「從麻雀之城回來的時候,被問到『你要大的藤箱還是小的藤箱?』為此煩惱不已。大家都有過這種煩惱吧?」
「是啊是啊!大的藤箱可以放很多東西覺得很划算,小的藤箱小小的裡面也許放著很不錯的東西,真的很難取捨阿!」
「靠這個就能告別這種煩惱『中型的藤箱』!」
「好厲害!」
「不要再煩惱大小的問題了,現在還贈送可以煮出鐵質,增進健康的鐵銼刀。」
「這是一定要買的!」
「我要一個!」

這幾款ZCR Linux kernel都有支援, 使用
<*> Adaptec I2O RAID support即可!

我這裡有一台跑了快一年還算穩定。
建議如果可能的話跟廠商借測一下,可以用再買。
ASR-2010S [Zero-ChANNEL SCSI RAID 控制卡,U-320]
這張廠商報價才$10,500, 應該值得一試。

不過ZCR似乎要搭配onboard scsi chip使用,如果沒有onboard scsi chip可能至少要買single channel的, 這部分可以問問廠商。總之用hardware raid會省事很多。

謝謝你pahud,我大概會買Palatis兄推薦的主機板
.就你所說的買ZCR的raid card需要主機板有onboard.我也查過支援的主機板不多,至少我想買的這一個主機板沒有.所以我會考慮這一塊raid card(ADAPTEC ASR-2120S)你可以由以下的連結看一下他的報價和他的規格

不知道你是否有用過這一個raid card,謝謝!

小弟用hardware/software raid 我用過一段時間了,有幾點提供你參考:

1. 除非你真的有在software raid上處理過 restore的經驗,且對software raid tool (raidtools or mdadm)很瞭解不然建議你不要用software raid。到時資料crash ...卻不會救的話,眼淚會流不下來。何況你這機器那麼重要的話,更要對software raid很有管理的經驗才行。

2. software raid如有crash 狀況發生,你要umount 救資料的話,在linux2.4的kernel 是不可能的,到時你只能reboot...如果這是7*24的機器的話.....恩......為什麼要umount?這要問linux kernel 與 raidtools的配合嘍,小弟有發生過df 出來的大小不是實際的大小,偏偏那時寫進去的資料都不知道寫到哪去了?!一定要umount在mount才行!這些部分討論可以在google上找到。

3. software raid 在做data rebuild時比hardware raid慢上許多,尤其你又是做raid 1....更慘....如用4顆做raid5....慘上加慘
如果你預計用你之前說要用raid 0+1的話.....拍謝,software raid不能做 :lol: 要做的話,請用evms2 幫你create virtual device node 吧!我有成功過 :D

4. 你用hardware raid...如果你為了省錢,cpu時脈用比較低的話,你在做rebuild時也會等到天荒地老,rebuild過程,又死一顆的機率比一般資料存取還高。

除非:
a. 你買的raid card 上面有cpu那種的。
b. 你用FC disk 可能也會快一點。傳輸快,但是還是受限你cpu運算。


小弟建議你,重要server最好用 hardware raid....
software raid 在desktop or non-critical server 玩玩就好
