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 -- john r pierce, recycling bits in santa cruz
