Marketing description

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.

Produktegenskaper

• 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.
