Hi Lori,
if i understand you question well::
HANA DB only run on SLES 11 SP1 and above. However, in HANA landscape, even with standard installation, you need to have a standalone CI and standalone DB. Your standalone CI can run on any platform certified in PAM, eg: AIX, HP and etc, But your HANA DB must run only on SLES 11 SP1 and above.
Hope it clears your doubt.
Thanks,
Nicholas Chang
