The Intel 82599 10 Gigabit Ethernet controller along with Intel® Xeon® processor 5500 series-based servers deliver unmatched performance scalability that signals a new paradigm in the data center — a paradigm of intelligent solutions that help manage growth while controlling costs; a paradigm of advanced virtualization features; and a paradigm of a simple, cost-effective, unified network.
The Intel 82599 10 Gigabit Ethernet controller includes Intel® Virtualization Technology for Connectivity (Intel VT-c) to delivers better performance in virtualized server environments. Intel VT-c includes hardware optimizations that help reduce I/O bottlenecks and improve the overall server performance. These technologies are Virtual Machine Device Queues (VMDq) and Virtual Machine Direct Connect (VMDc). VMDq improves data processing by offloading the sorting and queuing functionality to the I/O controller from the VMM. VMDc provides direct connectivity to the VMs to deliver near-native performance and VM scalability. VMDc also provides flexibility with mobility by enabling VM migration between physical servers. VMDc is based on the industry-standard PCI-SIG SR-IOV (Single Root I/O Virtualization).
