OneDrive / OneDrive for Business using DEM and FSLogix Office Profiles

Greetings Community.  Has anyone implemented OneDrive and/or OneDrive for Business along with VMWare Dynamic Environment Manager and FSLogix Office Profiles?  In a non-persistent VDI Scenario we are using DEM to manage the user side of our profiles, and the FSLogix Office Profiles to manage the Office side. 

A few questions:

• Data center/building cache - is there a mechanism for building-level cache, or does every user have to long-line back to Azure every time?
• Non-persistence –
  • Does the OneDrive Sync Cache save to the FSLogix Office Profile container?
  • Does it cache on logon or upon accessing a file and the purge the cache on log off or does it persist in FSLogix?
  • What are the minimum and recommended storage requirements for FSLogix for OneDrive?

Any tips and tricks would be greatly appreciated.  

Thank you!
