Hi,
Just seeing some nice 2 node HA cluster systems on the market, that have
HTB seemingly just by connecting a PCIe port directly between AMD Epyc
CPUs.
It occurred to me that 2 commodity motherboards could be connected by
crossover SlimSAS, OcuLink, MiniSAS HD, or any of the SFF-nnnn cables
used for PCIe. I think support of the BIOS would be required to
configure the PCIe port into NTB mode.
Has anyone run across this while working on Coreboot? It seems faster
and cheaper than Infiniband cards... and more available given pervasiveÂ
supply chain issues these days.
Regards,
Jeremy
