PCI Express - stores and accesses Ethernet fabric connection information and packet data.SPI - includes 128Mb SPI Flash device (W25Q128JVSIQ
device by WINBOND-NUVOTON).
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 net­work scalability issues, it hides the TCP engines, placing higher loads on the host CPU. ConnectX-5 effectively addresses this by providing advanced NVGRE and VXLAN hardware offload­ing 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 hard­ware mechanisms, RoCE provides efficient low-latency RDMA services over Layer 2 and Layer 3 networks.
PeerDirect™ communication provides high efficiency RDMA access by elimi­nating unnecessary internal data copies between components on the PCIe bu (for example, from GPU to CPU), and therefore significantly reduces applica­tion run time. ConnectX-5 advanced acceleration technology enables higher cluster efficiency and scalability to tens of thousands of nodes.
Adapter functionality enabling reduced CPU overhead allowing more available CPU for computation tasks.

2 Interfaces

The adapter card includes special circuits to protect from ESD shocks to the card/server when plugging copper cables.
Each adapter card includes the following interfaces:
• “Ethernet SFP28 Interface”
• “
PCI Express Interface”
• “LED Interface”

2.1 Ethernet SFP28 Interface

The network ports of the ConnectX®-5 adapter card are compliant with the IEEE 802.3 Ethernet standards listed in Table 4, “Features,” on page 12. Ethernet traffic is transmitted through the cards' SFP28 connectors.
Interfaces

2.2 PCI Express Interface

The ConnectX®-5 adapter card supports PCI Express Gen 3.0 (1.1 and 2.0 compatible) through an x8/x16 edge connector. The device can be either a master initiating the PCI Express bus oper­ations, or a slave responding to PCI bus operations.
The following lists PCIe interface
• PCIe Gen 3.0 compliant, 2.0 and 1.1 compatible .5, 5.0, or 8.0 GT/s link rate x8/x16
