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.

  • http://ceph.com/planet/openstack-ceph-rbd-and-qos/ (CEPH)
  • http://www.solidfire.com/blog/the-architectural-comparison-series-what-has-your-openstack-cinder-driver-done-for-you-lately/ (Solid Fire)

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
