 デル、最高45℃での使用も保証で外気冷却を支援"
 2011/08/24、@IT
  http://www.atmarkit.co.jp/news/201108/24/dell.html

  " デルは8月24日、事業者や企業のデータセンターにおける外気冷却への
   取り組みを支援するため、同社の法人向けIT機器の保証でカバーする
   温度範囲を拡大したと日本で発表した。1機種に限定したものでなく、
   同社の複数の既存サーバ、ストレージ、スイッチなどに適用される。

    具体的には、年間の合計稼働時間のうち、10%までを室温5~40℃、
   湿度5~85%、1%までを室温-5~45℃、湿度5~90%、そして残りの時間を
   10~35℃、湿度10~80%の範囲で動かす場合、これがデルの製品保証範囲に
   含まれるというもの。常時45℃の稼働を保証するというものではない。
   目的が外気冷却の活用支援だからだ。"

まだ Draftレベルですが、IBM Redpaperです:

"Smarter Data Centers: Achieving Greater Efficiency"
 Last Update: 2011/07/29, Planned Publish Date: 2011/08/31

  "This IBM Redpaper publication can help your IT organization as
   it begins the journey to becoming a smarter data center. IBM wants
   to help others, particularly our clients, to chart a course to reap
   the benefits of lower costs and improved sustainability that running
   a green data center can provide. Understanding what is possible can
   speed your journey to an optimized smarter data center with
   sustainability designed into both the IT and facilities
   infrastructures. Although this paper is not all inclusive, it provides
   a quick start for going green in data centers. It also provides
   additional pointers and information. You can use this paper as
   a guide to becoming more energy efficient."
