Hi guys, I'm running FC storage with 4 hosts on oVirt 3.6 and we've been having some IOPS issues recently and the SAN provider has asked me to provide them with the following info... Datastore Stripe Size Default VM Disk Stripe Size Average IO Size Average THROUGHPUT (MB/s) Average IOPS Maximum IOPS Read/Write Percentage of IO Datastore Average Latency VM Disk Average Latency All of this is from across all hosts and VM's to the storage domain. Is there any way to get this kind of info from oVirt? I've been looking at oVirt-reports but I don't see much as far as IO/throughput reporting goes. Apologies if I've missed something obvious.

Thanks. Regards. Neil Wilson. _______________________________________________ Users mailing list Users(a)ovirt.org http://lists.ovirt.org/mailman/listinfo/users

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.

Haha it is rather crappy. It was very cheap in comparison to Dell's and HP's etc at the time, and it's over 6 years old now so it's done quite well considering the price. The brand is Cipherwave which I think is a rebrand of some other brand, very basic GUI and features. So is there no way to get data domain IOPS from the oVirt side?

Thanks!
