There are already a lot of OCP 3.0 network cards, but the price is slightly higher, but compared to the switch, it is still much cheaper.

Now you can have a 10G network card, but they are all older models, I found that the OCP 2.0 network card also has relatively new chip specifications, such as 10/25G general specifications, I don't know if you can get on the 25G network card??

In addition, OCP 2.0 seems to belong to the elimination of the standard, the new is the 3.0 specification size, I don't know the developer or manufacturer of R86S, whether there is a plan to use OCP 3.0 in the future??

In addition, these are server type network cards, and the drivers are generally updated quickly, and the newly released Linux Kernel will bring the drivers of these network cards, because they are not unpopular network cards, and they are supported by manufacturers behind them.
It's useless, two 10 Gigabit + 1X nvme already occupies all the PCI-e lane bandwidth of the processor, which is already the upper limit.
However, it was found that the CPU specifications currently used are not very powerful, and there is only PCIe x8 bandwidth in total, and I don't know how many Lanes are used by the above two network cards, x4 can be used, x8 is not good.
