SUMMARY:Computational Design of Dense Servers for Immersion Cooling
DESCRIPTION:Milin Kodnongbua and Zachary Englhardt (University of Washingt
 on); Ricardo Bianchini and Rodrigo Fonseca (Microsoft); Alvin Lebeck (Duke
  University); Daniel S. Berger (Microsoft, University of Washington); Vikr
 am Iyer (University of Washington); Fiodar Kazhamiaka (Microsoft); and Adr
 iana Schulz (University of Washington)\n\nThe growing demands for computat
 ional power in cloud computing have led to a significant increase in the d
 eployment of high-performance servers. The growing power consumption of se
 rvers and the heat they produce is on track to outpace the capacity of con
 ventional air cooling systems, necessitating more efficient cooling soluti
 ons such as liquid immersion cooling. The superior heat exchange capabilit
 ies of immersion cooling both eliminates the need for bulky heat sinks, fa
 ns, and air flow channels while also unlocking the potential go beyond con
 ventional 2D blade servers to three-dimensional designs. In this work, we 
 present a computational framework to explore designs of servers in three-d
 imensional space, specifically targeting the maximization of server densit
 y within immersion cooling tanks. Our tool is designed to handle a variety
  of physical and electrical server design constraints. We demonstrate our 
 optimized designs can reduce server volume by 25-52\% compared to traditio
 nal flat server designs. This increased density reduces land usage as well
  as the amount of liquid used for immersion, with significant reduction in
  the carbon emissions embodied in datacenter buildings. We further create 
 physical prototypes to simulate dense server designs and perform real-worl
 d experiments in an immersion cooling tank demonstrating they operate at s
 afe temperatures. This approach marks a critical step forward in sustainab
 le and efficient data center management.\n\nRegistration Category: Full Ac
