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 High Performance Computing (HPC), database clusters, and video-on-demand are driving the need for 10 Gigabit connections. Based on the Intel® 82598EB 10 Gigabit Ethernet Controller, the next-generation Intel® 10 Gigabit XF SR Server Adapter are designed to meet the throughput and latency requirements of bandwidth-hungry applications, while offering a very low power envelope for energy efficiency. Ideal for slot-constrained environments, the Intel® 10 Gigabit XF SR Dual Port Adapter provides a simplified alternative to multiple 1 Gbps server adapters.
Performance-Enhancing Features for Multi-Core Environments
When implemented within multi-core processor environments, Intel® 10 Gigabit XF SR Server Adapters offer 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).
Intel® 10 Gigabit XF SR Server Adapters are 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, Intel® 10 Gigabit XF SR Server Adapters enable Intel® I/O Acceleration Technology (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.
