I am working on what will eventually be a large scale document repository. (Tens of millions of docs, mostly PDF.) Obviously I am considering using Document Centers or Records Centers, but I am still a little unclear as to which direction I should go. This is the kind of system where the documents themselves will not be edited or changed at all, the only changes might be changes to metadata values associated with the docs, and that, only on rare occasions. Everything going in is considered to be finalized. So my initial thought was that a Records Center would be appropriate.
Part of the functionality of this system is that, although there will be limited addition of content, there is going to be a lot of search-and-retrieve type use, and I have read conflicting things about whether or not a Records Center is appropriate for that. Can anyone clarify?
Also, I have read various suggestions for content database limits for Records Centers (namely 200GB, 1TB, and 4TB). Which of those limits would be best for a system that will have write once, read many type functionality?
Thanks for any clarification / advice / suggestions!
