  • The B/D/F (Bus/Device/Function Number) is the default value when the server is fully configured with PCIe devices. The value may differ if the server is not fully configured with PCIe devices or if a PCIe card with a PCI bridge is configured.
  • The PCIe x16 slots are backwards compatible with PCIe x8, PCIe x4, and PCIe x1 cards and are not forwards compatible. That is, the bandwidth of a PCIe slot cannot be lower than the bandwidth of the PCIe card.
  • If two front 2.5-inch drives are configured, slots 1 and 2 are unavailable.
