Re: Hardened Ethernet??
This is not just made up techno babble. Apeiron took the Layer-2 Enet protocol and added some of the features typically found in layer-3 or above, the loss-less characteristics needed for storage connectivity. Features such as re-transmission of packets, packet re-ordering, flow control (back-pressure) and the full data path is integrated in to the hardware vs. the software. This is where the term "hardened" comes from. The connectivity between the server and the integrated storage network has all HA qualities of Layer-3 and above without the latency. This is where a lot of the Apeiron IP is: Apeiron is simply moving the PCIe TLP's via a hardened layer-2 tunnel to the integrated switching.
