Indeed. Many data-centers have a multi-tiered approach to fire-suppression. This usually includes a chemical suppressant as first line (often a de-oxygenate that suppresses fires by removing oxygen from the room and does not damage servers) as well as a preaction dry-pipe system as a backup (in this case the fire has gone too far to save the severs and the goal is to protect the rest of the building).
