Description

Net Card 2 for H-series (H3/H2 Net Card 2)

The new Net Card 2 has the same physical form factor and interface method as the original Net Card, but the NIC chipset has changed from Realtek’s RTL8125B to Intel’s I226-V. There is no significant difference in network performance or driver functions, but it shows better compatibility with Hyperviser-based virtual machines such as ESXi.

The Net Card 2 for H-series brings 4 additional 2.5 GbE Ethernet ports for an incredible low price. It is compatible with the ODROID-H series. Using a H2+, H3, H3+ you end up with a total of 6 x 2.5 GbE Ethernet ports. With the H2 and H2 rev. B you get 2 x 1 GbE and 4 x 2.5 GbE Ethernet ports.

ODROID-H series with the Net Card2 brings new capabilities and applications.

Implementing a DIY router or gateway for up to 5 (H2+/H3/H3+) clients at 2.5 GbE speed on each port.
Setup a DIY server, e.g. a NAS, for up to 6 (H2+/H3/H3+) clients at 2.5 GbE speed on each port.
Brings 2.5 GbE Ethernet connectivity to the H2 and H2 rev. B boards making them able to talk at full speed (usually 2.35 Gbits/sec) with H2+/H3/H3+ boards.

Results
As shown above chart, the more executing iperf3 the more CPU usage like being step by step. One to six ethernet ports are executed 30 seconds between them in order. Running 300 seconds for each client. so all six clients are running has done in 480 seconds. The last port execution led CPU Usage to go up to 100% in Reverse mode. In this stage, the network throughput shows unstable to little down speeding at approximately 1.61 Gbits/sec to 2.01 Gbits/sec.

Conclusion

A H3(+) can therefore provide excellent support for parallel clients with enough remaining CPU resources to proceed with computation and disk IO.

In other words, the Net Card 2 for H-series brings significant added value to a H3/H3+ based NAS or Router/Gateway solution where parallel clients can enjoy the full 2.5 GbE speed independently from each other. All with a very low cost network card 🙂

Warning: Have to flash GLK-ESF BIOS to use Net Card properly.
