Each node includes a Supermicro Micro-LP expansion module providing two LAN connections.
Currently, there are four supported for this system.
One Micro-LP PCIe 4.0 x8 slot
One M.2 PCIe 4.0 x4 slot with SATA3 support, M-Key 2280/22110
Two NVMe U.2 PCIe x4 slots via the backplane
The Micro-LP expansion module is inserted into a riser card and secured to two brackets as
