Adaptec ANA-7711F KIT - fiber optic networking card

Adaptec TOE NAC 7711F (fiber optic) network accelerator card. 1 Gbit/sec half duplex; 2 Gbit/sec full duplex The Adaptec TOE NAC 7711C & 7711F network accelerator cards are the industry's first fully offloaded TCP/IP Offload Engines (TOE) for gigabit Ethernet environments. Ideal for TCP-based network intensive applications, the Adaptec 7711 expands the network interface from a basic network connection to a network accelerator. By offloading the entire TCP/IP stack to the on-board ASIC, Adaptec 7711 cards remove TCP/IP processing from the host processor and allow the host to focus more CPU resources on demanding applications. This drives substantially lower response time and increased throughput resulting in enhanced application performance with very low CPU utilization.

Demands on corporate LANs are increasing dramatically. Files are becoming larger and more complex; and applications are becoming so compute-intensive that farms of server clusters and NAS data storage are required to address computational needs. The data rates driven by these kinds of applications frequently reach Gigabit Ethernet speeds. Because processing 1Gbit of TCP/IP traffic typically requires up to 1 GHz of CPU power, TCP/IP processing saturates the servers, leaving little remaining CPU power to process target applications. As a result, these overburdened CPUs slow large file transfers, clustered high-performance computing, LAN based backup, NAS solutions, and other networked applications. NACs relieve the burden of TCP/IP processing and accelerate these network-intensive applications.
