機房里有5台實驗用的Dell R710服務器，為了低碳環保，我決定只在工作日白天開啟它們，其余時間全部關閉。我選擇在linux下用ipmitool結合計划任務來實現，這里只記錄ipmitool工具的用法。IPMI（Intelligent Platform Management Interface）
ipmitool -I lanplus -H 10.197.82.105 -U root -P calvin power status|on|off|cycle|reset|diag|soft
1. iDrac 6對應的是lanplus，soft軟關機，off硬關機，reset軟重啟，cycle硬重啟
2. 詳見 http://ju.outofmemory.cn/entry/106893
