Intel Ethernet Converged Network Adapter X520-DA2 - Network Adapter - PCIe 2.0 X8 Low Profile - 10Gb Ethernet X 2 - E10G42BTDABLK

• 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 balance 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.
• Intel Direct Cache Access (DCA)
  Enables the adapter to pre-fetch the data from memory, avoiding cache misses and improving application response time.
• MSI-X support
  Minimizes the overhead of interrupts. Load-balancing of interrupt handling between multiple cores/CPUs.
• Low latency interrupts
  Based on the sensitivity of the incoming data, the adapter can bypass the automatic moderation of time intervals between the interrupts.
• Header splits and replication in receive
  Helps the driver focus on the relevant part of the packet without the need to parse it.
• IPsec offload
  Offloads IPsec capability onto the adapter instead of the software to significantly improve I/O throughput and CPU usage.
• Virtual Machine Load Balancing (VLMB)
  Virtual Machines Load Balancing (VMLB) provides traffic load balancing across virtual switch, port, cable, or adapter failure.
• Watchdog timer
  Gives an indication to the manageability firmware or external devices that the chip or the driver is not functioning.

Intel's family of adapter, the Intel' Ethernet Converged Network Adapter X520 with SFP+ connectivity, is the 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 Gbps 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.
