PE425G2I81 25G Ethernet PCIe Server Adapter Intel® E810 Based
Dual Port Fiber 25 Gigabit Ethernet PCI Express Server Adapter Intel® E810 Based
Silicom’s PE425G2i81 25 Gigabit Ethernet PCI Express server adapter is designed for Servers and high-end appliances. The PE425G2i81 25 Gigabit Ethernet PCI Express Server adapters offer simple integration into PCI Express x16 to 25Gigabit Networks. The performance is optimized so that system I/O is not the bottleneck in high-performance networking applications.
The PE425G2i81 25 Gigabit Ethernet PCI Express server adapter is based on Intel E810 XXVAM2 Ethernet controller with fully integrated 25 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.
