Experts,
I have a some questions, hope someone can help me. One comment before I start, I am not a systems person but I am the one that pays for it and I like to know what I´m buying (so please forgive me if I make some mistakes on terminology or concepts). We will start migrating our infrastructure to VDIs (zero terminals). One consultant wishes to use Linux to get rid of Windows to reduce cost but I´m not so sure it will be so, because of open source consulting costs, but I need to know if Windows will cover everything we need.
1. I´m about to buy 2 servers with 2 processors to have them clustered for availability, we will have 2 VMs with critical applications. How Many licenses do I need to support this? my answer is 2 because each license cover 1 physical server with 2 processors, right? 2012 or 2012 R2 and why?
2. We want to attach a storage solution to better protect our data, I read that WS2012R2 doesn´t support NAS under a cluster scenario, why? then what should I use a DAS or a SAN? and why?
3. We have 'n' number of users connecting local and remote using zero terminals, how many and what kind of CALs do we need? and what will happen if one server fails do I need 'n' CALs in each server or can I make a pool of CALs (license server) that work in the cluster environment no matter wich node is up?
Thank you very much for any help you can povide me with.
