Product Brief Intel 10 Gigabit AF DA Dual Port Server Adapter Network Connectivity 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 Intels 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 distribution of Ethernet workloads across CPU cores. Load balanc- Server Adapter is well-suited for customers who require low-cost ing of interrupts using MSI-X enables more efficient response times in-the-rack connections of less than 10 meters between server and application performance. CPU utilization can be lowered further and top-of-rack switch. through stateless offloads such as TCP segmentation offload, header replications/splitting, and Direct Cache Access (DCA). Energy-Efficient, Next-Generation Intel 10 Gigabit AF DA Server Adapters are optimized for 10 Gigabit Performance virtualized environments, supporting multiple queues, alleviat- 10 Gigabit Ethernet is rapidly becoming the mainstay for ing I/O bottlenecks between virtual machines. Virtual Machine backbones within enterprise and service provider networks. 1 Device queue (VMDq) technology offloads data sorting and Intels 10GBASE Direct Attach adapter extends the 10 Gigabit data copying from the virtual machine monitor (VMM) software adoption to the server rack. The escalating deployments of layer to the hardware, improving overall throughput and CPU servers with multi-core processors and demanding applications utilization on virtualized servers. Additionally, Intel 10 Gigabit AF such as high-performance computing (HPC), database clusters, 2 DA Server Adapters enable Intel I/O Acceleration Technology virtualized servers and video on demand are driving the need (Intel I/OAT) with support for Intel QuickData for faster I/O for 10 Gigabit connections in the server rack. Based on the processing on the new Quad-Core and Dual-Core Intel Xeon 82598EB 10 Gigabit Ethernet controller, Intels 10 Gigabit AF DA processor-based servers. Server Adapter is designed to meet the throughput and latency requirements of bandwidth-hungry applications, while offering a Conserve valuable PCI Express (PCIe*) server slots while adding very low-power envelope for energy efficiency. 10 Gigabit Ethernet capability with Intel 10 Gigabit AF DA Server Adapters. The dedicated input/output (I/O) bandwidth Performance-Enhancing Features of PCIe ensures priority performance on each port without for Multi-Core Environments bus sharing for 10 Gigabit Ethernet connectivity, as well as a As a member of the 10 Gigabit family of products, the 10GbE Direct low-profile design, which improves server throughput and rack Attach adapter supports all of the features and functionality in density at the same time. In addition, eight-lane PCIe enables Intels other 82598EB-based adapters. When implemented within maximum bandwidth for fast and efficient data transfer. The multi-core processor environments, the Intel 10 Gigabit AF DA low-power, efficient design allows for two 10 Gigabit Ethernet Server Adapter offers advanced networking features for efficient ports in a single low-profile PCIe adapter.Advances for Unified Storage The fast growth in storage capacity coupled with server virtual- reliable networked storage can be achieved via native iSCSI ization has brought the need for Storage Area Network (SAN) to support with Microsoft, Linux*, and VMware operating systems the forefront. To satisfy this growing demand, Intels 10 Gigabit as well as support for iSCSI remote boot. Advanced QoS features AF DA Server adapter supports iSCSI acceleration and provides such as priority groups and per priority pause are also imple- advanced features for unified storage connectivity. Fast and mented in the adapters.
