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

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.
