Document/attachment storage in CRM 7 ehp3: which technologie to use?

Hi,

We're setting up a new CRM 7 ehp3 system and are looking into using the "upload attachment" functionality on various objectss. Currently we have an ECC back-end system which uses ArchiveLink for attachments. We also have OpenText in our system landscape.

Furthermore, we'll also be using ERMS (incoming & outgoing).

We're can I find some information on the standard CRM way of storing attachments & documents? Should we be using ArchiveLink, DMS, OpenText integration or even somthing else?

I'd appreciate useful pointers to documentation or guidelines, or answers!

Regards and thanks!
