But the full whitepaper is no longer present on Dell's download site. Even finding the 1 page http://downloads.dell.com/manuals/common/Direct_from_Development_-_Balanced_Memory_on_2nd_Generation_AMD_EPYC_Processors_Reference_Guide.pdf Still links to the full whitepaper under a download URL that no longer works. Anyone know either where the full whitepaper can be found or what kind of performance penalty we're looking at for this type of NUMA memory config?
FWIW, i strongly deter any of my users from configuring a machine that's not fully "balanced". Unfortunately, that's hard here on the Epyc Gen II where you have to use 8 DIMMs and 8GB is the smallest. (so a 2P server has at least 128GB of RAM, even if you don't need it) Amazingly the site is not hiding dirindexes, so, just head on over to: https://downloads.dell.com/manuals/common/ Quality Control is Job None in the world today :-( (for renaming files and not validating links) How's this? https://downloads.dell.com/manuals/common/dellemc-balanced-memory-2ndgen-amd-epyc-poweredge.pdf The Epyc "Chiplet" arrangement makes things even more weird for configuring systems. I haven't read the WP yet, but thanks for pointing it out.
