Dear operators, yesterday we (Performance Team) had weekly IRC meeting <http://eavesdrop.openstack.org/meetings/performance_team/2015/performance_team.2015-11-17-15.00.html>, one of the things on board to discuss was nova-conductor performance issue <https://etherpad.openstack.org/p/remote-conductor-performance> raised by Kris Lindgren (GoDaddy). There are still things to investigate and several suggestions about nature of this behaviour, but one of the questions/ideas raised was "If the conductor nodes to compute nodes ratio was ok?". In fact I never saw any recommendations on safe enough ratio for conductor nodes or networking nodes or whatever nodes vs compute ones. As providing OpenStack community with understandable recommendations and instructions on performant OpenStack cloud deployments is part of Performance Team mission, I'm kindly asking you to share your experience on safe cloud deployment ratio between various types of nodes you're having right now and the possible issues you observed (as an example: discussed GoDaddy's cloud is having 3 conductor boxes vs 250 computes in the cell, and there was an opinion that it's simply not enough and that's it). Thanks in advance! Cheers, Dina -------------- next part -------------- An HTML attachment was scrubbed...
