Reduce Costs, Save Energy and Improve Performance
 
As the performance of CPUs and GPUs continues to increase, the heat that these processors generate continues to grow. While the work (operations per second) performed per watt also increases, the density of these new generations of servers that contain multiple CPUs and the latest generation of GPUs is also growing. Air cooling, which brings cooler air over the hot CPUs, relies on the temperature of the inlet air and the amount of air passed over the hot chips. To keep the CPUs within designed thermal envelopes, the inlet temperature and the capacity of the fans to move air (CFM) are critical elements of maintaining a server running at desired clock rates. Air cooling requires high energy usage computer room air conditioning and server fans running constantly. To reduce OPEX, liquid cooling is a viable alternative to CRAC and will become more prevalent in the future as CPUs will generate more heat with each new generation.

RACK SCALE ADVANCED ENGINEERING
As the Rack becomes the unit for scalable computing, engineering a liquid cooled rack requires careful planning and expert assembly. A liquid cooling system needs to be flexible to handle a wide range of servers, while being able to cool an entire rack of high performance systems

COMPONENTS OF AN EFFICIENT LIQUID COOLING SOLUTION
Supermicro’s liquid cooled rack solution is made of several components that are designedin house to achieve the highest level of performance and reliability. All the components are integrated as a rack level solution providing a true one-stop shop customer experience.
 
 
 
Coolant Distribution Unit (CDU)-

contains the pumping system that circulates the coolant to the cold plates cooling down the CPUs and GPUs. The Supermicro CDU integrates 2 hotswappable and redundant pumping modules and power supply modules guaranteeing nearly a 100% uptime to the operator. The CDU cooling capacity is up to 100kW enabling extremely high rack densities. The CDU also offers an easy-to-use touch screen to monitor and control the rack operation with WebUI access and integrated in Supermicro’s Super Cloud Composer datacenter management software. The CDU control system optimizes power consumption while ensuring efficient cooling is delivered to all the CPUs and GPUs. An effective anti-condensation strategy is adopted to prevent any hardware degradation.
 
 
 
 
 
 
 
 
 
Coolant Distribution Manifold (CDM)
 
The CDM are the distribution pipes that supply coolant to each server and collect the hotter coolant back to the CDU. There are two types of CDMs:
Vertical
Vertical manifolds are placed at the back of the rack and directly connected to the CDU with hoses. They deliver coolant to the cold plates on systems with inlet and outlet hoses at the back of the rack.
 
Horizontal
Horizontal manifolds are placed at the front of the rack in a 1U rack mount space. They connect the vertical manifolds at the rear of the rack to cold plates on systems with inlet and outlet hoses at the front of the rack (SuperBlades and 8U GPU servers)
 
Hoses and Connectors
Flexible hoses are used to bring the cooler liquid to the CPUs and GPUs cold plates and return the hot liquid to the CDMs. The Supermicro connectors are single handed, 0 drip, quick disconnector, they allow operators to service liquid cooled systems
safely and efficiently.
 
Cold Plates

The cold plates are placed on top of the CPUs and GPUs; flowing coolants through their micro sized channels cools down the chips very efficiently. The Supermicro cold plates are designed to reduce hot spots on the chip and reach ultra-low thermal resistance.
