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).
