Hi Harald, OSD count means the number of disks you are going to allocate to ceph, you can change the whole column by clicking on the "OSD #" at the top of the table. And there's some predefined recommendation for various use cases named: "Ceph Use Case Selector:" you can find it on the same page. I'm not sure if it's really a best practice or not but you may have a look at "All-in-one" use case because you are going to use openstack and rados and lvm.
