Summary 

 
Please review the topology check list and diagrams to configure your U170 multi-user 
environment so it will work optimally.  Once done the results from these 5 and 10 users scenario 
demonstrates that our U170 product can provide excellent performance for each U170 user on 
NComputing’s virtual desktops. We demonstrated that a host PC can power up to 10-users 
simultaneously while executing productivity, office and multimedia applications with plenty of 
CPU and memory resources to spare.   
 
These environments demonstrate how NComputing vSpace desktop virtualization technology 
can utilizes excess PC computing capacity and distribute it to many users.
