Is there more detailed design documents?

[Evan (Evan Tschannen)]

Unfortunately, we do not have any additional design documents. I posted some additional details of the architecture in a different thread, but nothing that covers your specific questions.

Technical overview of the database

Just to be pedantically clear: you must lock a set of old tlogs such that it overlaps with any quorum of old tlogs that could be used to commit before starting a new set of tlogs. The new tlogs and old tlogs have no quorum interactions.
