It can be operated w/o a host. It offers the ability to connect 16 lanes (or is it 32?) of PCIe Gen5. It has a 1 GbE management port, a BMC running OpenBMC, and a 400GbE NIC that does crypto offload.
The debug environment is FANTASTIC.. you can remote attach a gdb, set breaks, and step through bootup. It made it super easy to get our OS going on it (especially when I couldn't talk to the serial-on-lan port for a stupid reason, and could not get into the box.. I could at least use the debugger to verify we were booting).
