Overview
The new LREC***4HT builds on LR-LINKs history
of excellence.LR-LINK continues its market leadership with this
new generation of PCIe* GbE network adapters. Built with the
bridgeless Intel® Ethernet Controller I**0, these adapters
represent the next step in the Gigabit Ethernet (GbE) networking
evolution for the enterprise and data center by introducing new
levels of performance through industry-leading enhancements for
both virtualized and iSCSI Unified Networking environments. This
new family of adapters also includes new power management
technologies such as Energy Efficient Ethernet (EEE) and DMA
Coalescing (DMAC).
Flexible I/O
Virtualization
The LREC***4HT includes Intel® Virtualization
Technology for connectivity (Intel® VT-c) to deliver I/O
virtualization and Quality of Service (QoS) features designed
directly into the controller on the adapter. I/O virtualization
advances network connectivity models used in todays servers to
more efficient models by providing Flexible Port Partitioning
(FPP), multiple Rx/Tx queues, and on- controller QoS
functionality that can be used in both virtual and non-virtual
server deployments.
By taking advantage of the PCI-SIG SR-IOV
specification, the adapter enables Flexible Port Partitioning
(FPP). With FPP, virtual controllers can be used by the
Linux* host directly and/or assigned to virtual machines. With
this port partitioning, administrators can create up to eight
dedicated connections on a single Ethernet port for use in bare
metal and virtualized server deployments.
In a bare-metal Linux server, host processes
can be assigned to dedicated network resources to provide traffic
isolation and balanced bandwidth allocation.
In a virtualized environment, a VM can be
assigned to a virtual controller to reduce the CPU overhead seen
when using a software-based network bridge by offloading network
traffic management to the controller.
Scalable iSCSI
Performance
LREC***4HT with native iSCSI initiators built
into Microsoft* Windows*, Linux* and VMware* ESX platforms
provides a simple, dependable, cost-effective way to connect to
iSCSI SANs. These native initiators are broadly tested using
multiple generations of operating systems, storage systems, and
OS tools to help ensure reliability and ease of use.
Standardizing on LR-LINK® Ethernet Adapters for iSCSI enables
administrators to use a single initiator, TCP/IP stack, and a
common set of management tools and IT policies. In addition,
LR-LINK® Ethernet Server Adapters include a number of hardware
features designed to accelerate iSCSI traffic and enhance data
processing.
For example, TCP segmentation offload and
checksum offload capabilities help reduce processor usage,
increase throughput, and deliver exceptional iSCSI performance.
Finally, using native OS initiators, an LREC***4HT supports the
CRC**2 digest instruction set included with Intel® Xeon®
processor products, which improves transmission reliability and
delivers an enterprise-class iSCSI solution.
PowerManagementTechnologies
Today, companies everywhere are looking for
ways to decrease energy consumption across the enterprise to
reduce costs and environmental impact, while at the same time
solving increasingly important power density challenges. Thats
why LR-LINK has introduced new, advanced Power Management
Technologies (PMTs)with the LREC***4HT that enable enterprises to
configure power options on the adapter and more effectively
manage their power consumption.
Energy Efficient Ethernet
(EEE)
The LREC***4HT supports the IEEE**2.3az Energy
Efficient Ethernet (EEE) standard so that, during periods of low
network activity, EEE reduces the power consumption of an
Ethernet connection by negotiating with a compliant EEE switch
port to transition to a low power idle (LPI) state. This reduces
the controller power to approximately *0% of its normal operating
power, saving power on the network port and the switch port. As
soon as increased network traffic is detected, the controller and
the switch quickly come back to full power to handle the
increased network traffic. EEE is supported for both ***0BASE-T
and**0BASE-TX.
DMA Coalescing
Another power management technology that can
reduce power on the server platform is DMA Coalescing (DMAC).
Typically, when a packet arrives at a server, DMA calls are made
to transfer the packet within the server. These calls wake up the
processor, memory and other system components from a lower power
state in order to perform the tasks required to handle the
incoming packet.
Based on the configurable DMAC settings,
incoming packets are buffered momentarily before any DMA calls
are made. This enables the controller to intelligently identify
opportunities to batch multiple packets together so that when
components are wakened from lower power states they can
efficiently handle the batched packets at the same time. This
enables platform components to remain in lower power states
longer, which can dramatically reduce platform energy
consumption. DMAC synchronizes DMA calls across all controller
ports to ensure maximum power savings.
Software Tools and
Management
LR-LINK® Advanced Network Services (LR-LINK®
ANS) include new teaming technologies and techniques such as
Virtual Machine Load-Balancing (VMLB) for Hyper-V environments.
Today, LR-LINK ANS includes a variety of teaming configurations
for up to eight adapters, support for mixed vendors server
adapters teaming and includes support for **2.1q VLANs, making
LR-LINK ANS one of the most capable and comprehensive tools for
supporting server adapter teaming.
Additionally, Intel® PROSet for Windows*
Device Manager and PROset CL extends driver functionality to
provide additional reliability and Quality of Service features
and configuration.
