  Not necessarily.  People commonly use NetApp filers in this case.  And
clustering is a standard NetApp feature.  Without clustering, NetApp
claims 99.9% availability.  With clustering, 99.99%.

  NetApp has a lot of integrity and availability checks.  It is the only
system I've seen that that does RAID scrubbing.
