● A PCIe slot that supports a full-height full-length PCIe card is backward compatible with
a full-height half-length or half-height half-length PCIe card. A PCIe slot that supports a
full-height half-length PCIe card is backward compatible with a half-height half-length
PCIe card.
● A PCIe slot that supports a PCIe x16 card is backward compatible with a PCIe x8, x4, or
x2 card. A PCIe slot that supports a PCIe x8 card is backward compatible with a PCIe x4,
or x2 card.
● All slots support PCIe cards of up to 75 W. The power of a PCIe card varies depending
on its model. For details about supported PCIe cards, use the
Compatibility Checker. For PCIe cards not listed by the Intelligent Computing
Compatibility Checker, contact the local Huawei sales personnel to submit the
compatibility test requirements.
● When two 2.5-inch drives are installed in I/O module 1, this module also supports a
PCIe x16 riser card in slot 3.
● B/D/F indicates Bus/Device/Function Number.
● ROOT PORT (B/D/F) indicates the B/D/F of a CPU internal PCIe root port. Device
(B/D/F) indicates the B/D/F (displayed on the OS) of an onboard or external PCIe port.
● The values of B/D/F listed in this table are default ones. If PCIe cards are not fully
configured or a PCIe card with a PCI bridge is configured, the values of B/D/F may
differ.
● Atlas 300 accelerator cards are supported and dedicated riser cards are required. For
details, see Intelligent Computing Compatibility
shows the components of the 2180.
