Booting from USB or CD-ROM
Nodes should support booting from a USB 2.0 based flash key. For security, only use a USB key that has a physical write protect switch (e.g., Imation Pivot Flash, TwinMOS Mobile Disk Z4, or others). However, if your system does not support USB booting or you cannot find a write-protect USB, then as a minimum it must also have a CD-ROM drive that supports bootable CD.
Minimum Hardware Requirements
Nodes must meet minimum CPU, RAM, and storage requirements using the following sliding window for accepted configurations:
| | Until 12/31/2007 | 1/1/2008 to 12/31/2008 | 1/1/2009 to 12/31/2009 |
| PCU | Remote Access from PLC to service port (22, 23, 80, 443, 16992, etc) | Remote Access from PLC to service port (22, 23, 80, 443, 16992, etc) | Remote Access from PLC to service port (22, 23, 80, 443, 16992, etc) |
| CPU | Intel Pentium 2.4Ghz
AMD 2400+ | Intel Pentium 3.2Ghz,
AMD 3200+,
or 2.4GHz MultiCore/Dual Core | Intel Xeon 30x0 2.4Ghz (Mcore/Core2Duo) |
| RAM | 1 GByte | 4 GByte | 4 Gbyte |
| DISK | 180 GByte | 320 GByte | 500 GB
|
At least two nodes must meet the configurations mentioned in the table above. More are better. If you do not know whether your hardware meets the minimum requirements, or whether it is supported by Linux, we strongly recommend purchasing one of the known working hardware configurations listed below:
