Intel Ethernet Server Adapter X520-DA1 - Network Adapter - PCIe 2.0 X8 - 10 GigE

• 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 (FCoE)
  FCoE encapsulates Fiber Channel frames over standard Ethernet networks, enabling Fiber Channel to take advantage of 10GbE networks while preserving its native protocol. The X520 server adapters offer FCoE hardware acceleration to provide performance comparable to FC HBAs. The server adapters support data center bridging, also known as Converged Enhanced Ethernet (CEE), which allows customers to configure traffic classes and priorities to deliver a lossless Ethernet fabric. An Intel Ethernet X520 server adapter reduces TCO by eliminating redundant fabrics and saves the cost of expensive FC HBAs and FC switch ports.
• Support for iSCSI
  The server 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 set included in the Intel Xeon processors, CRC validation is possible with minimal impact to network throughput while delivering superior data integrity. The Intel Ethernet family of X520 server adapters does it all: 10 Gigabit LAN, FCoE, and iSCSI; truly delivering on the promise of unified networking.
• Designed for multi-core processors
  Support for technologies such as Intel QuickData, multiple MSI-X vectors, and Low Latency Interrupts allow the X520 server adapters to provide high-performance, 10 Gigabit connectivity in multi-core server blades. These technologies distribute network processing across multiple CPU cores, improving overall performance. For today's demanding virtualized data center environments, the family of X520 server adapters delivers ultimate flexibility and scalability.

Intel's family of Intel Ethernet X520 server adapter is the most flexible and scalable Ethernet adapter for today's demanding data center environments. Data center networks are being pushed to their limits. The escalating deployments of servers with multi-core processors and demanding applications such as High Performance Computing (HPC), database clusters, and video-on-demand are driving the need for 10 Gigabit connections. Customers require flexible and scalable I/O solutions to meet the rigorous requirements of running mission-critical applications in virtualized and unified storage environments.
Powered by Intel's third-generation 10GbE network controller, the Intel Ethernet 82599 10 Gigabit Ethernet controller, the 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.
