The LREC9702HT Server Adapter is fourth generation of PCIe GbE adapter. This adapter showcases the industry’s first fully integrated dual-port PCIe Gen2 GbE controller, providing a smaller footprint and lower power dissipation. In addition, the LREC9702HT Server Adapter offers advanced features, including support for multi-core processors and server virtualization, as well as a scalable PCI Express Gen2.0 interface. Intel’s first eco-friendly halogen-free board com- bines low-power and cost for the best price/performance ratio in a dual-port solution available today.

Designed for Multi-Core Processors

This dual-port adapter provides high-performing, multi-port Gigabit connectivity in a multi-core platform as well as in a virtualized environment. In a multi-core platform, the adapter supports technologies such as MSI-X, and Low Latency Interrupts that help accelerate data across the platform, improving application response times.

The I/O technologies on a multi-core platform make use of the multiple queues and multiple interrupt vectors available on the network controller. These queues and interrupt vectors help in load balancing the data and interrupts amongst themselves in order to lower the load on the processors and improve overall system performance. For example, depending upon the latency sensitivity of the data, the low latency interrupts feature can bypass the time interval for specific TCP ports or for flagged packets to give certain types of data streams the least amount of latency to the application.

Intel I/O Acceleration Technology (Intel I/OAT) is a suite of features that improves data acceleration across the platform, from networking devices to the chipset and processors, which helps to improve system performance and application response times. The different features include MSI-X, Low-Latency Interrupts, Receive Side Scaling (RSS), and others. MSI-X helps in load-balancing I/O interrupts across multiple processor cores, and Low Latency Interrupts can provide certain data streams a non-modulated path directly to the application. RSS directs the interrupts to a specific processor core based on the application’s address.

Support for iSCSI

LR-LINK LREC9702HTserver adapters with native iSCSI initiators built into Microsoft® Windows®, Linux®, and VMware® ESX platforms provide a simple, dependable, cost-effective way to connect to LANs and 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 Intel Ethernet server adapters for iSCSI allows administrators to use a single initiator, TCP/IP stack, and set of management tools and IT policies. In addition, the LR-LINK LREC9702HT server adapter includes a number of hardware features designed to accelerate iSCSI traffic and enhance data processing. For example, TCP segmentation offload, Receive side coalescing (RSC), and checksum offload capabilities help reduce processor utilization, increase throughput, and deliver exceptional iSCSI performance. The adapters are designed to flexibly scale workloads across multi-core processor–based systems. Finally, using native OS initiators, an LR-LINK LREC9702HT Server Adapter enables support for the CRC-32 digest instruction set included in the Intel Xeon® processor 5500 series, which improves transmission reliability and thus delivers an enterprise class iSCSI solution for the IT customer.

Optimized for Virtualization

The LR-LINK LREC9702HTServer Adapter showcases a suite of hardware assists that improves overall system performance by lowering the I/O overhead in a virtualized environment. This optimizes CPU usage, reduces system latency, and improves I/O throughput. These features include:

Virtual Machine Device Queues (VMDq)

Intel I/O Acceleration Technology (Intel I/OAT)

Virtual Machine Device queues (VMDq)

VMDq reduces I/O overhead on the hypervisor in a virtualized server by performing data sorting and coalescing in the network silicon. VMDq technology makes use of multiple queues in the network controller. As data packets enter the network adapter, they are sorted, and packets traveling to the same destination (or virtual machine) get grouped together in a single queue. The packets are then sent to the hypervisor, which directs them to their respective virtual machines. Relieving the hypervisor of packet filtering and sorting improves overall CPU usage and throughput levels.

Reliable Performance

The server adapter includes a number of advanced features that enable it to provide industry-leading dual-port 10/100/1000Mbps performance and reliability.

PCIe v2.0 (5GT/s)

PCIe v2.0 (5GT/s) support enables customers to take full advantage of the 10/100/1000Mbps by providing a maximum of 2.0 Gbps bidirectional throughput per port on a dual-port card.

For today’s demanding virtualized data center environments, the new LR-LINK LREC9702HT Server Adapter delivers ultimate flexibility and scalability.
