Answer to a email about 9750/D900K and Linux

I’m an application developer, developing mainly server applications and I have been searching for a multi core Notebook with a raid controller for a while. Since Linux is my preferred OS, my favorite setup is a Linux host with Windows and other OS’s running in VMWare identical to your setup.
My questions are:
•Did you have any problems installing Linux?
•Did you find drivers to all the devices? Do all work?
•Do you use raid?
•How is VMWare working with SMP?
Any information about your experience with the computer and Linux will be greatly appreciated.
I'm not the the only one using Linux on the Sager 9750 / Clevo D900K, BigTrouble77 is also using Linux on these laptops.
But I'll answer most of your questions.
- No I didn't have problems installing a 64bit release of Red Hat Enterprise Linux 4 on the 9750. It damm fast... I believe BigTrouble77 used Ubuntu or Debian.
- Most devices in the laptop work, the exceptions are : The USB Cam, and I don't expect it ever will. Those taiwanese USB Cams already have very weird drivers under Windows, so I don't think we will see them in Linux. The CF card works, but the SD didn't recognize my cards. I have not tested the Infra-Red stuff either. But the rest is good.
- No I'm not using the Hardware RAID on the system. I've put two Seagate Momentus 7200rpm 100GB SATA drives, and I use a combination of software-raid1 for the OS partitions /boot / /usr /opt /var and the top of /home. I've got two standalone NTFS partitions at the head of each disk for a small Windows XP install to play World of Warcraft. The rest of the disk is stripped under LVM for the vmware machines /home/vmimages /temp /opt. It's a complex file-system organisation to install, but I get the benefits of performance, space etc...
- I've create two vm's with SMP, they work fine, but not both at the same time, because of the performence impact. But what IS important for me is running RHEL4 in 64bit, and having inside VMware Workstation 5.5, Windows and Linux machines either in 32bit and 64bit at the same time. That's very neat. I use VMware ESX platforms at clients, so I can move systems from my laptop to major quad-dual-core opteron ESX servers.
Sure the 9750 is a heavy animal, but it's a true dual-core performer. For example. Compile the Linux Kernel 2.6.15 on a single core of the AMD X2 4800+ takes about 21 minutes, compile Linux kernel 2.6.15 with the 'make -j3' command (3 thread) and it goes down to about 7 minutes. That's speed increase for you. Take the AMD with the 1MB cache per core (4400, 4800 or FX60)
Hope this helps a bit.
