Proxmox + Ceph on three identical public servers ?

[microlinux]

Hi,

I'm currently fiddling with Proxmox and Ceph on a handful of local sandbox machines, and I'm slowly wrapping my head around it.

Most of my current hostings (web servers, mail servers, various applications) are on bare metal servers, and I'm considering moving them to Proxmox. All of these are running on Dedibox root servers by Online/Scaleway in France. These are real servers (e. g. not virtual servers), and they're capable of acting as KVM hypervisors.

Is it feasible (in theory) to setup three Proxmox servers on three public machines (not necessarily in the same datacenter) and then build a high availability cluster with them using Ceph?

Cheers from the sunny South of France,

Niki

They should be close to each other, i.e. be connected with powerful (10Gbps for Ceph, 1Gbps for Cluster) LAN to each other. In other word have to be in the same datacenter. Even the protocol allow to connect the nodes via WAN such a setup will not work reliably.

OK. Thanks very much.
