Intel® 10 Gigabit AT2 Server Adapter Network Connectivity

Intel® 10 Gigabit AT2 Server Adapter
10 Gigabit BASE-T Ethernet Server Adapters Designed for Multi-Core Processors and Optimized for Virtualization
10 Gigabit Performance at the Low Cost of Copper
This 10 Gigabit AT2 Ethernet Server Adapter showcases Intel’s second-generation standards-based 10GBASE-T adapter in alow-profile PCI Express* form factor. It provides bandwidthintensive applications highly affordable 10 Gigabit Ethernet (GbE) network performance with cost-effective RJ-45 connections for distances up to 100 meters. High-speed server connectivity — once reserved for costly, proprietary technologies such as High Performance Computing (HPC) clusters and grid-based computing — can now be achieved withthe standardized connectivity of the Intel® 10 Gigabit AT2 Server Adapter. Intel’s adapter also provides 1000BASE-T support for gigabit connections to legacy switches. 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).Next-Generation 10 Gigabit Performance
10 Gigabit Ethernet has moved past the early adoption stage and is rapidly becoming mainstay for backbones within enterprise and service provider networks. The escalating deployments of servers with multi-core processors and demanding applications such as HPC, database clusters, and video on demand are driving the need for 10 Gigabit connections. Basedon the Intel® 82598EB 10 Gigabit Ethernet Controller, this next-generation Intel 10 Gigabit AT2 Server Adapter is designed to meet the throughput requirements of bandwidth-hungry applications.

The Intel 10 Gigabit AT2 Server Adapter is optimized for virtualized environments, supporting multiple queues, alleviating I/O bottlenecks between virtual machines. Virtual Machine Device Queue (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, the Intel 10 Gigabit AT2 Server Adapter enables Intel® QuickData Technology1 for faster I/O processing on Quad-Core and Dual-Core Intel® Xeon® processor-based servers. Conserve valuable PCIExpress (PCIe*) server slots while adding 10 Gigabit Ethernet capability with the Intel 10 Gigabit AT2 Server Adapter. 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 PCIeenables maximum bandwidth for fast and efficient data transfer.

Performance-Enhancing Features for Multi-Core Environments
When implemented within multi-core processor environments, the Intel 10 Gigabit AT2 Server Adapter offers advanced networking features, Intel® I/O Acceleration Technology (Intel® I/OAT), for efficient distribution of Ethernet workloads across CPU cores. Load balancing ofinterrupts using

Advances for Storage Over Ethernet
The fast growth in storage capacity coupled with server virtualization has brought the need for Storage Area Network (SAN) to the forefront. To satisfy this growing demand, Intel 10 Gigabit AT2 Server Adapters support iSCSI acceleration through Intel I/OAT and provide advanced features for unified networking. Fast and reliable networked storagecan be achieved via native iSCSI support with Microsoft, Linux,* and VMware operating systems as well as support for iSCSI remote boot.
