[Beowulf] urgent: cost of fire suppression?

[Stu Midgley]

Yes, live in Australia, but in Houston at the moment (installing a new
system).

I don't disagree that they aren't good and indeed the removal from the
market has led to lots of other technologies.  As indicated earlier, our
next room will use this

http://www.victaulic.com/en/businesses-solutions/solutions/hybrid-fire-suppression-technology/

which looks pretty cool and doesn't need a pressure rated room.  Which,
makes it much easier to get fibre/cables out of the room.
