A flexible
NIC with four
network ports
is used as an
example.
The four
network port
numbers are
as follows:
l 02/00/0
l 02/00/1
l 02/00/2
l 02/00/3
—
Note 1: B/D/F, Bus/Device/Function Number.
Note 2: ROOT PORT (B/D/F) indicates the bus number of a CPU internal PCIe root port.
Device (B/D/F) indicates the bus number (displayed on the OS) of an onboard or external
PCIe port.
Note 3: The PCIe slots that support full-height full-length PCIe cards are backward
compatible with full-height half-length or half-height half-length PCIe cards.
Note 4: The PCIe slots with the bus width of PCIe x16 are backward compatible with PCIe
x8, PCIe x4, and PCIe x1 cards.
Note 5: The power supply capabilities of all slots support PCIe cards of 75 W. The power
of a PCIe card depends on its model. For details about the supported PCIe cards, see
Huawei Server Compatibility Checker. For PCIe cards out of the Huawei Server
Compatibility Checker, contact your local Huawei sales personnel.
Note 6: Table 2-2 lists the default values of B/D/F. If CPUs are not in full configuration or
a PCIe card with a PCI bridge is configured, the values of B/D/F may differ.
Note 7: For a server with NVMe PCIe SSDs, a 2-slot riser module must be installed on the
I/O module and an NVMe PCIe SSD adapter can be installed only in slot 7.
PCIe GPU Configuration Rules
A GPU must be installed on a PCIe riser module.
