Citrix PVS to multiple vlans

Citrix provides basic guidance on how to multi-home your Provisioning Servers (PVS) with CTX120955.  But what if you have multiple vlans for desktops in which you want to stream to?  Well this is how we did it.

Environment
Citrix XenDesktop 5.6.1 
Citrix Provisioning Server 6.1
VMware ESX 4.1 U1
Cisco Nexus 7000

Network/Firewall
A few things to point out.
- All vlans were separated by the firewall.
- Used one PVS farm for all desktop vlans.
- All firewall rules were setup to all outbound access to the DDC.

Citrix Provisioning Services (PVS) Setup
PVS Physical Server Specs
- HP DL380 (dual-core 48G RAM)
- 1G Network Team for management vlan access
- 10G Network Team for desktop vlans
- 2 x 146GB (RAID1) for OS
- 6 x 146G (RAID5) for local vDisk storage


We are using this PVS configuration for XenDesktop so...

• the 1G team is for all PVS, DDC, SQL, AD, etc communication. 
• the 10G team (streaming only) is setup using the HP Network Configuration Utility (NCU) and vlan tagging and has 5 desktop vlans on it. We could just have 1 vlan but each desktop vlan is segmented by a firewall and we don't want to stream through that which is why trunk down all the desktop vlans to the PVS 10G ports and configure with 802.1q so they are directly on the vlan. 

Citrix XenDesktop Setup
Each XenDesktop virtual desktop (VDA) has 1 vnic on a desktop vlan. 

TFTP Setup
There are a few options here but first we
- Had a pair of Citrix TFTP server(s) on each desktop vlan providing TFTP/PXE but...
- are moving to Infoblox TFTP services to provide this so we don't need all those TFTP servers.

It is seems overly complex but is fairly straight forward and best of all meets the requirements for desktop segmentation and allows you to manage only 1 PVS farm.

Interested to hear how you do PVS.
