A couple of things to add,

All good server rooms or datacenters must have a reliable air-conditioning system to keep temperatures under control.  
A server room with a lot of boxes can generate a tremendous amount of heat.  Keeping the server room cool will decrease 
component failure (items like hard drives tend to die early if overheated) and will also decrease the chance of 
creating a fire due to excessive system temperature.  I have actually seen a power supply smoke and melt in a very 
large IBM mainframe  when the air-conditioning broke and the room's temperature spiked.

If there is not an operations staff 24X7, you should also have a reliable monitoring system that can page you.  Various 
systems can be setup to page you in the event of temperature increase, fire suppression system release, etc.

Make sure you have your power lines inspected and that you don't overload them or your UPS.  

In my humble opinion, fire prevention should be the first step when considering fire suppression.  But of course, you 
still have to have fire suppression in case one does break out.

From a recent seminar, here are the issues:
    Fire Detection
    Fire Suppression
    Computer Room Policies
    Sprinkler Systems
    Halon Phase Out
    Alternatives to Halon
    Consult an Engineer

Detection under raised floors, consider air sampling systems, can help
prevent discharge.  Pre action sprinkler systems.  Halon grandfathered, can
still re-charge too but no new agent manufactured. Halon alternatives:
inergen, FM-200, FE-13,
Policies oriented on prevention, storing materials in computer room.  Good
carbon dioxide extinguishers.  Computer room standards.

Security includes maintaining availability, right? So I guess that includes
preventing and recovering from disasters. Can anyone suggest a good resource
for information about fire suppression in server rooms, etc?
