Hi, I'm wondering how Ceph behaves when there are multiple sources writing heavily to the same pool (e.g. Openstack nova compute) Will each get its own "fair share" or will a very heavy user impact all others? Are there ways to tune this? (Openstack Havana has added QoS so this somewhat reduces any need to do this in Ceph but I am curious what Ceph does) I guess it is pretty tricky to handle since load can either be raw bandwith or number of IOPS.
