Dear all
We have two JBODs with 20 or 21 drives available per JBOD hooked up
to a server. We are considering the following setups:

RAIDZ2 made of 4 drives
RAIDZ2 made of 6 drives

The first option "wastes" more disk space but can survive a JBOD failure
whereas the second is more space effective but the system goes down when
a JBOD goes down. Each of the JBOD comes with dual controllers, redundant
fans and power supplies so do I need to be paranoid and use option #1?
Of course it also gives us more IOPs but high end logging devices should take
care of that

Thanks for any hint
