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 -
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.
