Fire suppression

It doesn’t matter how secure your server is if it’s on fire. The other Scoble has two good posts that describe the current state of the art in fire-suppression systems: here and here. This is actually something I talk about in Chapter 5 (physical &operational security), even though most of us are stuck with whatever physical plant is already in the building. Interestingly, one commenter mentioned pre-action sprinkler systems, which use water but which aren’t activated without both heat and smoke alarms. (And hey, the inert suppression gas of choice is Inergen, not “Innergen”.)
