sonicwall LAN port. The VLAN routing will be done by the Procurve.
This is my first VLAN setup so feel free to shoot holes in my plan (after all, that’s what I’m here for).
I will be using HP Trunk Ports with tagging.
VLAN 10- 192.168.1.x. Subnet A (and Scale Cluster)
VLAN 20- 192.168.120.x. VOIP phone traffic. This is currently run on subnet A along with my data.
VLAN 60- 10.0.60.x. Subnet B and some hosts from Scale Cluster.
Both VLAN’s will communicate with each other and the internet.
I don’t know how to configure these yet, but will work on that once I’m pretty confident I’m on the right track. I have zero experience with HP CLI so it will done using the web interface.


1.      I am using an HP 2920-24 for my primary Switch. This is where I will configure Trunk Ports and VLAN tagging.
2.      Subnet A has a couple different switches. Netgear GS724TP and TPlink SG1024D.
3.      Subnet B is using a Netgear Prosafe JGS524E
I’m cannot seem to find anything conclusive about whether or not the Netgear and TPlink switches can pass VLAN tags. I think at this point I will just have to try and see if it works.
I am working on a production system and am very reluctant to make changes until I am fairly confident I know what I’m doing.
I do have a spare TZ150 that can be used to test my VLAN’s/VPN setup. I have also considered picking up an EOL Procurve  ($100 on eBay) and setting up a test network. Did I mention how much I hate testing on a production network?

I appreciate any input,
