SUMMARY:Taming Datacenter Thermodynamics with Lenovo Neptune Technology
DESCRIPTION:Exhibitor Forum\nHPC Center Planning and Operations\n\nTaming 
 Datacenter Thermodynamics with Lenovo Neptune Technology\n\nZiegler, Kamat
 h\n\nLenovo has been delivering solutions based on liquid-cooling since 20
 12 and installed the first x86-based warm-water (50°C intake) cooled clust
 er at Leibniz-Rechenzentrum (LRZ) in Munich, Germany.  The latest generati
 on 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 sealed heat pipe located inside a wide rear heat spread
 er.  This Thermal Transfer Module (TTM) allows for servers to run processo
 rs up to 205W in traditional dense form-factor. Finally,  Rear Door Heat E
 xchangers (RHDX) extract server heat from the exhaust air before entering 
 the datacenter through liquid passing through the rear rack door.  These t
 hree technologies make up the Lenovo Neptune family of liquid-cooled solut
 ions.
