Broadcom BCM957508-P2100G Dual-Port 100GbE Network Interface Card

High-Density 100GbE Server Networking with Broadcom Performance

The Broadcom BCM957508-P2100G is a dual-port 100GbE PCI Express 4.0 x16 network interface card built for modern data center servers, virtualization stacks, and high-throughput storage fabrics. 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
