Problem:
Slow down in performance when Profile Disk VHD’s (non static VHD’s) are on DFS replicated share.
Symptoms:
DFS-R is used to host multiple Profile Disk VHD's of our VDI infrastructure.
Possible Resolution(s):
DFS-R is not recommended for VDH ProfileDisk replication. This is in part due to how DFS-R replication handles changes to VHD. In current form the entire disk get replicated each time versus byte level tracking of changed files. Because of this it could induce a lot of overhead and use large amount of bandwidth between the DFS datacenters.
This will work with ONE WAY replication. It will replicate entire VHD each time the user logs off and the VHD is detached from the system.
