The PCIe x16 Gen 6 host interface board (OSS-638) with PCIe Copprlink cable connectors provides a high-speed, flexible, multi-funciton PCIe cable link using PCI-SIG compliant external cables and internal MCIO cable interfaces. The HIB 6310 supports a so,ware transparent path from a host’s root complex to multiple endpoints. The multi-port approach allows for a single x16 server slot to scale out to OSS PCIe 5.0 and 6.0 expansion systems while providing internal RDMA connectivity to NVMe drives, GPUs, FPGAs and industry leading accelerators.
