Is Gigabit Ethernet Too Slow? You Might Need More Fiber

Intel® Ethernet X520-SR2: Dual 10 Gigabit LC Fiber NIC w/ SFP+ Support
The Intel® Ethernet Controller X520-SR2 is Intel's latest industry-leading innovation to reduce the cost of 10Gb Ethernet and bring it to the broad server market.

Intel's new family of Intel® Ethernet Converged Network Adapter X520 are the most flexible and scalable Ethernet adapters for today's demanding data center and cloud environments.

The Intel® Ethernet Converged Network Adapter X520 family addresses the demanding needs of the next-generation data center by providing unmatched features for virtualization, flexibility for LAN and storage area network (SAN) networking, and proven, reliable performance.

Best Choice for Virtualization

Intel's X520 Series Ethernet Converged Network Adapters address Network Bottlenecks in Virtualized environments. These Adapters enable network intensive application to achieve the performance expected in a virtualized environment.

Unified Networking and Storage

Intel® Ethernet X520 Adapters lowers your data center TCO (total cost of ownership) by providing the ability tot route LAN and SAN traffic over a single Fiber, even when it has two Fiber Ports.

Native iSCSI Support

Intel® X520 Series Ethernet Converged Network Adapters provide complete support for proven native OS and VMM iSCSI initiators as well as iSCSI boot. Historically, CRC32C Computation has degraded system performance, but now with the CRC instruction srt included in the latest XEON® CPUs, CRC validation is possible with minimal impact to network throughput while delivering superior data integrity.

The Intel Ethernet Family of X520 Adapters do it all, including 10 Gigabit LAN and iSCSI; truly delivering on the promise of unified networking!
