Understanding Liquid Cooling in Servers

The video tutorial by Patrick from STH explores a unique liquid-cooled server setup at CoolIT Systems in Calgary, Canada. It features the Gigabyte H262-ZL0 server, which uses AMD EPYC Milan CPUs cooled by a liquid cooling distribution unit (CDU). The tutorial provides a comprehensive guide on assembling the cooling system, explaining the components and their functions. It highlights the efficiency of liquid cooling in data centers, demonstrating how it can cool thousands of server cores using minimal water flow. The video emphasizes the importance of liquid cooling for future high-performance computing needs.

What is the primary focus of the video featuring the Gigabyte H262 ZL0 server?

• Air cooling techniques

• Liquid cooling in servers

• Server software installation

• Networking configurations

What is the main difference between the ZL0 and ZL1 models of the Gigabyte H262?
