LREC9804BF-4SFP+ is LR-LINK a new generation of high-performance server adapter, based on the Intel XL710-BM1 controller. The Server Adapter addresses the demanding needs of the next-generation agile data center by providing unmatched features for both server and network virtualization, flexibility for LAN and SAN networks and proven, reliable performance.


The LREC9804BF-4SFP+ adapter delivers superior performance in a PCI Express v3.0 x8 slot. Optimized performance  vectors and key uses include:

Small Packet Performance:  

Achieves wire-rate throughput on smaller payload sizes ((>128 Bytes for 40 GbE and >64 Bytes  for 10 GbE)

Bulk Transfer Performance:  

Delivers line-rate performance with low CPU usage for large application buffers

Network Virtualization:  

Network virtualization overlay offloads including Geneve, VXLAN, and NVGRE

Storage Performance:  

Enables competitive performance with native OS drivers and intelligent offload for NAS (NFS, SMB), and SAN (iSCSI and FCoE)


Key Features

• Quad –Port 10GbE Server Adapter

• PCI Express* (PCIe) 3.0, x8

• Exceptional Low Power Adapters

• Network Virtualization offloads including Geneve, VXLAN  and NVGRE

• Intel® Ethernet Flow Director for hardware based application traffic steering

• Intel® Data Plane Developer Kit (DPDK) optimized for efficient packet processing

• Excellent small packet performance for network appliances and Network Function Virtualization (NFV)

• Intelligent offloads to enable high performance with Intel® Xeon® processor-based servers

• I/O virtualization innovations for maximum performance in a virtualized server

• Unified networking providing a single wire support for LAN and storage: NAS (SMB, NFS) and SAN (iSCSI, FCoE)


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 Savings

Power efficiency is critical to IT specialists as energy consumption is a real OpEx concern.

 Lowest Power Consumption

The new generation of LREC9804BF-4SFP+ adapters are power misers. 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.


Server Virtualization

With Intel Virtualization Technology (VT), the LREC9804BF-4SFP+ adapter deliver outstanding I/O performance in virtualized server environments. They reduce I/O bottlenecks by providing intelligent offloads for networking traffic per virtual machine (VM), enabling near-native performance and VM scalability. The host-based virtualization technologies  supported by Intel VT include:

 VMDq for Emulated Path: 

Adapter-based VM Queue sorting enabling efficient hypervisor-based switching

 SR-IOV for Direct Assignment:  

Adapter-based isolation and switching for various virtual station instances enabling optimal CPU usage in virtualized environments. Additionally, LREC9804BF-4SFP+ provide Virtual Bridging support that delivers both host-side and switch-side control and management of virtualized I/O as well as the following modes of virtualized operation:

VEPA : IEEE 802.1Qbg support for Virtual Ethernet Port Aggregator

VEB: Virtual Ethernet Bridge support via Intel® VT


Network Virtualization

Network virtualization is the next big trend in creating an agile data center.  The LERC9804BF-4SFP+ adapter is ready

to help you take that next step.


These stateless offloads preserve application performance for overlay networks. With these offloads it is possible to distribute network traffic across CPU cores. At the same time XL710 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. 

Intelligent Offloads

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 feature usage (TOE usage usually requires that key features be disabled). Supported stateless offloads include Checksum, TSO, VMDq, and RSS.

 Host iSCSI /FCoE Initiators:  

Providing exceptional performance without the need for full-offload HBA2 methods.

 Flow Classification:  

Trafficking data flows across multiple 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.
