INTEL 10 Gigabit X520 SR2 Dual port Server Adapter PCI-E

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
