True, you need a P410 controller. You can create RAID0 for each disk to make it as JBOD.

However with these machines if you want to do more than 4 hard drives then HP puts in a P410 raid controller. We would configure the RAID controller to function as JBOD, by simply creating multiple RAID volumes with one disk. Does anyone have experience with this setup? Is it a good idea, or am i introducing a i/o bottleneck? Thanks for your help! Best, Koert
