We're trying to configure our RD Session Collection to use a CIFS share from our EMC VNX to store the User Profile Disks. However, we're running into an RPC error when trying to create it. After searching here a lot of posts seem to conclude that it can't be done with a non-Windows file server solution (even though this VNX definitely supports SMB 3.0, and is configured to use SMB 3.0). What I don't get is why this MS article mentions "User profile disks can be stored on Server Message Block (SMB) shares, cluster shared volumes, SANs, or local storage."if it really can't be done by using a SAN in the logical way you normally would with a VMware environment: http://blogs.msdn.com/b/rds/archive/2012/11/13/easier-user-data-management-with-user-profile-disks-in-windows-server-2012.aspx
This forum post pretty much says the same thing about not being able to use an EMC VNX: https://social.technet.microsoft.com/Forums/en-US/8bf3ac9a-46a6-41de-b834-fb9832e1e8b0/user-profile-disk-on-emc-vnx-storage?forum=winserverTS One person in that thread mentions using a Windows scale-out file server cluster in VMware vCenter (I'm guessing using a SAN/NAS as the back-end). Is this really the only recourse we have if you want highly available UPD while still using your NAS?
