D7N7W Dell Intel X520-DA2 SFP+ Ethernet Converged Network Adapter | Brand New

The D7N7W Dell Intel X520-DA2 SFP+ Ethernet Converged Network Adapter is a high-performance network interface card (NIC) designed for use in servers that require high-speed connectivity to other devices on a network. This card is designed to provide a reliable and efficient way to connect servers to storage arrays, switches, and other servers. In this article, we will explore the features of this card in detail.

Features

The D7N7W Dell Intel X520-DA2 SFP+ Ethernet Converged Network Adapter features two SFP+ ports, each capable of providing a maximum transfer rate of 10 Gbps. This means that the card can provide a total maximum throughput of 20 Gbps when both ports are used simultaneously. The card is designed to be used with PCIe x8 slots, which provide sufficient bandwidth to accommodate the high-speed connectivity provided by the card.

The card is also designed to be compatible with a range of network protocols, including Ethernet, Fibre Channel over Ethernet (FCoE), and iSCSI. This makes it a versatile card that can be used in a variety of different network environments.

Compatibility

The D7N7W Dell Intel X520-DA2 SFP+ Ethernet Converged Network Adapter is designed to be compatible with a wide range of Dell servers, including the Dell PowerEdge R620, R720, R720XD, R820, T620, and M620. The card is also designed to work with a range of operating systems, including Microsoft Windows, Linux, and VMware ESXi.

Advanced features

In addition to its high-speed connectivity and broad compatibility, the D7N7W Dell Intel X520-DA2 SFP+ Ethernet Converged Network Adapter also includes a range of advanced features designed to enhance performance and reliability. These features include:

• Direct Memory Access (DMA): The card features DMA technology, which allows data to be transferred directly between the network adapter and memory, bypassing the CPU and reducing latency.
• Receive Side Scaling (RSS): This feature distributes incoming network traffic across multiple CPUs, improving performance and reducing CPU utilization.
• Intelligent Offloads: The card includes a range of offload engines that can offload processing tasks from the CPU, improving performance and reducing CPU utilization. These engines include TCP/IP offload, iSCSI offload, and FCoE offload.
• Virtualization support: The card includes support for VMware NetQueue and Microsoft VMQ, which allow virtual machines to access the network adapter directly, improving performance and reducing CPU overhead.

In summary, the D7N7W Dell Intel X520-DA2 SFP+ Ethernet Converged Network Adapter is a high-performance network adapter designed for use with servers that require high-speed connectivity to other devices on a network. The card features two SFP+ ports, each capable of providing a maximum transfer rate of 10 Gbps, and is compatible with a range of network protocols. The card is also designed to be compatible with a wide range of Dell servers and operating systems and includes a range of advanced features designed to enhance performance and reliability.
