As suggested in the last post, the hard disk of the new server (currently named brisbane, the codename of the processor used) is a 133x 8GB ComplactFlash memory. However, I had been facing the problem of slow Windows installation (the installation takes more than five hours to complete).
After a sudden flash through my mind, I changed to Ubuntu Server 8.04 LTS. The installation takes no difficult steps provided one has enough computer knowledge. The major issue lies along the stripping disk configuration (because of c.en, I went to HK Golden Center with him and upgraded to two pieces of the 8GB CF card). The installation interface is capable of creating software disk arrays (RAID-0, RAID-1 and RAID-5 are supported). In the most common RAID-1 scenerio, a workaround is required to allow booting of another disk when one of the disks failed, which steps are detailed in many web-sites. However, it is not possible for RAID-0. I was quite suprising that many people in the net think that simular steps can be applied to RAID-0, the point is that in RAID-1, the two disks are identical, so booting either disk should work. But the boot loader must recognize a stripping set to boot a RAID-0 volume, which is not feasible. Currently, I put the /boot into a standalone logical partition (obviously, the software RAID feature supports arrays of logical partition!). You may find this paragraph very complicated, this is not a Linux's fault, it's just Windows not to support this (and many) kind(s) of highly customized and mature configurations.
After the server installation, it took around two hours to install GNOME (by installing ubuntu-desktop package). Since I have installed 6 GB of memory, I tried to get a RAM disk works in a minute (it's just a line in /etc/fstab with file system of tmpfs). Everything is as easy as asking Mr. Google and you are done. (Unlike in Windows, you have to first locate a suitable software and learn the interface yourself)
Another improvement is that a "xrdp" package is now stable enough to allow Windows's Remote Desktop client to connect to a Linux desktop. This is transparent to the Windows host. Together with the bundled "vino" package, I can now make use of a Remote Desktop client connected to the console GUI session of the linux host.
Next step: proftpd configuration, xrdp + Xvnc to enable connection to multiple GUI sessions.
