Thank you both for some brilliant suggestions... I am new to the world of Citrix need a bit of hand holding in terms of the software..

From what I understand from your posts is.

Hardware
-------------
- 12 x Physical Servers each with Max Mem, 2 x Quad CPUs, 2 x 72GB Raid1 Disks, 6 network ports
- 2 x SAN
- Switches


Software
------------
- 12 x Xen Server Enterprise Edition
- How many XenApp Licenses?
- How many XenDesktop License?
- How many Windows Server Licenses?
- How many Windows Server RDS CALs?

Its software I am confused about.. Can you guys please help me in compiling the list and number of software require desktop vdi usin citrix
RDS Cals = # of users in your environment.
Windows Server Licenses = RDS CALs unless you are using machine CALs and not user CALs
Get Xenapp licenses because it is concurrent usage9unless they changed this)  By doing this you only need to purchase a percentage of your user base un less every user works remotely 100% of the time.

We have 1200 users with maximum of 500 concurrent connections.  We want to allow users to acccess the new Windows 7 as a virtualised desktop therefore, do we need 500 x Windows 7 Pro licenses?  Would we still need RDS CALs? I guess not and rather need server user CALs?
If you go with XenDesktop 5 only you will not need RDS CALs.  If you plan to use XenApp as well you'll need RDS CALs.

Pardon my ignorance.. is XenDesktop a one of license or is relevant to concurrent desktops?

After a lot of research I have come to the conclusion that we need to buy the following to accomplish the VDI side of things..  Can someone please confirm this:

- 10 x XenServer Enterprise Edition + 2 for failover
- 500 x XenDesktop Device Licenses (Allowing all users to logon via any device)

Please correct me if I need to purchase anything extra..


Many Thanks
Your XenDesktop licenses should come with XenServer licenses as well.

You will also need OS licenses for your servers.

Yes I am aware of the Windows OS Licenses..

Does each XenServer license comes with x no of XenDesktop licenses? If yes then how many XenDesktop Licenses come with each XenServer License?

Also am trying to look for a dell SAN.. can someone give me an idea on how much space do I need to provision to host 500 simultaneous desktops? I would like to allocate 30GB per desktop for the OS and software installation files therefore, does this mean it's 30GB x 500?  Which is way too much space requirement..  

All user data will be stored on a separate SAN..
I think the bottom to many of your questions, while we can provide answers are to your benefit to hire a local consultant in your area.  It will be well worth the investment.

ALSO BE CAREFUL with the windows licensing.  When virtualizing desktops, there is also an annual desktop license fee that HAS to be paid PER Virtualized desktop.

Here is a post of some requirements for provisioning: http://forums.citrix.com/thread.jspa?messageID=736118
The number of XenDeskto licenses aren't tied to XenServer licenses.  You can run as many VMs as your hardware will allow on XenServer.  

If you are using Provisioning Services with a Standard vDisk then you only need a single Golden Image large enough to hold the OS and applications.  Of course you'll want some space for backups of that image.  You'll also need some space to store the Write Cache.  

Nappy d is on target with the consultant suggestion.  You are getting in to design questions that are best answered with the engagement of a consultant.  There really is quite a bit to consider.
