The following illustration identifies the main components of the PCIe Expansion Node.


Graphic illustrating the main components of the PCIe Expansion Node
  • System board
    The system board executes all the major logic functions of the PCIe Expansion Node.
  • Interposer cable
    The interposer cable connects the PCIe Expansion Node to a supported host compute node.
  • Full-height PCIe riser
    The PCIe risers connect the PCIe adapters to the PCIe Expansion Node system board. The full-height PCIe riser has two slots for full-height PCIe adapters and is encased in a mechanical structure that supports the adapters.
  • Low-profile PCIe riser
    The PCIe risers connect the PCIe adapters to the PCIe Expansion Node system board. The low-profile PCIe riser has two slots for low-profile PCIe adapters and is encased in a mechanical structure that supports the adapters.
  • I/O expansion adapters
    The PCIe Expansion Node system board includes two 16x PCIe generation 2 connectors to support up to two I/O expansion adapters.
