No LVM and the RAID is done in the SAN appliance.
My gut tells me that formatting a single huge 25TB partition is not the 
best way to go. That's why I consider having two different LUN's on two 
different SAN's mounted together as two directories. A fsck and a 
recovery will work faster.
The only issue is distributing maildirs. across the two file systems.
