NetApps SecureShare provides Mandatory Share Mode (open mode) locking for concurrent access with PC-NFS and UNIX/NFS. CIFS/9000 provides this locking feature at the HP-UX September 2001 Application Release.

NetApps SecureShare provides byte range locking interoperability even for UNIX/NFS processes that do not participate in the advisory locking protocol. CIFS/9000 has a planned enhancement scheduled to provide the same locking feature. Please read Chapter 3 and Appendix B to understand the actual significance of this capability.

NetApps SecureShare provides Oplock support for Windows clients with concurrent access from PC-NFS and UNIX/NFS. SecureShare will send an Oplock break to a Windows client when a PC-NFS client performs an open on the file, and when a UNIX/NFS client reads or writes to a file. CIFS/9000 has a planned enhancement scheduled to provide the same locking feature.

Empirical data will be added when test equipment becomes available.
