Broadcom BCM957504-P425G. Asic BCM57504. 4x SFP28 25GbE. PCIe x4.

The Broadcom BCM957504-P425G is a four-port PCI Express 4.0 x16 25 Gb/s Network Interface Card that supports SFP28/SFP+ optical modules and copper straight-through cables. The card uses the Broadcom BCM57504 100GbE MAC Controller with integrated four channel 25GbE SFI Transceiver.

Based on Broadcom's 10/25/50/100/200G scalable Ethernet controller architecture, the NetXtreme®-E Series P425G 4x25G PCIe NIC is designed to create highly scalable and feature-rich network solutions in enterprise servers and networks across cloud scale and storage applications, including high-performance computing, telecommunications, machine learning, storage disaggregation, and data analytics.

The P425G 4x25G PCIe NIC builds on the success of the widely deployed NetXtreme E-Series architecture by combining a high-bandwidth Ethernet controller with a unique set of highly optimized hardware acceleration engines to improve network performance and improve server efficiency.

Driven by the growing need for increased server bandwidth and storage capacity to support new and emerging applications, enterprises, telcos, and cloud providers are modernizing their data centers by adopting the latest technologies. latest networking technologies such as server virtualization and NVMe-oF™. The resulting expansion in data volumes increases server-to-server traffic and CPU loads for network tasks.

With its market-leading hardware acceleration technologies, the NetXtreme-E Series P425G 4x25G PCIe NIC addresses these performance and service demands of large-scale data center networks with high performance and advanced stream processing. Features like TruFlow™ increase virtual machine density by up to 50%, freeing up more CPU cycles for additional virtual machines.

On-chip tunneling protocol processing for Geneve, VXLAN, and NVGRE provides up to a 5x performance boost while reducing CPU utilization by up to 90 percent compared to software-only solutions. NetXtreme-E series solutions also support advanced network technologies such as RoCE, SDN and NFV to facilitate data network management and enable service provider solutions.
