Hi Sean, 
I may be wrong, but I think there is not any "best" RAID strategy when it comes to the disk for the nodes or a "normal" one. All RAID type have their pros and cons.
It'a all about security over performance against total space that would end up usable. What RAID controller is that?

When I have a set of rack servers that is 1TB * 4 disks in each of it as Nova Compute Node, what is the best RAID (or JBOD) strategy OpenStack community recommend? 

Basically I'd like to know what a normal disk setup a compute node should be using.

Thanks,
Sean
