Product Details

Intel® 82599ES 10 Gigabit Ethernet Controller transforms the data center through a reliable and unified 10GbE network.

The Intel 82599ES 10 Gigabit Ethernet controller along with Intel® Xeon® processor 5500 series-based servers delivers 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 deliver 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).

Intel 82599ES 10 Gigabit Ethernet controller reduces cost and complexity of the data center by combining LAN and SAN traffic onto a single Ethernet fabric. Customers can use iSCSI, NAS or FCoE to carry storage traffic over Ethernet. In order to meet SAN requirements, the controller implements capabilities such as enhanced transmission selecting and priority flow control. The controller accelerates iSCSI traffic by implementing key stateless offloads such as TCP segmentation offload (TSO) and Receive Side Coalescing (RSC). It also supports the trusted iSCSI initiators from Microsoft and Linux operating systems and provides a robust iSCSI remote boot implementation. Further, the Intel 82599ES 10 Gigabit Ethernet controller delivers a high performing FCoE solution that offloads the main data paths for I/O read and write commands. It also greatly reduces CPU processing on FCoE receive traffic by eliminating a data copy through Direct Data placement implementation.

The Intel 82599ES 10 Gigabit Ethernet controller it is a single-chip, dual-port 10GbE implementation in a 25x25 mm package. It reduces BOM cost and design complexity by integrating serial 10GbE PHYs and provides both SFI and KR interfaces. The device is designed for high performance and lower memory latency. Wide internal data paths eliminate performance bottlenecks by efficiently handling large address and data words. The controller also includes advanced interrupt-handling features and uses efficient ring-buffer descriptor data structures, with up to 64 packet descriptors. A large on-chip packet buffer maintains superior performance. The controller enables network manageability implementations required by IT personnel for remote control and alerting. The communication to the Board Management Controller (BMC) is available either through an on-board System Management BUS (SMBus) port or though the DMTF-defined NC-SI.

With better power consumption, a small footprint, and integrated PHYs, the controller is ideally suited for Server Blades, LAN on motherboard (LOM), NIC, and Mezzanine card implementations. The advanced features of the Intel 82599ES 10 Gigabit Ethernet controller along with the Intel Xeon processor 5500 series enable customers to scale volume servers to fully utilize and scale to 10GbE capacity.
