What an excellent simple post. Amazing how our of sync, how ridiculous the situation is. The board real-estate for DIMMs is out of control. I'd say smaller form factors would be so excellent, but short of serious change it feels like an incommensurate ask, like it's not going to get us to really better. Yesterday there was an article on Intel's newest integrated silicon photonics, this time having some of the photonics on stacked chiplets on the chip[1]. It's a different sort of integration and micro-miniaturization, but feels very much the same. Not needing a big ole NIC, not needing to have extra, power sucking PCIe transcievers at each end, by moving capabilities onto the chip complex would be amazing. I'd love to see ultra-dense servers of the future where there are dozens of cpus on a sled, with basically just power & optical io feeding each chip. We've bounced off the "disaggregated rack" a couple times now, but it also feels like a major phase transition has been building for a while to.
