[ceph-users] Something like RAID0 with Ceph

Hello, Is it possible to have something like RAID0 with Ceph? That is, when the cluster configuration file contains osd pool default size = 4 and I have four hosts with one osd drive (all the same size, let's call it size s) per host, is it somehow possible to add four other hosts with one osd drive (again with size s) per host, so that the resulting Ceph block device is of size 2 * s?
