The technology innovation of ExpEther expands the power of the PCI Express switch beyond the computer chassis via Ethernet without modification of existing hardware and software. ExpEther 40G devices delivers a compelling solution for real-time Big Data processing and other data center workload acceleration. It does so by enabling the connection of GPGPU, NVMe SSD, or FPGA-based accelerators via an Ethernet connection. Please visit the [ExpEther consortium](http://www.expether.org/){{< externallink >}} This Host-Bus adapter is used to connect the ExpEther 40G I/O Expansion Unit (N8141-80F, N8141-81F) to a host server vi an Ethernet. Please see the material of the I/O Expansion Unit.
