As I said a bit further down in my previous e-mail: you can use GPFS, CXFS, 
GFS as its filesystem and have redundant hardware.

If you want to get a better idea, check out SONAS from IBM. It's basically 
GPFS + Samba and redundant HW. You get HA, high performance, modularity and 
flexibility. You can also check out:

If you don't want to shell out what IBM is going to charge you, you can DIY 
(if you have the knowledge) or you can hire some Linux consultant that has a 
good Linux knowledge.
