Overview
The new DW-LCII350-4GC builds on DONGWE’s history of
excellence.DONGWE continues its market
leadership with this new generation of PCIe* GbE network
adapters.Built with the bridgeless Intel® Ethernet
Controller I350, 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 DW-LCII350-4GC 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 today’s
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
enable 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 baremetal 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
DW-LCII350-4GC 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 DONGWE®
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,DONGWE® 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
DW-LCII350-4GC supports the CRC-32 digest instruction set included
with Intel® Xeon® processor
products,which improves transmission reliability and delivers an
enterprise-class iSCSI solution.
Power Management Technologies
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. That’s why DONGWE has introduced new, advanced Power
Management Technologies
(PMTs)with the DW-LCII350-4GC that enable enterprises to configure
power options on the adapter and
more effectively manage their power consumption.
Energy Efficient Ethernet (EEE)
The DW-LCII350-4GC supports the IEEE802.3az 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 50% of its normal operating
power, saving power on the network port and
the switch port. As oon 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 1000BASE-T
and100BASE-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
DONGWE® Advanced Network Services (DONGWE® ANS) include new teaming
technologies and
techniques such as Virtual Machine Load-Balancing (VMLB) for
Hyper-V environments. Today,DONGWE
ANS includes a variety of teaming configurations for up to eight
adapters, support for mixed vendors server
adapters teaming and includes support for 802.1q VLANs, making
DONGWE 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.
