Each RDB device has some inherent IO limitations, but using multiple in parallel works quite well. We never were able to use fancy striping for this purpose, but LVM is simple, well tested, and does not require any extra considerations. We currently just use spanned volumes, not striped (although this would be interesting), and allow parallelization to take place via database itself - the parallel IOs are not necessarily aligned on RBD boundaries, but for our purposes, and using all SSD OSDs this is enough.
