"Energy Proportional Datacenter Networks", 2010/08/01
  http://perspectives.mvdirona.com/2010/08/01/EnergyProportionalDatacenterNetworks.aspx

ネットワークチップ (Gemini) についてではなく、ネットワーク機器の消費
電力についてのコメントのようです (すいません真面目に読んでません)

ご自身が Microsoft時代に研究したネットワークトポロジーにも言及してい
ます (詳細はみて下さい)。



最後に
  "Summarizing the findings: My take from this data is it's a rare
   datacenter where more than 10% of power is going to networking
   devices and most datacenters will be under 5%. Power proportionality
   in the network is of some value but improving server utilization
   is a far more powerful lever. In fact a good argument can be made
   to spend more on networking gear and networking power if you can
   use that investment to drive up server utilization by reducing
   constraints on workload placement."
