So I'm deploying openstack xena using kolla ansible, and i've used infiniband network to connect between the serves of my cluster, however I was wondering whether it is advisable to use a single interface for for " *api_interface*" and "*storage_interface*" and " *tunnel_interface*" or maybe using separate interfaces would be better? Furthermore, I want to ask if using *ipoib *for the infiniband network is a better option than a regular ethernet rg45 network. Thank you all. -------------- next part -------------- An HTML attachment was scrubbed... URL: <http://lists.openstack.org/pipermail/openstack-discuss/attachments/20220629/416cfe0e/attachment.htm>
