You must follow certain guidelines when you create a shared folder to use as a profile repository.
If you use Windows 8 desktops and your network share uses a OneFS file system on an EMC Isilon NAS device, the OneFS file system must be version 188.8.131.52 or later.
You can create the shared folder on a server, a network-attached storage (NAS) device, or a network server.
The shared folder does not have to be in the same domain as Horizon Connection Server.
The shared folder must be in the same Active Directory forest as the users who store profiles in the shared folder.
You must use a shared drive that is large enough to store the user profile information for your users. To support a large Horizon deployment, you can configure separate repositories for different desktop pools.
If users are entitled to more than one pool, the pools that share users must be configured with the same profile repository. If you entitle a user to two pools with two different profile repositories, the user cannot access the same version of the profile from desktops in each pool.
You must create the full profile path under which the user profile folders will be created. If part of the path does not exist, Windows creates the missing folders when the first user logs in and assigns the user's security restrictions to those folders. Windows assigns the same security restrictions to every folder it creates under that path.
For example, for user1 you might configure the Horizon Persona Management path \\server\VPRepository\profiles\user1. If you create the network share \\server\VPRepository, and the profiles folder does not exist, Windows creates the path \profiles\user1 when user1 logs in. Windows restricts access to the \profiles\user1 folders to the user1 account. If another user logs in with a profile path in \\server\VPRepository\profiles, the second user cannot access the repository and the user's profile fails to be replicated.
