This was of no problem as it was only a slight modified Gladius Frigate. Modified to the degree that it in fact had more weapons and less quarters. While it was common to have multiple hundred if not even thousands of serfs and up to a squad of Space Marines on such ship, this modified frigate was improved due to using Servitors instead of Serfs. Saving space that would be required for quarters, canteens, storage for food and water, etc. Making the ship ultimately far more effective in combat, as long as boarding could be avoided.
