[ovirt-users] IOPS stats/reports from all hosts to storage

[Neil]

Hi Karli,

I was hoping that too, but it seems the SAN doesn't have these features.

There is only the 4 oVirt hosts connected to it via 8GB FC.

I see oVirt has Storage QOS, but how do we set Storage QOS without knowing
the maximum storage limits? Perhaps I'm misunderstood this...

Thanks.

Regards.

Neil Wilson.
