Intel Ethernet Converged Network Adapter XL710-QDA2 / Network adapter / PCIe 3.0 x8 low profile / 40 Gigabit QSFP+ x 2 | XL710QDA2BLK

Description

Intel continues its legacy of Ethernet leadership by introducing a 10/40 gigabit family of adapters powered by, the Intel Ethernet XL710 Controller, codenamed Fortville. The XL710 adapter family addresses the demanding needs of the next-generation agile data center by providing unmatched features for both server and network virtualization, flexibility for LAN and SAN networks, and proven, reliable performance.

Special Features

• PCI Express (PCIe) 3.0, x8
• Exceptional low power adapters
• Network Virtualization offloads including Geneve, VXLAN, and NVGRE
• Intel Ethernet Flow Director for hardware-based application traffic steering
• Intel Data Plane Developer Kit (DPDK) optimized for efficient packet processing
• Excellent small packet performance for network appliances and Network Function Virtualization (NFV)
• Intelligent offloads to enable high performance with Intel Xeon processor-based servers
• I/O virtualization innovations for maximum performance in a virtualized server

Product features

• A complete, unified networking solution
  Converging data and storage onto one fabric eliminates the need for multiple adapters, cables, and switches. Furthermore both 10 and 40 gigabit Ethernet provides the bandwidth to converge these multiple fabrics onto a single wire. A key capability that makes all this possible is traffic class separation provided by Data Center Bridging (DCB) - providing a one-wire solution with virtual pipes for the different classes of traffic.
• One adapter, one price
  With the Intel adapters, iSCSI and FCoE support are included in the price of an adapter. There is no need to purchase multiple adapters or additional licensing for an XL710 adapter. It's simple and easy. Everything you need to unify your networking is included in a single SKU.
• Lowest power consumption
  The new generation of XL710 adapters are power misers. They deliver double the throughput with only half the power of the previous generation.
• Energy efficient Ethernet (EEE)
  Reduces power consumption during periods of low data activity. Energy is used to maintain the physical layer transmitters in a "ready state" to transmit data on the wire. During periods of low data traffic, EEE sends a low-power-idle signal to put the transmitters into a "low power state" saving power and cost. When data needs to be sent, EEE sends a normal idle signal to wake up the transmit system before data is due to be sent so there is no degradation of performance.
• Server virtualization
  With Intel Virtualization Technology (Intel VT), the XL710 family of adapters deliver outstanding I/O performance in virtualized server environments. They reduce I/O bottlenecks by providing intelligent offloads for networking traffic per virtual machine (VM), enabling near-native performance and VM scalability.
• Network virtualization
  Network virtualization is the next big trend in creating an agile data center. The family of XL710 adapters are ready to help you take that next step.
• VXLAN, NVGRE, Geneve Offloads
  These stateless offloads preserve application performance for overlay networks. With these offloads it is possible to distribute network traffic across CPU cores. At the same time XL710 offloads LSO, GSO, and checksum from the host software reducing CPU overhead.
• Intel Ethernet flow director
  Flow Director is an advanced traffic steering capability built into the XL710 controller. It consists of a large number of flow affinity filters that direct received packets by their flows to queues for classification, load balancing, and matching between flows and CPU cores. It eliminates context switching required within the CPU. As a result, Flow Director significantly increases the number of transactions per second and reduces latency for cloud applications like Memcached.
• Intelligent offloads
  The Intel Xeon processor family has demonstrated increased computing performance and increased integration of key server subsystems generation after generation. To offload is to leverage the ever-escalating computing power of the Intel Xeon processor where appropriate and implement complementary accelerations in the network controller - this is what Intel refers to as "intelligent offloads." By employing a balanced hybrid of compute and offload, intelligent offloads are able to achieve the optimized point of performance and efficiency.
