Shared access to the global namespace

A homogeneous environment is one in which all clients run the same operating system. In a homogeneous environment, SAN File System provides access and semantics that are customized for the operating system that is running on the clients. For example, when files are created and accessed from only Windows® clients, all the security features of Windows are available and enforced. When files are created and accessed from only UNIX® clients, all the security features of UNIX are available and enforced.

A heterogeneous environment is one in which clients run more than one type of operating system. In a heterogeneous environment, there is a restricted form of access. For example, when files created on an UNIX client are accessed by a Windows client, access is controlled using only the semantics and permissions of the "other" permission bits in UNIX. Similarly, when files created on a Windows client are accessed on an AIX® client, access is controlled using only the semantics and permissions of the "everyone" group in Windows.
