CIFS overlapping open optimization denies multi-user access
2. On the client-side SteelHead, choose Optimization: CIFS (SMB1) to display the CIFS (SMB1) page.

3. Under Overlapping Open Optimization (Advanced), complete the configuration as described in this
table.
Control Description
Enable Overlapping Open
Optimization Enables overlapping opens to obtain better performance with applications
that perform multiple opens on the same file: for example, CAD applications.
By default, this setting is disabled.
Enable this setting on the client-side SteelHead.
With overlapping opens enabled, the SteelHead optimizes data where
exclusive access is available (when locks are granted). When an oplock is not
available, the SteelHead doesn’t perform application-level latency
optimizations but still performs SDR and compression on the data as well as
TCP optimizations.
If a remote user opens a file that is optimized using the overlapping opens
feature and a second user opens the same file, they might receive an error
message if it doesn’t go through a SteelHead: for example, certain
applications that are sent over the LAN. If this occurs, you should disable
overlapping opens for such applications.
Use the radio buttons to set either an include list or exclude list of file types
subject to overlapping opens optimization.
