Based on the Broadcom BCM57508 200GbE MAC controller with an integrated dual-channel 100GbE SFI transceiver, it delivers reliable 100GbE connectivity while supporting advanced virtualization and tunneling acceleration. Designed for QSFP56 environments, this NIC supports QSFP56, QSFP28, and QSFP+ optical modules as well as copper direct-attach cables, making it a flexible choice for upgrades, mixed-speed deployments, and scalable server builds. Key Benefits & Features Dual-port 100GbE connectivity: Built for high-throughput server uplinks using two QSFP56 ports for data center and cloud workloads. BroadSAFE security technology: Designed as an industry-focused secure PCIe adapter solution leveraging Broadcom BroadSAFE technology. SR-IOV virtualization at scale: Supports SR-IOV with up to 1K virtual functions (VFs) to increase VM density and reduce CPU overhead. TruFlow flow processing engine: Helps accelerate vSwitch and flow processing to improve efficiency in virtualized environments. Advanced tunnel and offload support: Supports VXLAN, NVGRE, Geneve, and GRE encapsulation/decapsulation with tunnel-aware stateless offloads. Ideal Use Cases 100GbE server uplinks in enterprise and cloud data centers Virtualization hosts requiring SR-IOV and vSwitch acceleration High-performance computing and low-latency east-west traffic RoCE-enabled environments for RDMA-based workloads Storage and network fabrics using QSFP56 DAC or optical connectivity Technical Specifications SKU: BCM957508-P2100G Ports: Dual-port QSFP56 Network Speed: 2 x 100GbE (supports 50G PAM-4, 25G NRZ, 10G NRZ signaling) Host Interface: PCI Express 4.0 x16 Controller: Broadcom BCM57508 200GbE MAC with integrated dual-channel 100GbE SFI transceiver Supported Media: QSFP56/QSFP28/QSFP+ optical modules and copper direct-attach cables Virtualization: SR-IOV up to 1K VFs, vSwitch acceleration, multiqueue, VMQ RDMA: RDMA over Converged Ethernet (RoCE) Jumbo Frames: Up to 9 KB Power Consumption: 16.0W typical (passive DAC), up to 22.0W max (optical transceiver) Operating Temperature: 0 to 55 Celsius Form Factor: PCIe add-in card, low-profile half-length (standard and low-profile brackets included) Upgrade to 100GbE Without Compromise Deploy the Broadcom BCM957508-P2100G for scalable 100GbE performance, secure virtualization, and modern offload acceleration.
