AI computing power
|
- Supports Ascend 910 B processor, with a maximum of 30 AI cores at 900 MHz per core and 256 TFLOPS computing power.
- Supports Ascend 910 A processor, with a maximum of 32 AI cores at 1.0 GHz per core and 256 TFLOPS computing power.
- Supports Ascend 910 Pro B processor, with a maximum of 30 AI cores at 1.15 GHz per core and 280 TFLOPS computing power.
|
NPU
|
- Eight Huawei Ascend 910 NPUs.
- 16 Huawei 64-bit TaiShan processor cores with a maximum frequency at 2.4 GHz.
- Three Hydra links forming two 4P Full Mesh links. The communication bandwidth between NPUs can reach 90 GB/s.
|
CPU
|
- Two Intel Cascade Lake processors.
- Up to 3.8 GHz frequency, 38.5 MB L3 cache, and three 10.4 GT/s UPI links.
- L2 cache added, with each core exclusively occupying 1 MB L2 cache.
|
Memory
|
- Up to 24 DDR4 DIMM slots, supporting RDIMMs.
- A maximum memory speed of 2933 MT/s.
- The capacity of a single DIMM can be 32 GB, 64 GB.
NOTE: DIMMs of different specifications (such as the capacity, bit width, rank, and height) cannot be installed on one server. That is, all DIMMs on one server must have the same part number.

Storage
|
Drive:
|
FlexIO card
|
An NPU supports a maximum of four FlexIO cards. Each FlexIO card provides the following network ports:
Two 100GE optical ports, supporting 100GE optical fibers or copper cables.
NOTE: - When a 100GE optical port supports a 100GE copper cable, the NPUs do not support auto-negotiation. In this case, the auto-negotiation function must be disabled on the peer device.
- The two 100GE optical ports of each FlexIO card are from different CPUs or NPUs. You are not advised to bind network ports. Network port binding will deteriorate performance.
|
PCIe slot
|
- Up to six PCIe 3.0 slots.
- PRM 1 supports:
- One FHFL PCIe 3.0 x16 slots (width: PCIe 3.0 x16)
- Two FHFL PCIe 3.0 x16 slots (width: PCIe 3.0 x8)
- PRM 2 supports:
- One HHHL PCIe 3.0 x16 slots (width: PCIe 3.0 x16)
- Two HHHL PCIe 3.0 x16 slots (width: PCIe 3.0 x8)
|
Port
|
- Two USB 3.0 ports and one DB15 VGA port on the front panel
- Two USB 3.0 ports, one DB15 VGA port, one RJ45 serial port, one RJ45 management network port, and two 10GE optical ports.
|
Fan module
|
- Eight hot-swappable fan modules in N+1 redundancy mode.
- Tolerating the failure of a single fan module.
NOTE: - Fan modules on the same server must have the same part number.
- When the fan modules work in N+1 mode, the maximum operating temperature supported decreases by 5°C.
|
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 Mbps RJ45 management network port.
|
Security
|
- Administrator password
- Secure boot and trusted boot
- TPM (available in and out of China)
- (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.
|
Graphics card
|
The mainboard integrates an SM750 graphics card, providing 32 MB memory and supporting a maximum resolution of 1920 x 1200 at 60 Hz with 16 M colors.
NOTE: - The maximum resolution 1920 x 1200 is supported only after the video card driver that corresponds to the server OS version is installed. Otherwise, only the default resolution of the OS is supported.
- If both the front and rear VGA ports are connected to monitors, only the monitor connected to the front VGA port is available.
