Depends a little bit what your expected work-load will be but again generally you want to aim for one logical core per OSD - so 14 core CPU in your case, 16 wouldn't hurt. Ceph tends to eat heavily into resources (RAM and/or CPU) when it needs to recover from a problem which are the situations when you really don't want to have to deal with under-resourced hardware.
