Evidence
The midplane and the internal manifolds are shipped together as a module. The mechanical design of this module is shown in the picture above. These highlighted mechanical parts acts as a loading mechanism for the modules. These loading mechanisms ensure the modules are well connected to the Paladin connectors and the MQD by applying some force to the modules locking them in place.
Context After
Rack Level Infrastructure: Thermal
Beyond the redesigned fanless front chassis and the 100% liquid-cooled compute tray, the most notable point in the Vera Rubin cooling architecture discussion was Jensen’s comment on coolant/water warm temperatures and the use of chillers. For many (for Mr. Market more broadly!) the statement that Vera Rubin can operate with 45C inlet temperatures, potentially avoiding mechanical compressor-based chillers, was viewed as a major surprise for much of the cooling supplier ecosystem. We instead view this as a continuation of existing trends.
