Description:
DONGWE DW-LCI82599-2SFP+10G Server Adapters with SFP+ connectivity are the most flexible and
scalable Ethernet adapt- ers for today’s demanding data center environments. Data center networks are
being pushed to their limits. 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 10 Gigabit connections. Customers require flexible and scalable
I/O solutions to meet the rigorous requirements of running mission-critical
applications in virtualized and unified storage environments.
Best Choice for Virtualization
The explosive growth in virtualization is leading to an increasing demand for network performance. With more
Virtual Machines (VMs) running on each multi-core server, networking traffic is dramatically increased with
each VM competing for available I/O bandwidth. Intel’s family of DONGWE DW-LCI82599-2SFP+ 10G
Server Adapters addresses networking bottlenecks in virtualized environments. These adapters enable
network-intensive applications to achieve the performance expected in a virtualized environment.
The DONGWE 10G DW-LCI82599-2SFP+server adapter provides the best networking performance
available in the industry, whether the physical port is configured in an emulation mode using the virtual switch
in the Virtual Machine Monitor (VMM), or is directly assigned to a virtual machine. In the emulation mode,
Intel’s I/O technology, Virtual Machine Device queues1 (VMDq) optimizes network performance by
offloading data sorting and copying from the software Virtual Switch in the VMM to the Intel Ethernet 82599
10 Gigabit Controller. This configuration is best suited for a large number of VMs running standard applications that have limited bandwidth and latency requirements.
For mission-critical applications, where dedicated I/O is required for maximum network performance, users
can assign a dedicated virtual adapter port to a VM. Using the PCI-SIG SR-IOV capability on an DONGWE
DW-LCI82599-2SFP+ 10G server adapter provides direct VM connectivity and data protection across VMs.
SR-IOV technology allows the data to bypass the software virtual switch and provides near-native
performance. It assigns either physical or virtual I/O ports to individual VMs directly. This technology is best
suited for applications that demand the highest I/O throughput and lowest latency performance such as
database, storage, financial and other applications.
PCI-SIG SR-IOV is a mechanism for devices to advertise their ability to be directly assigned to multiple virtual
machines. SR-IOV allows for the partitioning of a PCI function into many virtual interfaces for the purpose of
sharing the resources of a PCI Express* (PCIe) device in a virtual environment. These virtual interfaces are
called Virtual Functions. Each virtual function
can support a unique and separate data path for I/O-related functions within the PCI Express hierarchy. Use
of SR-IOV with a networking device, for example, allows the bandwidth of a single port (function) to be
partitioned into smaller slices that may be allocated to specific VMs, or guests, via a standard interface.
The DONGWE DW-LCI82599-2SFP+ 10G server adapter delivers the same functionality and throughput as
ten dual-port, one gigabit adapters, saving cost, power, and complexity.
Unified Networking and Storage
The family of DONGWE DW-LCI82599-2SFP+ 10G server adapters lowers your data center total cost of
ownership (TCO) by providing the ability to route LAN and SAN traffic over a single fabric.
Support for Fiber Channel over Ethernet (FCoE)
FCoE encapsulates Fiber Channel frames over standard Ethernet networks, enabling Fiber Channel to take
advantage of 10 GbE networks while preserving its native protocol. The DONGWE
DW-LCI82599-2SFP+10G server adapter offer FCoE hardware acceleration to provide performance
comparable to FC HBAs. The server adapters support Data Center Bridging, also known as Converged
Enhanced Ethernet (CEE), which allows customers to configure traffic classes and priorities to deliver a
lossless Ethernet fabric. An Intel Ethernet X520 server adapter reduces TCO by eliminating redundant fabrics
and saves the cost of expensive FC HBAs and FC switch ports.
Support for iSCSI
The server adapters provide complete support for proven native OS and VMM iSCSI initiators as well as
iSCSI boot. Historically, CRC32C computation has degraded system performance, but now with the CRC
instruction set included in the latest Intel® Xeon® processors, CRC validation is possible with minimal impact
to network throughput while delivering superior data integrity.
The DONGWE DW-LCI82599-2SFP+ server adapters do it all 10 Gigabit LAN, FCoE, and iSCSI; truly
delivering on the promise of unified networking.
Reliable Performance
The family of DONGWE DW-LCI82599-2SFP+ 10G server adapters include a number of advanced features
that allow it to provide industry-leading performance and reliability.
Security Optimizations
The adapters support IPsec offload for Microsoft’s Network Access Protection (NAP), Active Directory,* and
future security capabilities in Windows* 7. An DONGWE 10G server adapter allows customers to run a
secure network environment without sacrificing performance.
PCIe v2.0 (5 GT/s)
PCIe v2.0(5GT/s) support enables customers to take full advan- tage of 10 GbE by providing a maximum of
20Gbps bi-directional throughput per port on a single dual port card.
Designed For Multi-core Processors
Support for technologies such as multiple queues, receive-side scaling, multiple MSI-X vectors, and Low
Latency Interrupts
allow the DONGWE DW-LCI82599-2SFP+10G server adapter to provide high-performance, 10 Gigabit
connectivity in multi-core server blades. These technolo- gies distribute network processing across multiple
CPU cores, improving overall performance.
