Do both. Host striping will give you more queues, RBD striping will use
more OSDs.

Because you only assigned 1 volume (sdb), you will be limited to a
single queue. I'd recommend adding more volumes and striping the data
across.
Is adding more volumes, and stiping them in OS, better then using the
RBD fancy striping options ?
