I am leaving boot on a non-RAID device, this build is for speed not reliability so RAID for boot is irrelevant.
I built the system like this
/dev/sda1 /boot

Then I built RAID 0 on sda2 and sdb2.

Revision as of 05:04, 22 February 2013

Laysan is my current desktop computer.

This is by far the fastest (and quietest) computer I have ever used or owned.

I had intended to build a server, then it got turned into my desktop instead. The server ended up being built later.

Components

Motherboard: ASUS P8B-M LGA 1155 Intel C204 Micro ATX Server Motherboard

CPU: Intel Xeon E3-1230 Sandy Bridge 3.2GHz LGA 1155 80W Quad-Core Server Processor BX80623E31230

RAM: 8GB x 2 Kingston 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1333 (PC3 10600) ECC Unbuffered Server Memory Model KVR1333D3E9SK2/8G

Drives:

  • Operating system and home directory on an OCZ Agility 3 240GB SATA III] MLC (SSD)
  • Data storage on a 2 TB WDC Caviar Black (SATA 2) WD2001FASS-0

DVD burner: TSSTcorp CDDVDW SH-222BB

Video: PNY VCQ2000D-PB Quadro 2000D 1GB 128-bit GDDR5 Workstation Video Card I wanted a workstation video card, as I want to do some OpenGL programming, and I work with ArcGIS software. This is the only component in this build that I would change; I would get a high end gaming board instead of a low end workstation board.

Monitors: Acer 23" and Acer 17".

Keyboard: IBM PS/2 Model M SpaceSaver (built in 1987)

Audio: This motherboard has no integrated audio so I use a NuForce UDAC 2 and a pair of Acoustic Research powered speakers.

Other: bT878 video capture card, an Osprey 210, that so far I have never used!

Case: Fractal Design Define Mini Black Micro ATX Silent PC Computer Case w/ USB 3.0 support and 2 x 120mm Fractal Design Silent Fans

Power supply: SeaSonic S12II 620 Bronze 620W ATX12V V2.3 / EPS 12V V2.91 80 PLUS BRONZE Certified Active PFC Power Supply

Operating system

Linux Mint 14

Operating system is split between a 240GB SSD and a 1TB HD. I had a RAID 0 setup with 2 SSD's but the (considerable) speed bump was not worth the pain to configure and maintain it.

On RAM fs are /tmp, /var/tmp, /var/run, /var/lock

Since the system has 16GB of RAM I am not worried about swap space. I put it in a swapfile on the 1TB drive. 

echo vm.swappiness = 0 > /etc/sysctl.d/swappiness.conf

# Make a 4 GB swapfile
sudo dd if=/dev/zero of=/var/swapfile1 bs=1024 count=4096k
sudo mkswap /var/swapfile1
sudo chmod 0600 /var/swapfile1

cat /etc/fstab 

# /etc/fstab: static file system information.
#
# Use 'blkid' to print the universally unique identifier for a
# device; this may be used with UUID= as a more robust way to name devices
# that works even if disks are added and removed. See fstab(5).

/var/swapfile1 none swap sw 0 0
#
# Move things to RAM DISK for speed
tmpfs /tmp     tmpfs defaults,noatime,mode=1777 0 0 
tmpfs /var/tmp tmpfs defaults,noatime,mode=1777 0 0
