It's take two for the PowerNode3. That's two 1-GHz PowerPC G4 7457 processors with 2 Mbytes of RAM each. It has PCI Mezzanine Card (PMC) slots along with two for Gigabit Ethernet. Three 4× high-speed links connect to the P0 backplane for PICMG 2.17 support. Even with all of these features, the PowerNode3 draws only 30 W of power in the dual-processor configuration. This system from Thales Computers comes with the PowerLine4 toolkit, which supports LynuxWorks and VxWorks. Pricing starts at $5870.
