A standard InfiniBand data rate, where each lane of a 4X port runs a bit rate of
25.78125Gb/s with a 64b/66b encoding, resulting in an effective bandwidth of 100Gb/s.
PCI Express - stores and accesses InfiniBand and/or Ethernet fabric connection information and packet data. SPI - includes 128Mb SPI Flash device (W25Q128FVSIG by WINBOND­NUVOTON).FRU EEPROM capacity is 2Kb.
In order to better scale their networks, data center operators often create overlay networks that carry traffic from individual virtual machines over logical tunnels in encapsulated formats such as NVGRE and VXLAN. While this solves net work scalability issues, it hides the TCP packet from the hardware offloading engines, placing higher loads on the host CPU. ConnectX-5 effectively addresses this by providing advanced NVGRE and VXLAN hardware offload ing engines that encapsulate and de-capsulate the overlay protocol.
ConnectX-5, utilizing IBTA RDMA (Remote Data Memory Access) and RoCE (RDMA over Converged Ethernet) technology, delivers low-latency and high­performance over Band and Ethernet networks. Leveraging data center bridging (DCB) capabilities as well as ConnectX-5 advanced congestion control hard ware mechanisms, RoCE provides efficient low-latency RDMA services over Layer 2 and Layer 3 networks.

1.4 Multi-Host Technology

ConnectX®-5 adapter card specifically designed for supported servers (as described in Section
3.1) implements Multi-Host technology to deliver direct and independent PCIe connections to
each of the four CPUs in the server. The ConnectX-5 PCIe x16 interface is separated into four independent PCIe x4 interfaces. Each
interface is connected to a separate host with no performance degradation. Connecting server CPUs directly to the network delivers performance gain as each CPU can send
and receive network traffic independently without the need to send network data to other CPUs using QPI bus.
