如果要起一個 extranet, 服侍 30 個國家, 大約 2000 個 user, 要分開 web-server 同 database server, 個問題係:

1) 兩台 server 要乜 config?

2) 條 leased-line 要幾大 bandwidth?

3) 另外要乜其他 hardware 同 software?

Thank you!

>>服侍 30 個國家

請問大概是那些地區?
歐美的話要找PCCW了.


1) 兩台 server 要乜 config?

Database server: as much ram and CPU power as possible.
Xeon/A64 if got $$$
Please use MySql as far as possible.

web server: P4 HT with a couple GB of ram will do. But how many services are you running on the web server? Just static pages or lots of PHP scripts?

2) 條 leased-line 要幾大 bandwidth?

I have to see your answer on the first question before giving advice on this.

3) 另外要乜其他 hardware 同 software?

Again ust static pages or lots of PHP scripts? For web server I think linux (with apache, PHP configred) will be enough.

Having 2 servers might be overdoing IMO through. However I can't really comment because I don't know the actual application yet.

1) Web : Dell 2850, 2 x Xeon, 2G ram.
database ： 都係 dell 不過要睇你既database 使唔使行 san 喎。

2) 呢個好 depands 你個database 行起黎有幾大食喎, 仲有你個 web application 既 behaviour 係點行既呢？

3) web 行 tomcat 喇。database 行 raid，大ram 無得走，而家買親都會係 giga ethernet 架喇。不過個 bottom line 會係個 leased line。你係咪 con-current 有 2000 個 connection ？

哈哈 ~ 我鍾意啊 ~ V902SH, you will be unlocked!

1, 要知你行乜野os(windows?linux?bsd?solaris?) 乜野db(mssql,db2,oracle,mysql,pgsql?), 乜野app?

2, con-current 幾多人, 你的app. need幾多bw per con, extranet 意思是否經internet?

3, 答左上面的問題, 呢到先決定到.

ps, 我有2u rackmount srv賣架, if 用u160 scsi, 有特別disconnect.

Oh ........ I forgot ............. most of these countries are in Asia Pacific like Singapore, Thailand, Taiwan and etc ........

Also, we are Microsoft Partner so we have to Windows Server and also MS SQL database.

1) Database 一定要用 MS SQL ...... 因為我公司只可用 MS SQL!

2) Web Application 主要係 ASP

3) 唔會 concurrent 有 2000 個, 但月頭月尾會最忙, 因為要埋數!

1) Windows 2003 server + MS SQL server

2) concurrent 唔會 2000, 可能 200 左右. Extranet 是要經 Internet.

Thank you

啦, 你快d 比多少少info 我.
我叫個 network eng, 整張 network diagram比你.

2GB Ram 應該唔夠~

普通一個 data server 24 x 7 hours 就少 4 GB ram + Dual Xeon CPU 都慢
(PS : 之前我一個公司 Client company 的config...)

睇你個乜野program啦咁要.

我有個客行 sap 4個 modules 部機都係得2gb ram only.

my old client only run windows 2000 server ( is data server )

and her Exchange server is same config.....but always hang~

bez he need to link in Japan & Eup

Exchange 緊係啦.
多多ram都唔夠用.

佢個db 根本係垃圾.
叫佢買埋 mssql 裝入去行就會快好撚多架啦.

整緊 ....................

.....粗口.......

習慣左. 唔好介意.
因為我唔係咁like exchange, 雖然接佢d 單可以搵好多,
哈,
又愛又恨啊....

同埋 sap 真係好勁架套野, 佢可以confirm話每個 con 用50k bw.
