Hi, what exactly do you mean with compatibility? You'll most likely be able to expand the cloud, but hardware differences could (and probably will?) impact live migrations between compute nodes without tweaking some stuff. For example, we had to find the correct "cpu_models" config value in nova.conf to be able to migrate between older and newer compute nodes. I'm not sure what else could go wrong, it really depends how the entire infrastructure is configured, your question is too vague. Regards, Eugen Zitat von nahoms@altacomputec.com:
The customer currently uses 15 Dell PowerEdge R650 servers for their OpenStack private cloud and wants to expand. Is there any compatibility issue if we propose Lenovo servers along with the existing Dell ones?
