Hi all, I am planning to add block storage (iSCSI) to my oVirt environment. I just stumbled across this point from the oVirt Documentation: "6. Select an active host in the Use Host field. If this is not the first data domain in a data center, you must select the data center's SPM host. Important: All communication to the storage domain is through the selected host and not directly from the oVirt Engine." (you find it here: https://www.ovirt.org/documentation/admin-guide/chap-Storage.html#adding-block-storage)
So my question is: Is there a significant performance advantage for VMs using the storage that are running on that "selected host"? Because if this is the case, I would connect all my host machines to the dedicated storage network, create multiple data domains and "split" my iSCSI storage server(s) among those domains. If it is not the case, I would only have my storage server(s) and one of my hosts in the storage network. This also has implications on the dimensions (and cost!) of the switch that I use for the storage network, so I would be grateful if someone has any insight.
