The Broadcom BCM957314A3143CC (Rev 18) is a high-performance, dual-port 25 Gigabit Ethernet (25GbE) Network Interface Card (NIC) built on the Broadcom NetXtreme-C series architecture. Designed for modern data centers, cloud infrastructure, and enterprise server environments, this PCIe 3.0 x8 adapter delivers ultra-low latency and high throughput over SFP28/SFP+ optical transceivers or Direct Attach Copper (DAC) cables.
Key Features & Specifications:
- Controller & Speed. Powered by the Broadcom BCM57314 controller supporting dual-port 10GbE and 25GbE full-duplex line rates.
- Host Interface. Eight-lane PCI Express (PCIe) Gen 3.0 x8 bus interface for high-bandwidth server integration.
- Connectivity. Two SFP28 cages backward-compatible with 10G SFP+ modules and copper DAC cables.
- Virtualization & Offloads. Features SR-IOV (up to 128 Virtual Functions), TruFlow™ intelligent flow processing, and hardware stateless offloads for VXLAN, NVGRE, Geneve, and GRE tunneling to reduce host CPU overhead.
- Data Center & Manageability. Supports Data Center Bridging (DCB: PFC, ETS, QCN, DCBx), jumbo frames up to 9 KB, and Broadcom TruManage™ with NCSI and MCTP over SMBus/PCIe VDM for seamless out-of-band server management.
