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