The best-selling Intel Ethernet Server Adapter X520-DA1 and X520-DA2 are known for their high performance, low latency, reliability, and flexibility. The addition of the Open Compute Project (OCP) server adapter to the family delivers the Intel Ethernet Server Adapter X520-DA1/X520-DA2 capabilities in an OCP form factor. The Intel Ethernet Server Adapter X520-DA1/X520-DA2 for OCP delivers a proven, reliable solution for deployments of Ethernet for high-bandwidth, low-cost, 10-Gb E network connections. Increased I/O performance with Intel Data Direct I/O Technology and support for intelligent offloads make this adapter a perfect match for scaling performance on Intel Xeon processor E5/E7-based servers. Powered by the Intel 82599 10 Gigabit Ethernet Controller, the Intel Ethernet Server Adapter X520-DA1/X520-DA2 for OCP addresses the demanding needs of the next-generation data center by providing unmatched features for virtualization and proven, reliable performance. The Intel 82599 10 Gigabit Ethernet Controller is the industry standard for 10 Gb E, making it the most popular 10 Gb E controller on the market today. 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 family of Intel Ethernet X520 Server Adapters addresses networking bottlenecks in virtualized environments. These adapters enable network-intensive applications to achieve the performance expected in a virtualized environment. Support for Fiber Channel over Ethernet (FCo E) FCo E encapsulates Fiber Channel frames over standard Ethernet networks, enabling Fiber Channel to take advantage of 10Gb E networks while preserving its native protocol. The X520 server adapters offer FCo E hardware acceleration to provide performance comparable to FC HBAs. The server adapters support Data
