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- QEMU
You 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
