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

http://docs.openstack.org/juno/config-reference/content/section_volume-drivers.html (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.

I checked every vendor website who contributed driver to Cinder and below is the conclusion.

Upon OpenStack Mitaka release

34 companies integrated their storage solutions with Cinder
57 drivers are contributed to Cinder
- Only 10 drivers from 8 companies support QoS
- EMC | Hitachi | HPE | Huawei | IBM |NetApp | Violin Memory | X-IO technologies
