Hi :) We discussed a lot about that. First and direct answer: you won't find "the best". It all boils down to: **1. What you are intend to do** **2. What is your current hardware** **3. What kind of load you at least expect.** Here is a first thread: http://www.gossamer-threads.com/lists/openstack/dev/24231 and another interesting one: http://www.gossamer-threads.com/lists/openstack/dev/24231 in a nutshell, I myself tested many clustered or shared FS, and they all have their pros and cons. In my top list, I ended up having: - MooseFS - Ceph (but not CephFS) - ISCSI only because they happened to work well with my environments, they "did the job" Let us know if you have any specific questions regarding these technologies Razique On 28 Nov 2013, at 0:44, Alvise Dorigo wrote: > Hello, > I'm setting up an openstack-based cloud IaaS.
