How Server Liquid Cooling Works: Cooling 20K Cores with a Garden Hose

We put together and review a Gigabyte H262-ZL0, 2U 4-node AMD EPYC server with 512 AMD EPYC cores. We then show you how liquid cooling works by hooking it up to a CoolIT Systems CDU. This little benchtop setup is enough to cool over 20,000 AMD EPYC "Milan" cores with a garden hose worth of water.

Check out the chapters to learn about whichever part you want. This is one long video.
