Supermicro was at FMS 2016, showing off some of their NVMe chassis:
The first model is the SYS-1028U-TN10RT+. This 1U chassis lets you hot swap 10 2.5" U.2 SSDs, connecting all lanes directly to the host CPUs.
Supermicro's custom PCB and interposer links all 40 PCIe lanes to the motherboard / CPUs.
Need more drives installed? Next up is the SYS-2028U-TN24R4T+, which uses a pair of PCIe switches to connect 24 U.2 SSDs to the same pair of CPUs.
Need EVEN MORE drives installed? The SSG-2028R-NR48N uses multiple switches to connect 48 U.2 SSDs in a single 2U chassis! While the switches will limit the ultimate sequential throughput of the whole package to PCIe 3.0 x40, we know that when it comes to spreading workloads across multiple SSDs, bandwidth bottlenecks are not the whole story, as latency is greatly reduced for a given workload. With a fast set of U.2 parts installed in this chassis, the raw IOPS performance would likely saturate all threads / cores of the installed Xeons before it saturated the PCIe bus!
More to follow as we wrap up FMS 2016!

Are you exaggerating?
p.s. Could you elaborate on the HBAs Supermicro are using?
If you look on the supermicro
If you look on the supermicro site they have a u.2 x2 to pcie 8x adapter best guess there using those but they are a bit proprietary in terms of firmware
Not HBA’s, these are
Not HBA's, these are switches. All SSDs are addressed by the CPU.
