Silicom Ltd. Connectivity Solutions Page 1 P4CG2I81 Dual port 100G Ethernet PCIe Card Dual port 100G Ethernet PCIe Gen 4.0 Server Adapter Intel® based Product Description Silicom’s P4CG2I81 100 Gigabit Ethernet PCI Express server adapters IS designed for Servers and high-end appliances. The Silicom 100 Gigabit Ethernet PCI Express Server adapters offer simple integration into any PCI Express X16 to 100Gigabit Networks. The performance is optimized so that system I/O is not the bottleneck in high-performance networking applications. The Silicom P4CG2I81 100 Gigabit Ethernet PCI Express server adapters is based on Intel E810-CAM2 Ethernet controller with fully integrated two 100G Ethernet Ports, enhanced programmable packet processing pipeline, virtualization (Enhanced SR-IOV support with up to 256 VFs, backward compatibility VF driver support), new features for the communications market (fine grained scheduler, transmit head drop support, adjustment of credits according to different headers, enhanced QoS, enhanced burst control) and RDMA (iWARP and RoCEv2). Silicom’s P4CG2i81 100 Gigabit Ethernet PCI-Express Server adapter is the ideal solution for implementing multiple network segments, mission- critical high-powered networking applications and environments within high performance servers. Key Features LAN and Virtualization Features:

  • 100Gbps throughput (each of Tx and Rx)
  • Parses up to 504B from packet header
  • 768 switch ports (VSIs)
  • Programmable forwarding rules
  • Virtualization o Host virtualization via VMQ and SR-IOV o 256 SR-IOV Virtual Functions o Stateless offloads for tunneled packets (network virtualization support) o Malicious VF protection
  • RDMA
