33 lane, 9 port, PCI Express Gen3 ExpressFabric Platform

Currently Viewing:

Broadcom has extended the reach of PCIe for use as a fabric for data center and cloud computing through its ExpressFabric initiative and platform of hardware and software. ExpressFabric can eliminate expensive bridging devices within the rack, such as adapter cards that translate native PCIe to Ethernet and back to PCIe. Yet ExpressFabric works seamlessly with other standards used within the rack and in rack-to-rack connectivity.
The industry-first ExpressFabric platform enables high performance, low latency, scalable, cost-effective fabric capabilities based on Gen3 PCI Express. The platform provides the ability to share I/O with standard SR-IOV or multifunction devices, and to enable multiple hosts to reside on a single PCIe-based network using standard PCIe enumeration – a capability not previously available on PCIe devices. The hosts communicate through Ethernet-like DMA, and do so using standard hosts, end-points, and application software.
