How much disk space is required for an RTC 4 database?
There doesn't appear to be any documentation as to how much space one should allow for when planning a deployment. There's not even a rundown of the space efficiency of various different operations (i.e. presumably creating a new baseline doesn't copy the source code, and presumably changesets are stored as diffs, but who knows?).
I would expect this type of thing to be discussed in the CLM 2012 Sizing Guide but that only mentions how many of each artifact RTC supports.
So, how much disk space might be required for (say) a gig of source code with 100 changesets a day with each averaging 100 LoC changed/added/deleted, 500 baselines and 50,000 work items (with say a 100kb attachment on 10% of them)? A great answer would explain how each of these items affect the space requirements.
(Clearly we can do some naive back of the envelope calculations - e.g. in this example, 500mb worth of screenshots, 5 gigs worth of work items if they are 10kb each, etc, but this doesn't take into account any deduplication, and it seems potentially dangerous to make assumptions along those lines)
