Support for 25GbE is available on ExaNIC X25

Happy to share the news of true support for 25GbE environments. With a recent firmware release, true 25GbE support is coming to the ExaNIC family. This enables the NIC to choose to run either 10GbE or 25GbE modes.

How does this affect bandwidth? With PCIe Gen3 we have about 60Gbits bandwidth available and yet we do see 2 ports maxing out the 25GbE available (50Gbps total)
