Product Details

PCI Express Fiber 40 Gigabit Ethernet Server Adapter (PN: S9901BF-QSFP)
(Intel XL710AM1 Based)

The 40 Gigabit Ethernet PCI Express server adapter is designed for Servers and high-end appliances. S9901BF-QSFP offer simple integration into any PCI Express X8 to 40Gigabit Networks. The performance is optimized so that system I/O is not the bottleneck in high-performance networking applications.

S9901BF-QSFP is based on Intel XL710AM1 Ethernet controller with two fully integrated Gigabit Ethernet Media Access Control (MAC) and XLPPI 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.

The card is the ideal solution for implementing multiple network segments, mission-critical high-powered networking applications and environments within high performance servers.
