When it's system managed, it's set to a default to the amount of RAM when RAM exceeds 1GB, (1.5xRAM if less than 1GB) but can be up to 3 times the amount of RAM. System managed grows dynamically. SBS-E I wouldn't be surprised if it was just 16. My SBS Standard actually went to 24GB. It can even end up being 48GB if necessary.
