SUMMARY:Taming Datacenter Thermodynamics with Lenovo Neptune Technology
DESCRIPTION:Matthew Ziegler and Vinod Kamath (Lenovo)\n\nLenovo has been d
 elivering solutions based on liquid-cooling since 2012 and installed the f
 irst x86-based warm-water (50°C intake) cooled cluster at Leibniz-Rechenze
 ntrum (LRZ) in Munich, Germany.  The latest generation of technology based
  on direct to node (DTN) liquid cooling, the Lenovo ThinkSystem SD650 that
  directly cool the CPUs (up to 240W), IO, RAM, HDDs and voltage regulators
 .  Another liquid-cooling based approach Lenovo uses is a novel heat-sink 
 which uses water to move heat away from a processor via a hermetically sea
 led heat pipe located inside a wide rear heat spreader.  This Thermal Tran
 sfer Module (TTM) allows for servers to run processors up to 205W in tradi
 tional dense form-factor. Finally,  Rear Door Heat Exchangers (RHDX) extra
 ct server heat from the exhaust air before entering the datacenter through
  liquid passing through the rear rack door.  These three technologies make
  up the Lenovo Neptune family of liquid-cooled solutions.\n\nTag: HPC Cent
