Neither will eliminate servers and disks as single points of failiure.

If want one filesystem overy many disks on many servers and the ability to 
fail a disk-volume (raid or whatever) or an entire server and still have a 
usable fs then you need something like GPFS with replication enabled. Either 
way, not a trivial config nor trivial software (GPFS for example will cost 
you $$$ unless you're academic).

good luck,
 Peter
