 * Hadoop 叢集
   * 升級至 Lenny
   * 重新蒐集 MAC Address 讓 hostname 盡量與 KVM 順序相仿
   * 安裝 Power Management ，由於機房有限制單一插座總電流不得大於 12 安培，因此不能插滿八個電源孔。
   * [消防/資安] Power KVM 的電源線也必須注意可容納的電流上限。

 || Power KVM || 1G || 2A || 2B || 2C || 2D || 2E || 2F ||

== Hadoop ==

 * 從 Y!TW 蔡奕楷 [http://www.openfoundry.org/index.php?option=com_docman&Itemid=112&gid=255&lang=en&task=cat_view 12/06 的 Hadoop - Open source grid computing platform 演講投影片]，看到一個有趣的指令叫 hod，回想起先前在 Hadoop 官方網站上看到的 [http://hadoop.apache.org/core/docs/r0.18.3/hod.html Hadoop On Demand]，簡單瞄了一下文件，HOD 主要是用 Python 寫的格網叢集佈署工具，用 Torque 或 Maui 當資源管理(Resource Manager)和排程器(Scheduler)。雖然文件裡寫著 Virtual Hadoop Cluster，不過沒有看到虛擬化技術的需求跟描述，因此應該僅僅只是在實體叢集中，切割部分節點來組成一個 Hadoop 叢集。

== Virtualization ==

== MapReduce ==

 * 持續蒐集一些 MapReduce 不同語言的實作....
