Kilo is a bit old but the good news is that CPU pinning is available which IMHO is a must to run C* on Production.Of course your bottleneck will be shared HDDs.Best,RomainHi Romain,Thanks for the input!We currently use the Kilo release of Openstack. Are you aware of any known bugs/issues with this release?We definitely defined anti-affinity rules regarding spreading C* on different hosts. (I surely don't want to be woken up at night due to a failed host ;-) )Regarding Trove, I doubt we'll use it in Production any time soon.Thanks again!On Mon, Dec 26, 2016 at 7:37 PM, Romain Hardouin <romainh_ml@xxxxxxxx> wrote:Hi Shalom,I assume you'll use KVM virtualization so pay attention to your stack at every level:- Nova e.g. CPU pinning, NUMA awareness if relevant, etc. Have a look to extra specs.- libvirt- KVM- QEMUYou can also be interested by resources quota on other OpenStack VMs that will be colocated with C* VMs.Don't forget to define anti-affinity rules in order to spread out your C* VMs on different hosts.Finally, watch out versions of libvirt/KVM/QEMU. Some optimizations/bugs are good to know.Out of curiosity, which OpenStack release are you using?You can be interested by Trove but C* support is for testing only.Best,Romain
