Greetings, We're about to use OVN in a large production environment :-)
Well, not really "production" production, but having fun testing it, looking if we can use it in such way. While functionality is good for us, two question appear - scalability and availability. What are current OVN (as of master branch) limitations in hypervisors in one segment (one SBDB), lswitches in one segment, lports in one lswitch, etc? About clustering. Since ovn-northd does not support clustering by itself, it is possible to create active-passive HA cluster ising third-party clustering software. NBDB and SBDB are replicated using ovsdb mechanisms and clustering software ensures that there are one copy of ovn-northd daemon is running. Is this correct? Can ovn-controller's automatically switch to different database server? What clustering/HA/scalability features are planned for 2.6.0 release? Thank you in advance. -- Regards, -- Sir Raorn. --- https://plus.google.com/+AlexeyFroloff
