Intel X520-DA2 PCI-Express Network Adapter - 2 x 10GB - Intel X520-DA2

Intel® Ethernet X520-DA2 Dual-Port 10 Gigabit SFP+ Ethernet Server Adapter Provides Ultimate Flexibility and Scalability in Virtual and Unified Storage Environments

Intel’s Ethernet X520-DA2 Server Adapter with SFP+ connectivity is the most flexible and scalable Ethernet adapter for today’s demanding data center environments. Data center networks are being pushed to their limits. The escalating deployments of servers with multi-core processors and demanding applications such as High Performance Computing (HPC), database clusters, and video-on-demand are driving the need for 10 Gigabit connections. Customers require flexible and scalable I/O solutions to meet the rigorous requirements of running mission-critical applications in virtualized and unified storage environments. Powered by Intel’s third-generation 10 GbE network controller, the Intel® X520-DA2 PCI-Express Network Adapter addresses the demanding needs of the next-generation data center by providing unmatched features for virtualization, flexibility for LAN and SAN networking, and proven reliable performance. 

Best Choice for Virtualization 

The explosive growth in virtualization is leading to an increasing demand for network performance. With more Virtual Machines (VMs) running on each multi-core server, networking traffic is dramatically increased with each VM competing for available I/O bandwidth. Intel’s Ethernet X520-DA2 Server Adapter addresses networking bottlenecks in virtualized environments. This adapter enables network-intensive applications to achieve the performance expected in a virtualized environment.
