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.
