What is the expected life of an APC UPS battery?

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。

真是太震撼了
以後的SATA II Drive Seagate將會穩作第一，
WD會不會被拋在遠遠的後面？

Seagate shells $1.9B for Maxtor
Seagate Technology LLC. and Maxtor Corp. announced they have entered into a definitive agreement under which Seagate will acquire Maxtor in an all-stock transaction. Under the terms of the agreement, which has been unanimously approved by the board of directors of both companies, Maxtor shareholders will receive .37 shares of Seagate common stock for each Maxtor share they own. When the transaction is completed Seagate shareholders will own approximately 84% and Maxtor shareholders will own approximately 16% of the combined company. The value of the transaction is approximately $1.9 billion.

SATA 2.5將一統SATA II規格？

Posted in Computer, Storage on October 25th, 2005 by Banbanli

最好是這樣子
不然光作相容性測試, 就勞民傷財了

我還以為只有網路的application有相容性, 想不到連儲存產品也會 🙁

SATA 2.5將一統SATA II規格？
文/黃彥棻 (記者) 2005-10-24

硬碟廠商紛紛推出SATA II規格的硬碟，強調每秒傳輸速度3Gb，以及具有原生命令佇列（NCQ）功能。不過，Serial ATA協會將於月底公布正式的SATA第二代規格SATA 2.5，並將進行認證。而希捷（Seagate）日前發表500GB的3.5吋SATA硬碟Barracuda 7200.9，就是目前第一款符合SATA 2.5規範的第二代SATA硬碟。

“Just A Bunch Of Disks” (JBOD)

Posted in Computer, Storage on October 5th, 2005 by Banbanli

最近常聽到,先 bookmark起來好哩

http://www.pcguide.com/ref/hdd/perf/raid/levels/jbod.htm

If you have some disks in a system that you decide not to configure into a RAID array, what do you do with them? Traditionally, they are left to act as independent drive volumes within the system, and that’s how many people in fact use two, three or more drives in a PC. In some applications, however, it is desirable to be able to use all these disks as if they were one single volume. The proper term for this is spanning; the pseudo-cutesy term for it, clearly chosen to contrast against “redundant array of inexpensive disks”, is Just A Bunch Of Disks or JBOD. How frightfully clever.
