The work and investment to turn that 4U deployment into two 2U deployments sounds like a far more realistic and effective way to go about the problem.

The point is that the capacity does not exist, hence these patches being shot down by kernel maintainers for being fundamentally broken.
Also, what are the real-world performance improvements of these memory hacks? Adding another COTS box next to the one already deployed should double capacity straight away.
- rcxdude 3y agofrom what I can see the kernel developers don't like the particular means used in the patch, there's no fundamental objection to the idea of enabling device-to-device DMA as a performance optimisation.
