Intel® 10 Gigabit AT 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
The Intel® 10 Gigabit AT Ethernet Server Adapter showcases Intel’s first-generation standards-based 10BASE-T adapter in a low- profile PCI Express* form factor. It provides bandwidth-intensive 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 with the standardized connectivity of the Intel 10 Gigabit AT Server Adapter. Intel’s adapter also provides 1000BASE-T support for gigabit connections to legacy switches.
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. Based on the Intel® 82598EB 10 Gigabit Ethernet Controller, this next-generation Intel 10 Gigabit AT Server Adapter is designed to meet the throughput requirements of bandwidth-hungry applications.
Performance-Enhancing Features for Multi-Core Environments
When implemented within multi-core processor environments, the Intel 10 Gigabit AT Server Adapter offers advanced networking features for efficient distribution of Ethernet workloads across CPU cores. Load balancing 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).
The Intel 10 Gigabit AT 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 AT Server Adapter enables Intel® I/O Acceleration Technology1 (Intel® I/OAT) with support for Intel® QuickData Technology for faster I/O processing on the new Quad-Core and Dual- Core Intel® Xeon® processor-based servers.
