Hallo,
you have to read the fine print:
OS / platform support covers SAP HANA client component / application server only
The stated operating system / platform support covers the SAP HANA client component only, usually installed next with the SAP application server. You must use SLES 11 or RHEL 6 (starting with Revision 80 of HANA database) on x86_64 to install and use SAP HANA database / server components.
Regards
Thomas.
