I have the P822.  It has no JBOD or RAID 0.  hpacucli works with CentOS 
7.0, but is broken on 7.1 -- it cannot find the controller.

try hpssacli, thats replaced hpacucli and supports the newer controllers 
on newer OS's.

JetStor, from AC&NC, is a *real* nice solid line of RAID appliances... and
esp. when you get to the bigger ones, runs half or a third the price that
NetApp, HP, or Dell RAID boxes run, literally. Really reliable hardware -
we've got some that have been running for well over six years with no
troubles (other than an occasional dead drive). (No, I'm not getting any
kickbacks from them - I really like their hardware.)

Can it do RAID 6?

This page says it does.

The page also says it does RAID 0, but I did not see that in the 5.42 BIOS.
