The new Intel Ethernet family of X520 server adapters do it all:
10 Gigabit LAN, FCoE, and iSCSI storage traffic; truly delivering on the promise of unified networking.

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 new family of Intel Ethernet X520 Server Adapters addresses networking bottlenecks in virtualized environments. These new adapters enable network–intensive applications to achieve the performance expected in a virtualized environment.

Reliable Performance
The family of X520 server adapters include a number of advanced features (Security Optimizations, PCIe v2.0 (5 GT/s), Designed For Multi-core Processors) that allow it to provide industry–leading performance and reliability. For today's demanding virtualized data centre environments, the new family of X520 server adapters deliver ultimate flexibility and scalability.

Unified Networking and Storage
The family of Intel Ethernet X520 server adapters lowers your data centre total cost of ownership (TCO) by providing the ability to route LAN and SAN traffic over a single fabric, support for Fiber Channel over Ethernet (FCoE) and iSCSI.

Powered by Intel's third-generation 10 GbE network controller, the Intel® Ethernet 82599 10 Gigabit Ethernet Controller, the X520 server adapter family addresses the demanding needs of the next–generation data centre by providing unmatched features for virtualization, flexibility for LAN and SAN networking, and proven, reliable performance.
