Intel’s new family of Intel® Ethernet X520 Server Adapters are the most flexible and scalable Ethernet adapters for today’s demanding data center environments.

The Intel® Ethernet X520 Server Adapter family 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.

Features and benefits
- Intel® 82599 10 Gigabit Ethernet Controller
Industry-leading, energy-efficient design for next-generation 10 Gigabit performance and multi-core processors;
- Low-profile
Enables higher bandwidth and throughput from standard and low-profile PCIe slots and servers;
- Load balancing on multiple CPUs
Increases performance on multi-processor systems by efficiently balancing network loads across
CPU cores when used with Receive-Side Scaling (RSS) from Microsoft or Scalable I/O on Linux*;
- iSCSI remote boot support
Provides centralized storage area network (SAN) management at a lower cost than other iSCSI solutions;
- Support for most network operating systems (NOS)
Enables widespread deployment;
- RoHS-compliant2
Complies with the European Union directive 2002/95/EC to reduce the use of hazardous materials;
- Intel® PROSet utility for Microsoft Windows* Device Manager
Provides point-and-click management of individual adapters, advanced adapter features, connection
teaming, and virtual local area network (VLAN) configuration;
- Time Sync (IEEE 1588, 802.1as)
Lets networked Ethernet equipment synchronize internal clocks according to a network master clock;
endpoint can then acquire an accurate estimate of the master time by compensating for link latency;
