Netapp filers are wonderful.  The ability to have a fast redundant file 
system that can periodically take snapshots of your data is a very good 
thing to have, especially in industries where you may be called upon to 
"roll back" your data to specific points in time on demand.  They are 
also extraordinarily expensive.  Same goes for EMC solutions.  They are 
both doing very well on Wall Street applications these days and that's 
where I typically run into them.  And in those environments, their cost 
is more or less statistical noise in the overall IT budget.  For your 
typical small business or even mid-size business they're overkill and 
overpriced.  For myself and on a few consulting gigs, NFS and samba have 
served me well, depending on the application, running on vanilla 
RHEL/CentOS systems with a pile of SATA disks hanging off 3Ware cards.
