Halogen-Free

Working to create a more environmentally sustainable future, Intel is pleased to introduce its first 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 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 steams 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 iSCI

Intel Ethernet server adapters with native iSCI initiators built into Microsoft, Windows, Linux and VMware ESX platforms provide a simple, dependable, cost-effective way to connect to LANs and iSCI 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 iSCI allows administrators to use a single initiator, TCP/IP stack and set of management tools and IT policies. In addition, the I340 server adapter includes a number of hardware features designed to accelerate iSCI 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 iSCI performance. The adapters are designed to flexibly scale workloads across multi-core processor-based systems. Finally, using native OS initiators, an Intel Ethernet I340 server adapter enables support for the CRC-32 digest instruction set included in the Intel Xeon processor 500 series, which improves transmission reliability and thus delivers an enterprise class iSCI solution for the IT customer.

Optimized for Virtualization

The Intel Ethernet I340 server adapter showcases a suite of hardware assists that improves overall system performance by lowering 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)
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 travelling 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.
