Hi All, We are currently trying to deploy OpenStack on thousands of nodes. We are using Grizzly stable version and Ubuntu 12.04.2. However, the big problem we meet now is the network topology. If we want to use HA (haproxy + keepalived) for the controller nodes on which *-apis are running as well as network nodes which are deployed across different VLANs (VLANs can reach each other by setting gateways), e.g 10.1.0.0/16 and 10.2.0.0/16, HA would not work correctly. Also we found that rabbitmq could not work when nova-* services were deployed across different subnets.
Thus, we want to know whether HA and rabbitmq can be used across subnets? If it not true, we can only deploy them in a single flat layer 2 net, which seems unfeasible in real-world because of broadcast storms... Best, Kylin CG _______________________________________________ Mailing list: https://launchpad.net/~openstack Post to : openstack@lists.launchpad.net Unsubscribe : https://launchpad.net/~openstack More help : https://help.launchpad.net/ListHelp
