In a stable, enterprise-grade server room or data center, the TDP roughly equates to the computing equipment's power consumption, since the servers are usually operating at or close to maximum capacity. How to improve thermal management to accommodate a higher TDP has become an area of interest in the era of high performance computing (HPC), as IT experts try to get more computing power out of their processors.
Air-cooled servers: GIGABYTE's air-cooled servers come with a proprietary airflow-friendly hardware design, which means the direction of the airflow within the chassis has been evaluated with simulation software, and then fine-tuned to optimize ventilation. Powerful fans, high-performance heat sinks, and special air ducts or shrouds are installed to further improve the airflow. Other creative and unique modifications, which may differ between the various product lines, enable GIGABYTE to lead the industry in thermal management and allow for higher TDPs that unlock the full extent of the processors' computing power.
Liquid-cooled servers: Liquid cooling, also known as direct liquid cooling (DLC) or direct-to-chip (D2C) liquid cooling, uses sealed tubes (called cooling loops) filled with coolant to disperse heat. GIGABYTE has teamed up with a leading cooling solutions provider to provide high-density, factory-installed liquid-cooled servers. For instance, GIGABYTE has deployed a liquid-cooled HPC cluster in the data center of the German National Aerospace Center (DLR), so it can utilize superb processing power in the fields of aviation, aerospace, and transportation, without increasing the carbon footprint.
Single-phase immersion cooling: The apex of data center cooling is immersion cooling. The single-phase variant soaks the servers in a bath of dielectric, nonconductive coolant, and then cycle the warm coolant to a coolant distribution unit (CDU) to remove the heat. Not only does this reduce the data center's power consumption and carbon footprint, it is possible to have a higher ambient temperature and a higher TDP, which will unleash more computing power. GIGABYTE has provided a single-phase immersion cooling solution for Japan's telco giant KDDI.
Two-phase immersion cooling: The two-phase variant has the coolant undergoing a recurring cycle of vaporization and condensation inside a sealed tank. This process transfers the thermal energy from the server to the liquid coolant, and then to the rising vapors that are cooled by the condenser at the top of the tank. GIGABYTE has built a “two-phase immersion cooling solution” for the IC foundry giant that leads the world in advanced process technology; it has helped the industry leader achieve PUE below 1.08 and an increase of more than 10% in chip performance.
