This is similar to Windows licensing (https://en.wikipedia.org/wiki/Windows_10_editions#Comparison_chart https://en.wikipedia.org/wiki/Windows_10_editions#Comparison...), where "Windows 10 Home" allows you to use 128 GB of RAM, while the various "Pro" versions allows up to 2 TB, and "Enterprise" up to 6 TB.
The limits used to be lower - I seem to remember laughing out loud at a Stack Overflow podcast, where they talked about having to purchase a new Windows license to be able to expand the RAM of a server.
- cheerlessbog 7y agoIt likely took some work in the OS to support the larger RAM... grow some data structures, tune caches and heap managers, test on new hardware. Yes it's price segmentation but it's not totally arbitrary.
- asjo 7y agoWell, you bought a new license and they the RAM was used. No installation of anything but the license. At least that's how I remember the podcast explaining it.
