Which cinder drivers support QoS ?

Below link contains the list of drivers for the cinder-volume service.

Ciner-Volume drivers list

I was wondering which of those vendors supports QoS options such below?

  • total_bytes_sec: the total allowed bandwidth for the guest per second
  • read_bytes_sec: sequential read limitation
  • write_bytes_sec: sequential write limitation
  • total_iops_sec: the total allowed IOPS for the guest per second
  • read_iops_sec: random read limitation
  • write_iops_sec: random write limitation

Based on below links, I believe CEPH and SolidFire do support QoS, but I am not sure about the other vendors.
