Notes:

* The support statements refers to hardware control, operating system (os) provisioning, and general purpose system management where we do not see any obvious problems with the indicated combination.

* For xCAT < 2.17 diskless mixed cluster support, the initial diskless image must be created on a node running the target operating system version and architecture. On xCAT >= 2.17 with x86 based management nodes QEMU emulation can be used for different architectures (eg. ppc64 or aarch64) if qemu-user-static is installed and configured via systemd-binfmt. See :doc:`/advanced/mixed_cluster/building_stateless_images` for more details.

.. rubric:: Footnotes

.. [1] To manage x86_64 servers from ppc64/ppc64le nodes, will need to install the packages **xnba-undi elilo-xcat** and **syslinux-xcat** manually on the management node. And manually run command "cp /opt/xcat/share/xcat/netboot/syslinux/pxelinux.0 /tftpboot/"
.. [2] If the compute nodes are DFM managed systems, will need xCAT 2.9.1 or high versions and the ppc64le DFM and ppc64le hardware server on the management node.
.. [3] If the compute nodes are DFM managed systems, will need xCAT 2.10 or high versions and the ppc64le DFM and ppc64le hardware server on the management node.
.. [4] If the compute nodes are DFM managed systems, will need the ppc64le DFM and ppc64le hardware server on the management node.
.. [5] Does not support DFM managed compute nodes, hardware control does not work.
