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.
Can it do RAID 6?
This page says it does. http://www8.hp.com/h20195/v2/GetHTML.aspx?docname=c04111199
The page also says it does RAID 0, but I did not see that in the 5.42 BIOS.
on many of those P4/P8 series raid cards, raid6 support is an extra cost option, but once its enabled for a given card, it continues to work on that card even if its moved. The P420's I have support raid0 (stripe)...
I googled JetStor, and saw a whole lineup of NAS/SAN boxes that support NFS, ISCSI, etc. these wouldn't work with a raid card like a P800, but a SAS expansion tray from a JetStor should work if direct connected to the SmartArray card... a JetStor that has its own embedded raid controller with SAS host connectivity won't work with a hardware raid card like a P800, you would instead want a simple HBA card, such as a HP H221 Host Bus Adapter
