The Intel® X520 Dual Port Adapter (N2XX-AIPCI01) is a high-performance network interface card tailored for data-intensive environments. It supports 128 Tx and Rx queues per port, advanced offloading for IP/TCP/UDP protocols, and segmentation features that significantly lower processor usage. Additional features like IPsec and MacSec offloads, Receive and Transmit Side Scaling, and compatibility with multiple OS environments make it a robust choice for enterprise virtualization, storage, and high-throughput networking tasks.
This dual-port X520 adapter is ideal for enterprises leveraging virtualization or converged network infrastructures. Its capability to offload CPU-intensive tasks like encryption and segmentation enables higher server efficiency and lower latency. The dual 10Gb SFP+ ports provide redundancy and scalability, ensuring high availability and performance in cloud environments, software-defined data centers, and SANs. This makes it especially useful in setups where uptime, throughput, and CPU optimization are mission-critical.
