  OK, a quick search shows the 2311 was indeed
hydraulic!  
 The University of Missouri, Rolla 9 drive 2314 was
 hydraulic, and on night a drive's actuator unloaded into
 the pack area, and took it out, but the damage from that
 major failure was contained w/o the pack or actuators
 exiting the enclosure.  however the debris took out all
 the packs and drives.
 
This one wasn't when I was there.  I think we also had a oil
spraying event there, but it was relatively contained.  We
had one at Washington University, also that might have
contaminated several spindles before they got all the packs
unloaded.
I think this one is fairly quickly detected if the computer
room is occupied, it causes a strong oily smell that is
quickly spread by the A/C system.
