Re: Case of CEPH Environment Hyper-converged


At PCextreme we use CEPH + KVM. Ceph can perform well, but it depends on hardware, architecture, and configurations (as any technology). KVM is the same deal, it performs well and it is stable.

Just to be clear, there are many production environments running with KVM and Ceph out there; if hyper-converged fits well with your needs it sure can be applied with CloudStack + KVM + Ceph.
