Data Interfaces
The data interfaces use OSFP connectors. The full list of interfaces per system is provided in
Each OSFP port consists of 2 logical InfiniBand ports, and can be connected with OSFP cable or
connector for 40/56/100/200/400 Gb/s. The system offers Class 8 (17W) OSFP112 transceivers
support.
Speed
InfiniBand speed is auto-adjusted by the InfiniBand protocol. NVIDIA systems support QDR/FDR/EDR/
HDR/NDR InfiniBand.
FDR is an InfiniBand data rate, where each lane of a 4X port runs a bit rate of 14.0625Gb/s
with 64b/66b encoding, resulting in an effective bandwidth of 56.25Gb/s.
EDR is an InfiniBand data rate, where each lane of a 4X port runs a bit rate of 25Gb/s with
64b/66b encoding, resulting in an effective bandwidth of 100Gb/s.
HDR is an InfiniBand data rate, where each lane of a 4X port runs a bit rate of 50Gb/s with
64b/66b encoding, resulting in an effective bandwidth of 200Gb/s.
NDR is an InfiniBand data rate, where each lane of a 4X port runs a bit rate of 100Gb/s with
64b/66b encoding, resulting in an effective bandwidth of 400Gb/s.
RS232 (Console)
The Console port labeled “
” is an RS232 serial port on the front side of the chassis that is
used for initial configuration and debugging. Upon first installation of the system, you need to
