• Kunpeng 920 3210 processor: 2 x 24 cores @ 2.6 GHz

Cache

Each core integrates a 64 KB L1 instruction cache, a 64 KB L1 data cache, and a 512 KB L2 cache.

The L3 cache is 24 MB to 64 MB (1 MB/core).

Memory

• When the server is equipped with Kunpeng 920 7260 or Kunpeng 920 5250 processors, it supports up to 32 DDR4 RDIMM slots.
• 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
• Protected with ECC, SEC/DED, SDDC, and patrol scrubbing
• Capacity of a single DIMM: 16 GB, 32 GB, 64 GB, or 128 GB

Storage

SAS, SATA, and NVMe drives:

• For detailed configurations, see Drive Numbers.
• Drives are hot-swappable.

RAID controller cards:

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

FlexIO card

One or two FlexIO cards. A FlexIO card provides the following network ports:

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

  Different optical modules can be used for auto-negotiation between 25GE and 10GE.

PCIe slot

• A maximum of nine PCIe 4.0 slots: one for a RAID controller card and eight 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 PCIe 4.0 x16 slots (width: PCIe 4.0 x8)
  • One standard full-height half-length PCIe 4.0 x16 slot
• The PCIe expansion slots fully support Huawei proprietary PCIe SSD cards, which bolster I/O performance for applications such as search, cache, and download.
• The PCIe slots support Huawei-developed Atlas 300 AI accelerator cards to implement fast and efficient processing and reasoning, and image identification and processing.

Port

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

• Two USB 3.0 ports, one DB15 VGA port, one RJ45 serial port, and one RJ45 management network port on the rear panel

Fan module

Four hot-swappable fan modules, providing protection against single-fan failure

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
• Front bezel (optional)
  NOTE:

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