no Epyc
Sort of interesting to see such a startup seemingly not wanting to use the new AMD server chips with their massive PCIe lanes for the NVMe connections. Looking at Intel's site the E8 recommended CPU has only 12 cores/ 48 lanes (I am far from an expert but have read in many cases several lanes on Intel systems are provided by the chipset not by the CPU and thus is far less ideal performance wise).
I'd almost wager having a single 32 core 128-lane Epyc CPU with 128 lanes would be far better than two 12 core / 48 lane chips.
Epyc doesn't particularly excite me personally for my vmware workloads, but for NVMe storage systems it sounds pretty ideal.
