The D-Link DXE-820T Dual Port 10GBASE-T RJ-45 PCI Express Adapter is a high performance adapter designed for the high-speed PCI Express bus architecture. The Dual Port 10GBASE-T RJ-45 PCI Express Adapter offers increased bandwidth, reliability, and more functionality than standard PCI network cards. It is specifically designed to allow throughput at rates up to 40 Gbps, thus eliminating the bottleneck that exists with current 32 and 64-bit PCI bus architectures.

Advanced Features and Security

The adapter features onboard screening of 802.1Q VLAN tagged Ethernet frames, allowing you to assign multiple subnets to each server and isolate devices within each VLAN from the rest of the network for better traffic control and security. With support for advanced features such as 802.3x flow control, jumbo frames, and SNMP for network management, the DXE-820T can easily interoperate with your current networking equipment.

Performance and Reliability

The DXE-820T increases network throughout by utilizing PCI Express bus architecture. With Smart Load BalancingTM the DXE-820T configures multiple adapters to work as a team, sharing traffic and ensuring data reliability. This both creates a faster network and provides fault tolerance resulting in a stable and efficient network.

Checksum Offloading

The DXE-820T features TCP, UDP, and IP checksum offloading functionality, which transfers the checksum processing tasks from the computer’s CPU to the network card. The DXE-820T’s ability to handle the checksum processing means that the CPU’s processing power can be used for other tasks while still achieving 20 Gbps network speeds.
