Intel® 10 Gigabit AF DA Dual Port Server Adapter

10 Gigabit Performance

for Top-of-Rack Connections

The Intel® 10 Gigabit AF DA Dual Port Server Adapter is the newest member of Intel’s robust family of 10 Gigabit products. Designed as a low-cost, low-power adapter, the Intel 10 Gigabit AF DA Dual Port Server Adapter provides direct attach copper twinaxial cable connections between servers and a top-of-rack switch. Two ports, coupled with a low-profile PCI Express* form factor, make this adapter ideal for slot-constrained environments. Using direct attach copper cables compliant with the SFP + MSA SFF-8431 specification, the Intel 10 Gigabit AD DA Dual Port Server Adapter is well-suited for customers who require low-cost “in-the-rack” connections of less than 10 meters between server and top-of-rack switch.

Energy-Efficient, Next-Generation 10 Gigabit Performance

10 Gigabit Ethernet is rapidly becoming the mainstay for backbones within enterprise and service provider networks. Intel’s 10GBASE Direct Attach adapter extends the 10 Gigabit adoption to the server rack. The escalating deployments of servers with multi-core processors and demanding applications such as high-performance computing (HPC), database clusters, virtualized servers and video on demand are driving the need for 10 Gigabit connections in the server rack. Based on the 82598EB 10 Gigabit Ethernet controller, Intel’s 10 Gigabit AF DA Server Adapter is designed to meet the throughput and latency requirements of bandwidth-hungry applications, while offering a very low-power envelope for energy efficiency.

Performance-Enhancing Features for Multi-Core Environments

As a member of the 10 Gigabit family of products, the 10GbE Direct Attach adapter supports all of the features and functionality in Intel’s other 82598EB-based adapters. When implemented within multi-core processor environments, the Intel 10 Gigabit AF DA Server Adapter offers advanced networking features for efficient

distribution of Ethernet workloads across CPU cores. Load balanc- ing of interrupts using MSI-X enables more efficient response times and application performance. CPU utilization can be lowered further through stateless offloads such as TCP segmentation offload, header replications/splitting, and Direct Cache Access (DCA).

Intel 10 Gigabit AF DA Server Adapters are optimized for virtualized environments, supporting multiple queues, alleviat- ing I/O bottlenecks between virtual machines. Virtual Machine Device queue1 (VMDq) technology offloads data sorting and data copying from the virtual machine monitor (VMM) software layer to the hardware, improving overall throughput and CPU utilization on virtualized servers. Additionally, Intel 10 Gigabit AF DA Server Adapters enable Intel® I/O Acceleration Technology2 (Intel® I/OAT) with support for Intel® QuickData for faster I/O processing on the new Quad-Core and Dual-Core Intel® Xeon® processor-based servers.

Conserve valuable PCI Express (PCIe*) server slots while adding 10 Gigabit Ethernet capability with Intel 10 Gigabit AF DA Server Adapters. The dedicated input/output (I/O) bandwidth of PCIe ensures priority performance on each port – without bus sharing – for 10 Gigabit Ethernet connectivity, as well as a low-profile design, which improves server throughput and rack density at the same time. In addition, eight-lane PCIe enables maximum bandwidth for fast and efficient data transfer. The low-power, efficient design allows for two 10 Gigabit Ethernet ports in a single low-profile PCIe adapter.
