Based on the new Intel® 82580 Gigabit Ethernet Controller, the Intel® Ethernet I340 Server Adapter is Intel’s fourth generation of PCIe GbE adapter. This adapter showcases the industry’s first fully integrated quad-port PCIe Gen2 GbE controller, providing a smaller footprint and lower power dissipation. In addition, the Intel® Ethernet I340 Server Adapter offers advanced features, including support for multi-core processors and server virtualization, as well as a scalable PCI Express Gen 2.0 interface. Intel’s first eco-friendly halogen-free board combines low-power and cost for the best price/performance ratio in a quad-port solution available today.
Working to create a more environmentally sustainable future, Intel is pleased to introduce its first halogen-free Ethernet Server Adapter. The transition to halogen-free products is not government mandated, but driven by Intel’s goal to eliminate the use of environmentally sensitive materials. The move to halogen-free products marks another step in our continual march toward minimizing the environmental footprint of Intel’s products, processes, and technologies.
Designed for Multi-Core Processors
This quad-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 Intel® QuickData Technology, MSIX, 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.
Support for iSCSI
The server adapter provides support for proven OS and VMM iSCSI initiators as well as iSCSI boot. Historically, CRC32C computation has degraded system performance, but not with the CRC instruction set included in the latest Intel® Xeon® processors. CRC validation is possible with minimal impact to the network throughput while delivering superior data integrity .
Support for Virtualization
The Intel® Ethernet I340 Server 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: Product Brief Intel® Ethernet I340 Server Adapter Network Connectivity Intel® Ethernet I340 Server Adapter Quad-port Gigabit Ethernet server adapter designed for multi-core processors and support for Virtualization & Unified Storage Environments • Virtual Machine Device Queues (VMDq) • Intel® I/O Acceleration Technology (Intel® I/OAT) Use of multi-port adapters in a virtualized environment is very important because of the need to provide redundancy and data connectivity for the applications/workloads in the virtual machines. Due to the need for redundancy and data connectivity, it is recommended that a virtualized physical server needs at least six GbE ports to satisfy the I/O requirement demands.
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.
Intel® I/O Acceleration Technology
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 Intel QuickData Technology, Direct Cache Access (DCA), MSI-X, Low-Latency Interrupts, Receive Side Scaling (RSS), and others. Intel QuickData Technology, a DMA engine, moves data using the chipset instead of the CPU. DCA enables the adapter to pre-fetch data from the memory cache, thereby avoiding cache misses and improving application response times. 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. Reliable Performance The server adapter includes a number of advanced features that enable it to provide industry-leading quad-port 1GbE performance and reliability. PCIe* v2.0 (5 GT/s) PCIe v2.0 (5 GT/s) support enables customers to take full advantage of the 1 GbE by providing a maximum of 2.0 Gbps bi-directional throughput per port on a single quad-port card. For today’s demanding virtualized data center environments, the new Intel® Ethernet I340 Server Adapter delivers ultimate flexibility and scalability.
