IDC　(Internet　Data　Center)　Engine　room　plays　a　core　role　in　large　IT　enterprise＇s　operation　and　management　of　data　exchange　and　processing.　Taking　advantage　of　scientific　and　intelligent　ways　to　realize　management　and　control,　is　prerequisite　to　IDC　engine　room＇s　efficient　and　stable　work.　Aimed　to　solve　the　traditional　IDC＇s　serious　problems　such　as　information　collection　lag,　not　timely　alarming　and　poor　performance　on　saving　energy,　we　designed　and　implemented　a　set　of　intelligent　management　and　control　systems　in　IDC　engine　room　based　on　data　mining　and　early　warning.　This　Paper　firstly　describes　the　system　structure　and　function,　then　focuses　on　key　technologies　such　as　nonlinear　regression　early　warning,　improved　Apriori　data　mining,　SMS　(Short　Messaging　Service),　and　ultimately　shows　experiment　results　and　real　implements　of　the　system　based　on　early　warning　alarm,　data　mining,　real-time　analysis.　This　intelligent　system　has　been　successfully　deployed　in　IDC　of　China　Unicom　and　has　been　proved　accurate,　stable　and　efficient.　©　2012　IEEE.
