Hi everyone I hope you are all well and can assist.
Im calling on you nice people to offer your guys' experience when determining what things to consider in implementing a VDI solution for your company. Currently, we are in the process of selecting a vendor to offer a VDI solution, and Id love some feedback from your guys experience about what are the most important things to consider when selecting a vendor for this piece of work.
So basically, what im after is:
1.What do you guys deem as really important to consider about what you expect from a vendor and how they implement your VDI?
2.What are the things that you currently see as problems that could have been addressed sooner eg.at implementation phase of your VDI rollout, that people should consider when selecting a vendor?
Any help greatly appreciated.

To get you started:

Citrix has always had the best reviews, and it really is the best and most feature-rich solution, IMO.  Good performance, best storage usage, good manageability.  Really important for me is innovation, and Citrix really shines in that area.

Most problems center around I/O.  Make sure your write cache for your provisioned desktops is properly configured, and make sure you have enough bandwidth to storage for your users to have a pleasant experience.  Make sure you distribute your storage as well.  Highly recommend you have a look at the evaluation virtual appliances from Citrix.  They will help immensely in setting up a proof-of-concept.

View running on ESX will kill you on storage requirements.  Thin provision your desktops with Citrix Provisioning Server.

Hi Toxic, thanks so much for you help on this.

When you talk about I/O, Im not sure exactly what you mean, but would be keen to understand this.
Commented:
I/O = Input/Output = Disk activity (in this case)

Your single biggest problem is storage performance on a large deployment.  Capacity is easy to overcome, but performance and bandwidth to the storage are less so.  That why you distribute your storage.  The general accepted limit is about 10,000 desktops attached to a single farm/array (YMMV).  Past that, grow your infrastructure linearly with new farms and new storage.

I would not use Thin Provisioning for a VDI desktop deployment.  If you have thousands of desktops with their own LUN, your I/O will hit rock bottom.  You will benefit the best from using Thick Provisioning.  You can create a giant LUN with multiple LVHD Logical Volumes (Thick).  Now for  servers, I would highly recommend Thin Provisioning.
