Dear god,
I also saw a few tutorials about virtualization, but always don't understand, I hope you can help solve,

I need to implement the functions as follows:
1. Employees can use CTRIX desktop login system, should be based on virtual EXSI
2. Each employee can use the NAS allocate disk space, and can set up mutual access permissions
3. The system can be agreed to deploy software and upgrade function,
4. You can remote login the virtual system of the company,
5. What function need to buy a few servers, these models good

Thank you for your attention
