[ovirt-devel] Re: [ovirt-users] oVirt HCI point-to-point interconnection

The final purpose is strictly targeted to your HCI solution with 3-node gluster replication.

Initially with the idea of optimizing the direct communications between the nodes and especially the gluster communications, and so it would seem quite easy, then evaluating a more complex configuration, assuming to create an overlay L2 network on the three L3 point-to-point, using techniques like geneve, of which at the moment I have no mastery. If the direct routing of three nodes to interconnect the public network with the private overlay network was not easily doable, we could leave the private overlay network isolated from the outside world and connect the VM hosted engine directly to the two networks with two adapters. This layout with direct interconnection of the nodes without switches and a shared L2 overlay network between the nodes may in future be contemplated in future releases of your HCI solution? Thank you for your attention, have a nice day! Stefano Zappa. [cid:609f1f14-f74e-489f-b86d-08647efc6d1c] Stefano Zappa IT Specialist CAE - TT-3 Industrie Saleri Italo S.p.A.
