Just go to www.suse.com select the product SLES for SAP Applications, use the download button and in parallel generate a (free) evaluation key.
As a benefit you get the "correct" distrubution to run SAP and your learning can include the distrubution and how SUSE with SAP have worked on getting SAP running on Linux. This includes the automated start of uuid, sapconf which tunes the kernel parameters and even more.
