Energy-Efficient, Next-Generation
10 Gigabit Performance
10 Gigabit Ethernet has moved past the early adoption stage and
is rapidly becoming the 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 a 10 Gigabit
connection. The Intel® 82598 10 Gigabit Ethernet Controller is
a next-generation, PCI Express* 2.0 (2.5 Gbps) controller with
balanced features and energy-efficient design that meets the
throughput and latency requirement of bandwidth-hungry
applications. The 82598 controller is designed for multi-core
processors and implements advanced features for efficient
routing of packets using multiple queues as well as include load
balancing of interrupts using MSI-X. The controller also supports
stateless offloads such as TCP segmentation offload, header
replications/splitting, and Direct Cache Access (DCA) to lower
CPU utilization. In addition, the 82598 controller offers advanced
features for Virtualization and Storage over Ethernet all within a
very low power envelop of 4.8W (dual port).
High-Performance Design Features
The Intel 82598 10 Gigabit Ethernet Controller is a single,
compact component with two fully integrated 10 Gigabit Ether-
net Media Access Control (MAC) and XAUI ports. The controller
supports CX4 (802.3ak*) and KX4/KX (802.3ap*) interfaces and
each port contains a Serializer-Deserializer (SerDes) for backward
compatibility with gigabit backplanes. 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 includes advanced
interrupt-handling features and uses efficient ring-buffer
descriptor data structures, with up to 64 packet descriptors
cached on chip. A large on-chip packet buffer maintains superior
performance. The 82598 controller enables network manageabil-
ity 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 Distributed
Management Task Force (DMTF)-defined NC-SI.

Hardware-assisted Virtualization
As IT focuses on reducing costs by deploying virtualization
and consolidating servers, this new environment also creates
unique challenges for the I/O infrastructure. Recognizing these
challenges, Intel has designed smart acceleration capabilities into
Ethernet Controllers that optimizes networking performance on
virtual servers. The Intel 82598 10 Gigabit Ethernet Controller
adds Virtual Machine Device queue (VMDq) technology that
offloads data sorting and data copying from the virtual machine
monitor (VMM) software layer to the hardware. This improves
overall throughput and CPU utilization on virtualized servers.
VMDq technology also ensures transmit fairness and prevents
head-of-line blocking to deliver enhanced latency performance.
Advanced Features for Storage over Ethernet
The fast growth in storage capacity coupled with server virtu-
alization has brought the need for Storage Area Network (SAN)
in the forefront. To satisfy this growing demand Intel 82598 10
Gigabit Ethernet Controller includes support for iSCSI accelera-
tion and advanced features for unified storage connectivity.
The controller enables fast and reliable networked storage with
native iSCSI support with Microsoft, Linux,* and VMware operat-
ing systems as well as support for iSCSI remote boot. Advanced
QoS features such as priority groups and per priority pause are
also implemented in the controller. These hardware features
facilitate Host I/O consolidation and enable migration for Fibre
Channel over Ethernet as an alternative to expensive Fibre
Channel Host Bus adapters (HBAs).
