Intel continues its legacy of Ethernet leadership by introducing a 40 gigabit family of adapters powered by, the Intel Ethernet XL710 Controller, codenamed Fortville.
The XL710 adapter family addresses the demanding needs of the next-generation agile data center by providing unmatched features for both server and network virtualization, flexibility for L AN and SAN networks,and proven, reliable performance.
Leading 10/40 GbE Performance
Optimized performance vectors (and key uses) include:
1 Small Packet Performance:Maintains wire-rate throughput on smaller payload sizes (>128 Bytes for 40 GbE and >64 Bytes for 10 GbE
2 Bulk Transfer Performance:Delivers line-rate performance with low CPU usage for large application buffers
3 Virtualized Performance:Alleviates hypervisor I/O bottlenecks by providing flow separation for Virtual Machines (VMs)
4 Network Virtualization:Network virtualization overlay offloads including Geneve, VXLAN, and NVGRE
5 Storage Performance:Enables competitive performance with native OS drivers and intelligent offload for NAS (NFS, SMB), and SAN (iSCSI and 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)1—providing a one-wire solution with virtual pipes for the different classes of traffic:
1 Data: Best effort delivery of standard L AN traffic
2 Storage: Losslessnetwork for FCoE and iSCSI
3 Management: Guaranteed connectivity of data center
One Adapter, One Price
With the Intel adapters, iSCSI and FCoE support are included in the price of an adapter. There is no need to purchase multiple adapters or additional licensing for an XL710 adapter. It is simple and easy. Everything you need to unify your networking is included in a single SKU. One adapter, one price.
Power efficiency is critical to IT specialists as energy consumption is a real OpEx concern.
1 Lowest Power Consumption: The new generation of XL710 adapters are power misers. They deliver double the throughput with only half the power of the previous X520 generation.
2 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 Virtualization Technology (Intel VT), the XL710 family of adapters 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:
1 VMDq for Emulated Path: Adapter-based VM Queue sorting enabling efficient hypervisor-based switching
2 Virtualized Performance: Alleviates hypervisor I/O bottlenecks by providing flow separation for Virtual Machines (VMs)
3 Network Virtualization: Network virtualization overlay offloads including Geneve, VXLAN, and NVGRE
4 Storage Performance: Enables competitive performance with native OS drivers and intelligent offload for NAS (NFS, SMB), and SAN (iSCSI and FCoE)
5 SR-IOV for Direct Assignment: Adapter-based isolation and switching for various virtual station instances enabling optimal CPU usage in virtualized environments
Additionally, XL710 adapters provide Virtual Bridging1 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:
1 VEPA1:IEEE 802.1Qbgsupport for Virtual Ethernet Port Aggregator1
2 VEB: Virtual Ethernet Bridge support via Intel VT
Network virtualization is the next big trend in creating an agile data center. The family of XL710 adapters are ready to help you take that next step.
1 VXLAN, NVGRE, Geneve Offloads: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 checksum 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 received 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 increases 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 Intel Xeon processor where appropriate and implement 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:
2 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.
3 Host iSCSI/FCoE Initiators: Providing exceptional performance without the need for full-offload HBA methods.
4 Flow Classification: Trafficking data flows across multiple consumers and connections
The XL710 family of adapters 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.
