• Fast Track is only for data warehouses. OLTP loads vary so widely.

    It's still hard to guess your load. Maybe Lynn is closed on memory, but 1GB a day/150 databases, isn't a lot. That's like 7MB a day/db, correct? Not a lot of writes.

    Depending on the batches, transactions, etc., you could have lots of variation on what you need. I'd also consider DR here, since I'm assuming having 150 dbs crash would be bad. I might even lean towards a 3 or 4 node cluster if you can do that, or even 3-4 servers (2 primary, 1-2 backup) with mirroring.
