FastBack POC Help request from some one new to Fastback

Hello to all of you in the Fastback forum.

I have quite a bit of experience with other TSM products but NO Fastback.
I have an opportunity with a perspective customer for a very large project.
This customer is starting from scratch with all new hardware and TSM Software.
The customer wants to stay with windows type servers rather than AIX or linux.
I have begun to read the fastback user's and install guide and the TSM fastback integration guide.
The release of fastback will be the most recent and the TSM server will be at 6.3.3 or 6.4

I have suggested to the customer to do a POC before going full scale on the project.

My questions begin:
can I use vmware guest for a test fastback client
can I use a vmware guest for a test fastback server
can I use a vmware guest for a test fastback DR server
will I have any problems testing this in a environment where all of these guests are in the same data center location.

I will use physical hardware for the TSM server connected to a TS3500 LTO Library.

I would very much appreciate any help you can provide me. I'm sure this will only be the start of many questions I
will have.

Best Regards,
Bob...
