A Complete, Unified Networking Solution
Converging data and storage onto one fabric eliminates the need for multiple adapters, cables and switches.
Furthermore both 10 and 40 gigabit Ethernet provides the bandwidth to converge these multiple fabrics onto a single wire. A key capability that makes all this possible is traffic class separation provided by Data Center Bridging (DCB) —providing a one-wire solution with virtual pipes for the different classes of traffic:
• Data: Best effort delivery of standard LAN traffic
• Storage: Lossless network for FCoE and iSCSI
• Management: Guaranteed connectivity of data center IP management
Power efficiency is critical to IT specialists as energyconsumption is a real OpEx concern.
• Lowest Power Consumption
The new generation of LREC9804BF-4SFP+ adapters are powermisers. They deliver double the throughput with only
half the power of the previous LREC9802BF-2SFP+
• Energy Efficient Ethernet (EEE)
Reduces power consumption during periods of low data activity. Energy is used to maintain the physical layer transmitters in a “ready state” to transmit data on the wire. During periods of low data traffic, EEE sends a low-power-idle signal to put the transmitters into a “low power state” saving power and cost. When data needs to be sent, EEE sends a normal idle signal to wake up the transmit system before data is due to be sent so there is no degradation of performance.
With Intel VirtualizationTechnology (VT), the LREC9804BF-4SFP+ adapter deliver outstanding I/O performancein virtualized server environments. They reduce I/O bottlenecks by providing intelligent offloads for networkingtraffic per virtual machine (VM), enabling near-nativeperformance and VM scalability. The host-based virtualization technologies supported by Intel VT include:
• VMDq for Emulated Path:
Adapter-based VM Queuesorting enabling efficient hypervisor-based switching
• SR-IOV for Direct Assignment:
Adapter-based isolationand switching for various virtual station instancesenabling optimal CPU usage in virtualized environments. Additionally, LREC9804BF-4SFP+ provide Virtual Bridgingsupport that delivers both host-side and switch-sidecontrol and management of virtualizedI/O as well asthe following modes of virtualized operation:
VEPA : IEEE 802.1Qbg support for Virtual EthernetPort Aggregator
VEB: Virtual Ethernet Bridge support via Intel® VT
Network virtualization is the next big trend in creating anagile data center. The LERC9804BF-4SFP+adapter is ready
to help you take that next step.
• VXLAN, NVGRE, GENEVE Offloads:
These statelessoffloads preserve application performance for overlaynetworks. With these offloads it is possible to distributenetwork traffic across CPU cores.At the same timeXL710 offloads LSO, GSO, and check-sum from the host software reducing CPU overhead.
Intel® Ethernet Flow Director
Flow Director is an advanced traffic steering capability built into the XL710 controller. It consists of a large number of flow affinity filters that direct receive packets by their flows to queues for classification, load balancing, and matching between flows and CPU cores. It eliminates context switching required within the CPU. As a result, Flow Director significantly increasing the number of transactions per second and reduces latency for cloud applications like Memcached.
The Intel Xeon processor family has demonstrated increased computing performance and increased integration of key server subsystems generation after generation. To offload is to leverage the ever-escalating computing power of the Xeon processor where appropriate and implementing complementary accelerations in the network controller—this is what Intel refers to as ”intelligent offloads.” By employing a balanced hybrid of compute and offload, intelligent offloads are able to achieve the optimized point of performance and efficiency. This is most notably observed in the following usage models:
• TCP Stateless Offloads:
Demonstrates leading performance vs. TOE solutions without restricting featureusage (TOE usage usually requires that key featuresbe disabled). Supported stateless offloads includeChecksum, TSO, VMDq, and RSS.
• Host iSCSI/FCoE Initiators:
Providing exceptionalperformance without the need for full-offloadHBA2 methods.
• Flow Classification:
Trafficking data flows acrossmultiple consumers and connections.
LREC9804BF-4SFP+ also incorporate the manageability required by IT personnel for remote control and alerting. Communication to the Board Management Controller (BMC) is available either through an on-board SMBus port or the DMTF-defined NC-SI, providing a variety of management protocols, including IPMI, BMC Pass-thru, OS2BMC, and MCTP/SMBus and MCTP/PCIe.
