[ovirt-users] basic infra and glusterfs sizing question

Hello, I am just curious if basic gluster HCI layout which is suggested in cockpit has some deeper meaning. There are suggested 3 volumes * engine - it is clear, it is the volume where engine vm is running. When this vm is 51GB big how small could this volume be? I have 1TB SSD storage and I would like utilize it as much as possible. Could I create this volume as small as this vm is? Is it safe for example for future upgrades? * vmstore - it make sense it is a space for all other vms running in oVirt. Right? * data - which purpose has this volume? other data like for example ISOs? Direct disks? Another infra question... or maybe request for comment I have small amount of public ipv4 addresses in my housing (but I have own switches there so I can create vlans and separate internal traffic). I can access only these public ipv4 addresses directly. I would like to conserve these addressess as much as possible so what is the best approach in your opinion? * Install all hosts and HE with management network on private addressess * have small router (hw appliance with for example LEDE) which will utilize one ipv4 address and will do NAT and vpn for accessing my internals vlans. + looks like simple approach to me - single point of failure in this router (not really - just in case oVirt is badly broken and I need to access internal vlans to recover it) * have this router as virtual appliance inside oVirt (something like pfSense for example) + no need hw router + not sure but I could probably configure vrrp redundancy - still single point of failure like in first case * any other approach? Could ovn help here somehow? * Install all hosts and HE with public addresses :-) + access to all hosts directly - 3 node HCI cluster uses 4 public ip addressess Thanks for your opinions Cheers, Jiri
