This is Siena-based server AS-1115SV-WTNRT. Siena has 96 PCI Gen 5 lanes and it is amazing how much connectivity Supermicro managed to fit into this 1U server. It has 40 PCIe Gen 5 NVMe lanes for hot swap storage with two of the MCIO headers being hybrid to support to support SATA or SAS disks as well. This means no matter what disks you fill in front of the server, you will have more than enough bandwidth for line rate connectivity. Most impressive bit of I/O is actually around the rear where there are three full x16 PCIe Gen 5 slots. Supermicro managed to connect all 96 lanes from the Siena CPU directly to PCIe I/O devices. The density of this serer is impressive in terms of storage and general I/O and even more impressive what kind of storage bandwidth is available.
