Hm, I'm talking about both: My file server (about 10TiByte RAID) and...

Roughly the same numbers here - and that's the CentOS boxen only, not to
mention xBSD, Solaris, and AIX machines.
IMHO one of the main reasons for running (Open)Solaris for most people
(read: those w/o having to run Solaris due to historical reasons) do so
because of ZFS.
XFS has different feature sets, strenghts and weaknesses, but the advantage
of both XFS and ZFS is their total lack of fsck hassles, compared to extN.

So, where's exactly the connection to underlying file systems?

One of my most favorite jokes is to begin IT related discussions with 'in
an ideal world'... ;)
