<p>It's not the first time this has happened at GSU. It's caused by
the very loud noise that is generated when the inergen gas is
released. It causes errors on spinning disks that quickly fill up
their spare sector table while trying to write during the
discharge. It usually only effects servers beneath the nozels so
that's likely why it only effected tabcorp. </p>
<p>It happend in the AAPT suite on level 4 a few years back when a
belt on an air handling unit failed and smoked up setting off the
fire system. I remember being there and looking into the face of
many broken men on that day. RAID does not help when all your
disks die at once. <br>
</p>
<p>I have equipment in level 2 4 and 6 at GSU and did not hear about
the 7 November incident so perhaps it was just one private suite.

I came across this article, relating to the Tabcorp outage on 7
November - claims the fire suppression system in the hall at
Global Switch was activated and damaged servers, which is why
Tabcorp was offline for so long. GS also claims that Tabcorp was
the only affected customer. Did anyone receive a fire alarm
activation alert?

</div>
<div>What potentially would have triggered the activation and
discharge? <br>
