HP DL585 G7 Hypertransport links between CPUs -

[David Bonnie]

I can't seem to find a solid answer to this anywhere for a 4P system with 6176SE CPUs.

Some diagrams show the CPUs being linked together by dual 8 bit connections (so each link in a 4P system is the full 10.4 GB/s at HT3.0 speeds). Other diagrams show the connections being dual 8 bit for the connections from CPU1->CPU2, CPU1->CPU3, CPU2->CPU4, and CPU3->CPU4 while the connections from CPU1->CPU4 and CPU2->CPU3 being only a single 8 bit link.

Anyone have a concrete answer on this? It's frustrating that the documentation from AMD for a 4P system doesn't line up with any of the other documentation I can find.

Any help would be extremely appreciated!!!

That diagram doesn't answer my question...
