citrix vdi in a box

Hello i will be setting up "citrix vdi in a box" on Microsoft 2012 Hyper-V Server for 20 users.

i have few questions that need clarification as i am not able to test it out on the server yet.

Questions:

1.      Do you create a windows image before installing VDI in a Box or after (will be using Win 7 image) ?
2.      How easy or difficult to adjust the image once it has been created.
3.      If you have limited licenses ie Adobe Acrobat (Full) version and only few licenses. How do you deal with that.
4.      In future if I have a add another Hyper-V server how do I load balance, or move the existing machines to the new server
5.      Can I move the storage location of the Vdisk to let’s say NAS in future. How easy/difficult would that be. Is it simply the case of pointing the Vdisk location to the NAS
6.      Is 10/100 network sufficient for the 20 users.
7. Any Caveats or Gotchas that i should be aware of prior or during  the installation. (lessons learned)

thanks in advance

in fact, you should be able to leverage on the faq for the queries. Note kaviza is acquired by citrix which form the vdi-in-the box
http://support.citrix.com/article/CTX129873
http://kaviza.wikidot.com/faq:index

Below are inputs which I refers to the Faq as well for easier kickstart

1. Use of Desktop template and it covers WIn7
2. You can set up multiple templates and images and you can assign multiple templates to a user. there is Persistent Desktops and Non-Persistent Desktops whereby the difference is the policy refresh for former is manually trigger
3. VDI-in-the-box is licensed per concurrent user desktop. Probably you can estimate s/w licence based on max concurrent user at any one time
4. Multiple servers can be linked together to automatically provide high availability. It handles all the connection brokering and load management across the grid and automatically handles failover in case of server failures. Also all the images, templates, and configuration data are backed up by VDI-in-a-box across the servers in the grid. The recommended best practice is to store user data on a networked filer

Also this setup using the h/w and s/w is useful guideline for the real setup tested.

5. Note that for VDI-in-a-box, you can provide the commodity server such as a Dell 2970, HP DL360 or an IBM X-series server with direct attached storage, and grab also hypervisor such as ESXi or Xenserver and download the VDI virtual appliance to load into hypervisor for the start of desktop creation. So the hardware belong to you. Also you can be migrating from VDI-in-a-Box to XenDesktop. NAS implies shared storage. VDI-in-a-Box does not support shared storage.

In fact for (4) and (5), this one good link to clarify
if you do happen to have a SAN, you could attach a unique LUN to each server in your ViaB grid, and, provided you’re using Hyper-V or VMware as the underlying hypervisor, use that LUN for storing your master images and PVDs. ...Then you could conceivably move that LUN to a different server in your grid in the event of a server failure, and have all your PVDs back…although you still need to do periodic backups of the PVDs (maybe with SAN snapshots?), because it is possible that a PVD could get corrupted if the ViaB host goes down while the desktop OS is in the process of writing to the PVD.

6. really do not suggest just 10/100 but a good sizer guide is below. Most of it is based on  1 Gb Ethernet ports which supposed to support minimal 75to 600  users as estimate range (of course other resource will sized accordinly too)

https://www.packtpub.com/books/content/designing-sizing-building-and-configuring-citrix-vdi-box

7. I look at it more from redundancy, backup and due diligence patch constantly in even of outage. Solutioning wise, there is just no perfect all in one for all type of use scenario and best to segregate desktop template and actual sysm mgmt configuration and store in different h/w. be aware of the type of desktop like persistent and non persistent as manual resource and reminder has to be catered. Also Citrix recommends that you always configure certain optional Profile management settings: active write back and profile streaming.
