WinPE 的一點點筆記

雙機的話還有另一種方案，就是用兩顆 Xeon Scalable 或者蘇媽的 EPYC 也可以：

Well RAM is a topic on its own, to start with, the 2 cpu’s are split into domains (NUMA / SNC), so you really have 2 x 6 dimms, 6 for each CPU, they are not shared. Music services have their own cpu/dimms and the OS has its own cpu/dims. So its sort of a core and endpoint into a single machine going beyond just core allocations for individual processes.

The last experiment I've done, inspired by @austinpop and @romaz was to install HQplayer with affinities on one CPU and NAA with affinities to the other CPU. It's good to have two processors! I also created a loopback interface with ipv6. And I used ipv6 via the loopback interface to stream from the HQP to NAA. No upsampling, just using HQP as a bit perfect player. This brought the server that was sounding so great already to yet another level. Everything sounds so effortless now.

但他們的華碩 WS C621E SAGE 好像比較「落後」一點了：

超微的 Hyper DP Server board 則擁有（「變態」級數的）44 相供電，畢竟 H13DSH 理論上能夠支援兩顆 400W TDP 的 EPYC：

可惜電供方面則只能夠用官方提供的型號，而且只可以購買準系統，不知道需要等到何年何月才有機會單獨購買主機板：
