2U4 server node


Intel® C622


Supports one or two processors.

  • Intel® Xeon® Scalable (Skylake and Cascade Lake) processors
  • Built-in memory controller and six memory channels
  • Built-in PCIe controller, supporting PCIe 3.0 and 48 lanes per processor
  • Two UPI buses between processors, providing up to 10.4GT/s transmission per channel
  • Up to 28 cores (2.5 GHz)
  • Max. 3.8 GHz (four cores)
  • Min. 1.375 MB L3 cache per core
  • Max. 205 W TDP

The preceding information is for reference only. Use the Intelligent Computing Compatibility Checker to obtain specific information.


Supports 16 memory modules of the following types:

  • Up to 16 DDR4 memory modules
  • Max. 2933 MT/s memory speed
  • RDIMM and LRDIMM support
  • The DDR4 memory modules of different types (RDIMM and LRDIMM) and specifications (capacity, bit width, rank, and height) cannot be used together.

The preceding information is for reference only. Use the Intelligent Computing Compatibility Checker to obtain specific information.


Supports a variety of drive configurations. For details, see Drive Configurations.

  • Supports two M.2 SSDs.
    • The M.2 SSD module is used only as the boot device when the OS is installed. Small-capacity (32 GB or 64 GB) M.2 SSDs do not support logging due to poor endurance. If a small-capacity M.2 SSD is used as the boot device, a dedicated log drive or log server is required for logging. For example, you can dump VMware logs in either of the following ways:
    • The M.2 SSD cannot be used to store data due to poor endurance. In write-intensive applications, the M.2 SSD will wear out in a short time.

      Use enterprise-level high endurance (HE) SSDs or HDDs for data storage.

    • The M.2 SSD is not recommended for write-intensive service software due to poor endurance.
    • Do not use the M.2 SSD as the cache.
  • Supports hot swap of SAS/SATA drives.
  • Supports a variety of RAID controller cards. Use the Intelligent Computing Compatibility Checker to obtain information about the specific RAID controller cards supported.
    • The RAID controller card supports RAID configuration, RAID level migration, and drive roaming.
    • The RAID controller card does not occupy a standard PCIe slot.

    For details about the RAID controller card, see Huawei V5 Server RAID Controller Card User Guide.


Supports LOM.

  • Supports two 10GE optical ports and two GE electrical ports via the NIC chip integrated on the mainboard.
  • The LOM ports support NC-SI, WOL, and PXE.
  • The electrical LOM ports cannot be connected to PoE devices (such as a switch with PoE enabled). Connecting a LOM port to a PoE device may cause link communication failure or even damage the NIC.
  • Forcibly powering off a server will cause intermittent NC-SI disconnection and disable the WOL function of the LOM ports. To restore the NC-SI connection, refresh the iBMC WebUI.

I/O expansion

3 PCIe 3.0 slots:

  • One slot dedicated for a RAID controller card and two for standard PCIe cards.

    For details, see PCIe Slots and PCIe Slot Description.

  • Support Huawei proprietary PCIe SSD cards to bolster I/O performance for applications such as searching, caching, and download services.

The preceding information is for reference only. Use the Intelligent Computing Compatibility Checker to obtain specific information.


Supports a variety of ports.

  • Ports on the front panel:
    • One universal connector port
    • One system management port
    • Two GE electrical ports
    • Two 10GE optical ports
  • Built-in ports:
    • 2 SATADOM ports

Video card

An SM750 video chip with 32 MB display memory is integrated on the mainboard. The maximum display resolution is 1920 x 1200 at 60 Hz with 16 M colors.


The integrated video card can provide the maximum display resolution (1920 x 1200) only after the video card driver matching the operating system version is installed. Otherwise, only the default resolution supported by the operating system is provided.

System management

  • UEFI
  • iBMC
  • NC-SI
  • Integration with third-party management systems

Security features

  • Power-on password
  • Administrator password
  • TPM (only outside China)
  • Secure boot
