在APC 的廣告email發現了這個訊息，貼在這邊當作自己的memo.

Q:What is the expected life of an APC UPS battery?

A: All APC batteries should last three to five years. Below are some guidelines to ensure optimum life expectancy:

-> 這還真的只撐了三年

1. Make sure that the APC UPS battery is kept in a cool, dry location with plenty of ventilation. Ideally, the temperature where a UPS is kept should not exceed 75° F (24° C). Also, for ventilation purposes, leave roughly one to two inches on each side for proper airflow.

->這點大概沒有達到吧，台灣的夏天，室內應該也有30°C吧～晚上是會開冷氣，因為我也受不了那麼熱。 Read more »

APS Smart UPS 掛點

Posted in Daily, Linux, Storage on February 18th, 2008 by Banbanli

sua1000.jpg在server 掛點之後，某天凌晨三四點，UPS 警鈴大作，我迷迷糊糊的起來，看到replace battery 的燈亮了，這樣也合理，呼應了之前server掛點的徵兆。

上星期把UPS拿去給廠商，準備更換電池，今天接到電話了，由於APS有自己獨特的電池組，所以要價$5500NTD大洋，好貴阿～不過還是要縮下去。

這次，真的要來好好的備份資料了，準備了3ware SATAII PCI-E 2port 作Raid 1 mirror, HD選的是Seagate Barracuda® ES ，另外獨立用主機板的SATA cable 掛了一個HD 每天跟Raid 1 作rsync。

每個月再把資料用DVD-R 備份起來。

B52的資料，也同時用rsync over SSH 異地備份到Leon的主機。

大概就這樣子了。資料不見真的很痛。

相簿系統

Posted in Linux on June 1st, 2007 by Banbanli

今天check相簿系統，在跟目錄第三頁好像有點問題，可能是在更新CentOS的時候，因為Yum dependence 的issue, 手動remove php package 的時候，造成的。

等等再去改改php.ini好了
