BIOS revision and settings
As BIOS revisions and settings depend on the chosen motherboard, no precise instructions can be given in a generic way. However, make sure to follow these guidelines:
Choose the latest stable public BIOS revision level available at the time of setting up the systems.
Start from the default parameters (optimised settings). Then make sure the following settings are chosen:
- Hyperthreading/symmetric multi-threading enabled
- Turbo mode (where applicable) enabled
- Console redirection enabled with the following parameters: port B, 9600 baud, no flow control, Terminal type VT100 8-bit, continue after POST enabled
- Quick boot disabled, quiet boot disabled, summary screen enabled
- After power failure: stay off
- Plug and Play O/S: enabled
- ECC event logging, PCI event logging enabled; NMI on these error types enabled
- Boot device priority: removable, CD-ROM, NICs via PXE, hard disk
Operating System
The standard operating system used for CERN benchmarking is 'Scientific Linux CERN 6.2 downloadable from:
http://linuxsoft.cern.ch/cern/slc6X/iso/SLC_6.2_x86_64_dvd.iso
or is available on 10.0.0.220 at /iso/SLC_6.2_x86_64_dvd.iso
File System Layout
The filesystem layout should be as such:
| Filesystem | Mounted On | Filesystem Type | RAID level | Size |
|---|---|---|---|---|
| /dev/md0 | /boot | Software RAID-1 | ext3 | 512MB |
| /dev/md1 | / | Software RAID-1 | ext3 | 20GB (may want to make this bigger) |
| /dev/md2 | /tmp | Software RAID-1 | ext3 | 5G |
| /dev/md3 | /var | Software RAID-1 | ext3 | 10GB |
| /dev/md4 | /usr/vice/cache | Software RAID-1 | ext3 | 5GB |
| /dev/md5 | /swap | Software RAID-1 | swap | same size as RAM in the system |
| /dev/md6 | /pool | Software RAID-0 | ext3 | all remaning available space on all available drives |
