Dual Port Fiber SFP+ 25 Gigabit Ethernet PCI Express GEN3 Server Adapter Broadcom® BCM57304 Based

Silicom’s 25 Gigabit Ethernet PCI Express server adapters are designed for Servers and high-end appliances. The Silicom 25 Gigabit Ethernet PCI Express Server adapters offer simple integration into any PCI Express X8 to 25 Gigabit Networks. The performance is optimized so that system I/O is not the bottleneck in high-performance networking applications.

The Silicom 25 Gigabit Ethernet PCI Express server adapters are based on Broadcom BCM57304 Ethernet controller with fully integrated Gigabit Ethernet Media Access Control (MAC) and SFI Interface. In addition to managing MAC and PHY Ethernet layer functions, the controller manages PCI Express packet traffic across its transaction, link, and physical/logical layers. 

Using hardware acceleration, the controller offloads tasks from the host, such as TCP/UDP/IP checksum calculations and TCP segmentation.

Silicom’s 25 Gigabit Ethernet PCI-Express Server adapters are the ideal solution for implementing multiple network segments, mission-critical high-powered networking applications and environments within high performance servers.
