SUMMARY:Middlebox: Resolving the Datacenter-Grid tension and Decarbonizing
  Both!
DESCRIPTION:Andrew Chien (Univ of Chicago, Argonne National Laboratory)\n\
 nDatacenter’s (DCs) constant power requirement is difficult to balance wit
 h variable solar and wind generation.  DC load flexibility is the key to s
 olving the problem, but it conflicts stable capacity requirements.\n\nWe p
 ropose ``power Middlebox'', a new system architecture, as a bridge. Middle
 box decouples datacenter capacity and grid load, reconciling the conflict 
 between DC capacity needs and grid load flexibility requirements and provi
 ding each with freedom to meet their divergent objectives. We define Middl
 ebox system architecture, frame its objectives, and explore designs (type/
 quantity of energy resources, extent of decoupling, management) in varied 
 power grid settings.  \nEvaluation shows that Middlebox unlocks 460% or 17
 0% datacenter growth with grid reliability or decarbonization constraints 
 in a wind-dominated grid. We study decoupling in growing DC scenarios. Dec
 oupling reconciles the conflict between grid and datacenter needs, enablin
 g constant DC power capacity on 99.9\% of days, for a cost equal to 37% of
  a DC's annual power bill (or 3--5% of DC TCO). Future technologies could 
 reduce Middlebox cost by up to 70%. Further, workload flexibility can be e
 xploited to reduce cost. These results are robust across growth scenarios,
  grid types, and datacenter size.  Our  results show that Middlebox can be
  deployed economically with today's technology.\n\nDomain: Engineering, Co
