• When the server is equipped with Kunpeng 920 5220 or Kunpeng 920 3210 processors, it supports up to 16 DDR4 RDIMM slots.
• Maximum memory speed: 2933 MT/s
• Capacity of a single DIMM: 16 GB, 32 GB, 64 GB, or 128 GB

Storage

Drive:

• The server supports a variety of drive configurations. For details, see Table 2-7.
• The server supports hot-swap of a single drive.

RAID controller card:

• Supports a variety of RAID controller cards. Use the Computing Product Compatibility Checker to obtain information about the specific RAID controller cards supported.
• Provides a supercapacitor to protect cache data from power failures, and supports RAID level migration, drive roaming, self-diagnosis, and web-based configuration. For details about the RAID controller card, see the Huawei Server RAID Controller Card User Guide (Arm).

FlexIO card

A maximum of two FlexIOs. FlexIOs provide the following network ports:

• Four GE electrical ports, supporting PXE
• Four 25GE/10GE optical ports, supporting PXE
  NOTE:

  Different optical modules can be used to implement autonegotiation between 25GE and 10GE.

PCIe slots

• Supports a maximum of nine PCIe 4.0 slots, among which one is a PCIe slot dedicated for a screw-in RAID controller card, and the other eight are for PCIe cards. The specifications of PCIe 4.0 slots are as follows:

  I/O modules 1 and 2 provide the following PCIe slots:

  • Two standard full-height full-length PCIe 4.0 x16 slots (width: PCIe 4.0 x8) and one standard full-height half-length PCIe 4.0 x16 slot (width: PCIe 4.0 x8)
  • One standard full-height full-length PCIe 4.0 x16 slot and one standard full-height half-length PCIe 4.0 x16 slot (width: PCIe 4.0 x8)

  I/O module 3 provides the following PCIe slots:

  • Two standard full-height half-length (FHHL) PCIe 4.0 x16 slots (width: PCIe 4.0 x8)
  • One standard FHHL PCIe 4.0 x16 slot
• Supports Huawei PCIe SSD cards to improve I/O performance for search, cache, and download services.
• Supports Huawei AI accelerator cards to implement fast and efficient image identification, processing, and inference.
  NOTE:

  For details about the PCIe cards supported by the Atlas 800 inference server (model 3000), use the Computing Product Compatibility Checker.

Port

• Front panel: two USB 3.0 ports and one DB15 VGA port

• Rear panel: two USB 3.0 ports, one DB15 VGA port, one RJ45 serial port, and one RJ45 management network port

Fan module

System management

Huawei iBMC supports Intelligent Platform Management Interface (IPMI), Serial over LAN (SOL), KVM over IP, and virtual media, and provides one 10/100/1000 Mbit/s RJ45 management network port.

Security

• Administrator password
• (Optional) Front bezel
  NOTE:

  The front bezel is installed on the front panel and comes with a security lock to prevent unauthorized operations on drives.

GPU

The video processor integrated on the iBMC management processor provides 32 MB memory and supports a maximum resolution of 1920 x 1080 at 60 Hz with 16 M colors.
