BlueField-3 DPUs Overview
BlueField-3 DPUs includes one NVIDIA BlueField-3 SuperNIC and one BlueField-3 DPU supporting Ethernet and InfiniBand server connectivity. Both models use QSFP112 network interfaces, PCIe Gen5 x16 host connectivity, integrated BMCs, onboard DDR5 memory, and crypto-disabled configurations. The B3140H is an E-Series HHHL SuperNIC with one 400Gb/s port and eight Arm cores, while the B3220 is a P-Series FHHL DPU with two 200Gb/s ports, 16 Arm cores, and an optional additional PCIe x16 connection. They address AI networking and infrastructure processing requirements in data center servers.
B3140H is a single-slot HHHL BlueField-3 E-Series SuperNIC with one QSFP112 port supporting 400GbE by default or NDR 400Gb/s InfiniBand. It uses a PCIe Gen5 x16 host interface and integrates eight Arm cores, 16GB of onboard DDR5 memory, and a BMC. This crypto-disabled configuration supports high-speed RoCE and InfiniBand connectivity between servers and is supplied with tall and short brackets.
B3220 is a single-slot FHHL BlueField-3 P-Series DPU with two QSFP112 ports supporting 200GbE by default or NDR200 InfiniBand per port. It connects through PCIe Gen5 x16 and supports an optional additional PCIe x16 interface through an auxiliary card and cable assembly. The DPU integrates 16 Arm cores, 32GB of onboard DDR5 memory, and a BMC. This crypto-disabled model is supplied with a tall bracket and supports infrastructure processing for networking, storage, security, and management services.
FAQ
- What are the key port, compute, memory, and form-factor differences between the B3140H and B3220 models in the BlueField-3 DPUs category?
The B3140H is an E-Series HHHL SuperNIC with one 400Gb/s-capable QSFP112 port, eight Arm cores, and 16GB DDR5. The B3220 is a P-Series FHHL DPU with two 200Gb/s-capable QSFP112 ports, 16 Arm cores, 32GB DDR5, and an optional additional PCIe x16 connection.
- Which Ethernet and InfiniBand operating modes are available through the single QSFP112 port on the B3140H BlueField-3 SuperNIC?
It supports 400GbE by default or NDR 400Gb/s InfiniBand. The B3140H also supports 200/100/50/25/10GbE and the listed NDR200, HDR, HDR100, EDR, FDR, and SDR InfiniBand modes through its single QSFP112 port.
- How are the two QSFP112 network ports on the B3220 configured for Ethernet and InfiniBand server connections?
Each port supports 200GbE by default or NDR200 200Gb/s InfiniBand. The B3220 also supports 100/50/25/10GbE and the listed HDR, HDR100, EDR, FDR, and SDR InfiniBand rates through its dual-port QSFP112 interface.
- Can the B3220 provide an additional PCIe connection beyond its primary PCIe Gen5 x16 host interface?
Yes. The B3220 supports an optional additional PCIe x16 Gen4/Gen5 connection through a compatible auxiliary passive card and cable harness. This option can provide Socket-Direct or downstream-port connectivity, depending on the auxiliary configuration.
- How much Arm processing capacity, onboard DDR5 memory, and management hardware do the B3140H and B3220 provide?
The B3140H provides eight Arm cores, 16GB onboard DDR5, and an integrated BMC. The B3220 doubles the resources to 16 Arm cores and 32GB onboard DDR5 while also including an integrated BMC.
- What server slot and bracket configurations are required for installing the B3140H and B3220 adapter cards?
The B3140H is a single-slot HHHL card supplied with tall and short bracket options. The B3220 is a larger single-slot FHHL card supplied with a tall bracket, so the server chassis must accommodate the corresponding card height and length.
- What server power connections are required when deploying the B3140H and B3220 BlueField-3 cards?
The B3140H requires at least 75W supplied through the PCIe x16 interface. The B3220 requires a supplementary 8-pin ATX power connection in addition to its PCIe slot connection.
- Are the listed B3140H and B3220 configurations in the BlueField-3 DPUs category crypto-enabled?
No. The listed B3140H and B3220 configurations are crypto-disabled versions. Both configurations still include their specified Arm processors, onboard DDR5 memory, QSFP112 network interfaces, PCIe Gen5 x16 connectivity, and integrated BMC.
