Is there any official SAP white paper or SAP note that states that HANA does not use swap memory?

Lars, thank you for the interesting blog:-

I have a customer asking the same question around Swap memory. So both, the Customer and I know that HANA is not designed at all to run off swap memory. Do you know of anything officially mentioned by us like a SAP note or white paper that specifically states this?

Check SAP KBA 1999997 - FAQ: SAP HANA Memory, hopes it helps.

21. How much swap space should be configured for SAP HANA hosts?

It is recommended to configure a small swap space in order to avoid performance regressions at times of high memory utilization on operating system side. Instead it is usually better if activities are terminated with "out of memory" errors. This makes sure that the overall system is still usable and only certain requests are terminated. A good value for the swap space is 2 GB (see e.g. SAP Note 1944799 for SLES environments).
