Hardware wise - try one server with CentOS Stream 8 and check that all hardware is recognized and works as expected.<div><br></div><div>You can start with a single server and expand further. RH dropped Gluster Support for their downstream solution (RHV) , yet oVirt doesn't have plans to get rid of it.</div><div><br></div><div>The easiest for you would be to use SAN or NAS as storage. If that's not an option, you can use GlusterFS - which is a distributed File System . The latter needs a 10GBE NICs (1 Gigabit is OK, but don't expect much speed when writing in the VMs).</div><div><br></div><div>oVirt supports GlusterFS in 2 modes:</div><div>- replica 1 - a mode intended for a single host setup</div><div>- replica 3 (where you have 3 copies of your data) - where the storage nodes should be multiple to 3. You can also have compute-only oVirt nodes (those do not participate in GlusterFS but have CPU &amp; RAM to host VMs)</div><div><br></div><div>If you configure HA VMs , the engine will take care to recover them on another host. If you loose 2 out of 3 servers - GlusterFS will loose majority of the bricks (term for a host+mount point combination) and will shutdown until majority is restored.</div><div><br></div><div>In all cases - you should segregate the network for Storage and Compute workloads (Gluster/NFS on separate network).</div><div><br></div><div><br></div><div>P.S.: iSCSI is also a storage&nbsp; option.</div><div><br></div><div>Best Regards,</div><div>Strahil Nikolov&nbsp;<br> <br> <blockquote style="margin: 0 0 20px 0;"> <div style="font-family:Roboto, sans-serif; color:#6D00F6;"> <div>On Fri, Sep 2, 2022 at 9:29, Teemu Saarinen</div><div>&lt;teemu.saarinen@netum.fi&gt; wrote:</div> </div> <div style="padding: 10px 0 0 20px; margin: 10px 0 0 0; border-left: 1px solid #6D00F6;"> <div id="yiv5482726687">
