唔知 Mega-i 有冇轉 genset

港島停電

同埋啲 exchange building 有冇跳曬 genset

Genset 即係乜

發電機？

係

咁真係唔知
不過咁快有返電佢現場啲人應該fallback返？

我屋企停咗成個鐘都有

datacenter 啲 UPS 淨喺夠撐 15 分鐘

一跳 UPS 就有 signal trigger genset 開機

之後就一路都係 genset，除非有人手動切換翻

電網停咗半秒

照計UPS實頂到

未必？有diesel應該要有人在場先開得？

咁大個DC一定有人架喎

啲 genset 係自動開嘅

咁癲？

UPS 有 signal 線去 genset

大部分 datacenter 都係噉

一有 signal 就會撻着發電機

無參觀過呢part

以為着alarm跟手真人着機lol

因為發電機要時間撻着

所以一定係 UPS sense 到無市電就即刻有 signal 去開 genset

the AMF signal is typically delayed for two to 10 seconds after mains power failure detection

如果佢地跟呢個post, 應該未必trigger到

genset無事嘅,係genset後面undervolt relay問題

你樓下咪洪洪洪緊,個時

interlock好depend佢有幾chok

乜係undervoltage relay

volt dip個時會出alarm同停供電黎避免後面device受損

但琴晚0040-0140都dip左幾多下

Sosad

何止 dip 😆

你用乜去量度

學下嘢

UPS 有 log 🤔

yes boom today

me waste 7 hours to recover k8s

a wtf boom

even cyberport got outage

commercial power

未有原因

所以除非係港燈值班 唔係唔知咩事

that wasted my valuable time and almost corrupted my etcd database

你個邊另計

點解會無 NAS

we suck

我嗰啲practice太rubbish
同埋買個新嘅for rack, 係咪都係得APC

APC 同 Eaton

Yes
Where were you

或者 Rhello

平野嘅話 cyberpower

無update開， @sstevefan1999 自己開startup啦？

k8s cannot sustain power outage seems to be a major drawback
