Hi, Thats sound like a fake, sorry. A single-core CPU with a some piece of RAM as file server for 200 users? No... Buy a new hardware with 4 or 6 cores, 16GB RAM and a raid controller and some disks. Then copy your data from the old system on the new raid system and everything is fine.
You didn't answer the OP's question. And your upgrade recommendation is complete overkill. A modern ~2Ghz Sempron can easily saturate a GbE pipe without using jumbo frames. 1GB of RAM is plenty for serving 200 office environment Samba clients--512MB would even be sufficient. If he's lacking performance it's due to insufficient head seeks bandwidth. He didn't mention a capacity shortage and he currently has ~250GB of disk. A single 250GB SSD would solve that problem instantly for $400-600 USD with an MLC drive. Two mirrored would be better, so $400-1200 USD. This would yield 50,000 seeks/second vs the 300 he has now, and ~250MB/s bandwidth, vs the ~160MB/s he currently has.

My user using server for data sharing, myob, etc. My trouble is my server like "sleep" and if it's sleep i cannot ping, ssh and anything from another computer, to "wakeup" my server i must hit any button in the keyboard(server keyboard) and i can ping again and after 10-15 minutes it is sleep again. I'm using two harddisk, 80GB(system and home partition but system and home partition located at different partition), 160GB(user data sharing like office file, accounting file). At second harddisk(160GB) have partition error but i can't using fsck because if i'm running fsck force it is can delete the important data because my backup server not running(down) and i must backup manually. My log file like syslog and kern.log did not show any error, it is running like my system is normal, i'm check with lsof +D /var/log my ryslogd runs well. My question is what causes my debian squeeze act like it?, i'm using debian from sarge, etch, lenny and i have never encountered this problem and i'm believe debian still best linux distribution i'm ever have..:-) Any idea list?, thanks before for helping
Yes. Turn off all power saving features in the system BIOS. A headless installation has no power saving by default AFAIK, so apparently you're running a GUI desktop. Find the power management application in one of the control panels and disable all power saving features. They only cause headaches on servers, as you've discovered. Unless you truly *need* a GUI on your server console, get rid of it. If you need a GUI to manage a Linux server then I'd say you really need to sharpen your admin skill set.
Best of luck. -- Stan
