PCIe Mapping

{{ $t('productDocDetail.updateTime') }}: 2026-01-05

Description

HCI supports two types of PCIe devices: management NIC and cryptographic card. They can be passed through to VMs directly or after virtualization.

Precautions

  1. The PCIe device list displays all PCIe devices on a host. The devices associated with VMs cannot be enabled, disabled, or edited. In addition, only the following devices that support splitting can be edited.

Device Type

Number of Virtual Devices

Device Model

Cryptographic card

• SYD: 32

• Sansec: 64

• SYD: SYD1308-G

• Sansec: SJK1727 V2.0, SC62-X4AN, X4BN, and X4CN

NIC

• Virtual function (VF): 16

• Physical function (PF): 8 (supported by SFC X2522 only)

• Intel: X710 and X722

• Mellanox: CX4121A and SFC X2522

  1. If a device is disabled, the mode will be reset.

Prerequisites

You have enabled the input-output memory management unit (IOMMU) or system memory management unit (SMMU) of the host.

Steps

Go to Nodes > Nodes, hover your mouse over a host and click Summary. On the page that is displayed, click the PCIe Devices tab, where you can edit, enable, and disable a device, and view subdevices.

• For cryptographic cards, Mode can be set to Passthrough or SR-IOV.

• For NICs, Mode can be set to SR-IOV and Type can be set to VF or PF.

PFs support all PCIe capabilities and they can be discovered, managed, and configured in the same way as PCI devices.

VFs, which are virtualized from PFs, support lightweight PCIe capabilities and can process I/O requests only. Once SR-IOV is enabled, the PCI configuration space of each VF can be accessed using the bus, device, and function numbers of PF, and each VF possesses a PCI memory space to map its register set.
