Has anyone tried scaling a VMs io by adding additional disks and striping them in the guest os? I am curious what effect this would have on io performance?
Why would it? You can also change the stripe size of the RBD image. Depending on the workload you might change it from 4MB to something like 1MB or 32MB? That would give you more or less RADOS objects which will also give you a different I/O pattern.
