The NetXtreme II 5709 Quad Port Gigabit Ethernet Mezzanine I/O Card from Dell is an ideal solution for your Dell blade servers implementing virtualization. Its valuable ports provide segmentation in environments where security is a significant factor. In addition, the 5709 card features TOE (TCP/IP Offload Engine) which performs accelerated networking on standard Ethernet and reduces server CPU utilization with improved application performance. This card is equipped with Receive Side Scaling (RSS) which enables packets receive processing to scale with the number of available processors. Moreover, its Smart Load Balancing feature helps increase throughput and fault tolerance, when network interface cards are configured together as a team to share traffic and eliminate bottlenecks. This product has been tested and validated on Dell systems. It is supported by Dell Technical Support when used with a Dell system.
