Minimum Hardware

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 (good through 12/2014)

Nodes must meet minimum CPU, RAM, and storage requirements using the following sliding window for accepted configurations:

 PCU CPU                        
Built-in, remote-access power-reset capability, accessible from PLC, such as IntelAMT, HPiLO, DellRAC, IPMIv2, etc.6x Intel Xeon E5 cores @ 2.2Ghz (or equivalent/higher) 24 GByte 2TB

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:
