Thanks for your inquiry. I am the Services Director for Datawatch so can answer this with some authority and experience.
RMS is Windows Server Based.
Your ICN is non Windows based.
ICN uses a plugin that leverages the RMS API. It basically says;
- take report(s) X,
- select model(s) Y
- and render an RMS session with X function(s) enabled
The reports are extracted from the host content management system and placed in a location where the RMS session can access the same to facilitate the user experience.
As you are using the above mix of OS's, we need a way to allow this common storage visible to both. This is done using the CIFS mount. Generally, this is done using an SMB share, but some customers do not allow this per their internal security policy. Where SMB is not allowed, CIFS seems to be the acceptable compromise.
Even in a pure Windows environment with both RMS and ICN using MS Server versions, we still have this share but as the OS's are common, we just have a simple windows share (either UNC or local, depending on single or multi server).
The next version of RMS will actually have an enhancement to forego the share, this is due in the next few months. The intention is to flatten / simplify the deployment requirements; in this case, removing the share between the Plugin and RMS.
So for now, the only option is the use of a CIFS or SMB share.
