- The U250 and U280 servers—as well as the Versal server—are virtualized.
- Not all servers in the U250 cluster support the Vivado workflow (as they do not have a USB - JTAG connection). The same is true for the Versal server.
- None of the QSFP28 FPGA interfaces are directly connected to other FPGAs—in a point-to-point topology—but to the corresponding leaf switch.
