This will come down to the Raid Controller installed in the servers. With the H710 (T620) and H730 (T630), then YES Raid 6 and 60 are supported, as is with the H330 (T630).   Yet none of the S controllers (S110 (T620)or the S130 (T630)) will support Raid 6 or 60, neither will the H310. Could you confirm the raid controller installed, if any?
