Fully Featured Server Adapter

The dual-port N320E offers best-of-class performance and features, including IP/UDP/TCP checksum and large send offload, rate control and QoS, virtualization, and rule-based traffic steering and filtering.

Third-Generation Protocol Offload Engine

The N320E employs Chelsio’s unique third-generation Terminator 3 ASIC, a high-performance, programmable protocol processor. Terminator 3 processes all connections in a single datapath to deliver line-rate 10Gbps performance with one connection, up to thousands of connections. In contrast, competitive multi-RISC offload engines, which rely on having enough connections to distribute their process- ing among parallel processors to achieve full performance, are ulti- mately limited by the performance of each processor.

Robust, Proven Solution

Subjected to thousands of hours of compatibility testing, over two years of stress testing by several OEM test suites and production deployments in servers, storage systems and cluster computing, Chelsio’s robust, stable protocol offload technology delivers proven performance in a wide range of environments. The N320E is genera- tions ahead of competing products.

Software Drivers

Chelsio offers a full suite of protocol software and drivers for Linux and Windows with the N320E adapter.

N320E-CXA specifications

Chelsio Communications N320E-CXA is a high-performance network interface card designed to meet the demanding needs of data center environments. Featuring advanced capabilities, it is particularly well-suited for applications such as high-frequency trading, cloud computing, and big data analytics. The card supports a range of connectivity options, including 10G Ethernet, 25G Ethernet, and 40G Ethernet, ensuring flexibility and scalability as network requirements evolve.

One of the standout features of the N320E-CXA is its support for the latest Ethernet standards, including IEEE 802.3bz and IEEE 802.3ae. This ensures compatibility with a wide array of switches and routers, facilitating seamless integration into existing infrastructure. Additionally, the card is equipped with Chelsio’s T5 ASIC technology, which enables offloading of several critical tasks from the CPU. This offloading includes TCP segmentation, TCP checksum, and iSCSI processing, significantly enhancing overall system performance.

In terms of technologies, the N320E-CXA employs Unified Wire technology, which allows it to support multiple protocols, including TCP/IP, iSCSI, and RDMA (Remote Direct Memory Access) over Converged Ethernet (RoCE). This flexibility makes it an ideal solution for converged network environments where both storage and computing resources must be efficiently managed. The card also provides support for virtualized networking environments through its advanced SR-IOV (Single Root I/O Virtualization) capabilities, enabling multiple virtual machines to share the same physical NIC without compromising performance.

The N320E-CXA is designed with energy efficiency in mind, featuring power management features that reduce overall power consumption while maintaining high throughput. This is increasingly important in modern data centers where operational costs and environmental impact are critical considerations.

In summary, the Chelsio Communications N320E-CXA is a robust and versatile network interface card that combines cutting-edge performance with advanced technologies. Its high-speed connectivity, support for a wide range of protocols, and efficient offloading capabilities make it an exceptional choice for organizations looking to optimize their network performance and scale their operations effectively. Whether it’s in a cloud computing environment or in high-demand data-intensive applications, the N320E-CXA stands out as a reliable and powerful networking solution.
