Physical dimensions

Characteristic Description
PCIe length 1/2-length
PCIe height Full-height
PCIe width Single-slot

This list shows the PCIe standard dimensions:

  • 1/2-length: 167.65 mm (6.600 inches)
  • Full-height: 111.28 mm (4.381 inches)

Electrical rating

This table shows the power consumption for an NT100A01-NEBS SmartNIC including 4 pluggable modules.

Port Speed Power consumption [in W]
NT100A01-NEBS 4 × 1 Gbit/s 30
NT100A01-NEBS 4 × 10 Gbit/s 38
NT100A01-NEBS 4 × 25 Gbit/s 44

Power is measured with capture of a stream with 80% load of 300-byte frames. A sustaining load of 80% with 300-byte frames is representative for maximum real-life scenario. The actual power consumption depends on the FPGA software payload.

The SmartNIC is Class III equipment for supply by SELV circuits only.

Port numbers

Characteristic Description
Port numbers 0, 1, 2 and 3
