[Pvfs2-users] Question about redundancy

Hmmm...  Having a failover to shared storage would be OK but would 
involve procuring 80TB of shared storage...  Of course I could use 
node1-100 for filesystem1 and node101-200 for filesystem2 (some kind of 
drbd implementation).  Weighing this against IBM's gpfs, which ain't 
free but they have a bit better redundancy I think...  Any notes on 
performance?  Has anyone tested write speed of say, 3TB or something?
