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 con-

nectivity 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).

Unified Networking

Intel 82599 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 for guaranteed packet delivery, 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, Linux,* and VMware

operating systems and provides a robust iSCSI remote boot

implementation. Further, the Intel 82599 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 eliminat-

ing a data copy through Direct Data placement implementation.

Integrated Solution for LAN

on Motherboard (LOM)

The Intel 82599 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 industry-leading power consumption, a small footprint, and

integrated PHYs, the controller is ideally suited for Server Blades,

LAN on motherboard (LOM), NIC, and Mezzanine card implemen-

tations. The advanced features of the Intel 82599 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.
