ATTO's comprehensive line of FastFrame products includes single port 40GbE models suitable for a wide variety of high-performance applications, and provides the high-quality and high-performance experience ATTO customers are accustomed to.

The ATTO FastFrame dual-port NQ42 Optical Ethernet Adapter draws less power than competing solutions while providing faster throughput, meaning users can transfer more data at a lesser cost than the competition, enhancing the Total Cost of Ownership of the NQ42. Includes QSFPs.

In addition to broad support for Windows and Linux server and desktop operating systems, ATTO is a leader in high performance I/O connectivity for macOS environments.

ATTO FastFrame 40Gb Ethernet NICs Adapters

ATTO FastFrame 40GbE network interface cards (NICs) are designed to enable full-utilization of 40GbE bandwidth with low-latency remote direct memory access (RDMA) over converged ethernet support. FastFrame NICs use less power than other 40GbE NICs, providing a higher ROI by transferring more data per dollar spent on power than the competition.

Technical Features

  • Single- and daul-port configurations
  • QSFP+ connectors (QSFP modules included with -000 models)
  • Up to 40Gb/s throughput per port
  • High-performance x8 PCIe 3.0 bus
  • Low profile form factor
  • Driver support for Windows, Linux and macOS operating systems
  • RDMA over Converged Ethernet (RoCE) enables industry-leading low latency (1us MPI ping latency) and decreases CPU utilization
  • TCP/UDP/IP hardware-based stateless offloads
  • SR-IOV technology dedicates adapter resources for virtual machines within servers
  • Guaranteed bandwidth and low-latency services
  • Energy efficient Ethernet enables lowest power draw on the market for a 40GbE NIC
  • Hardware-based I/O virtualization

Optimized for Data Center Applications

With full support for TCP/IP, UDP, iSCI, Fibre Channel over Ethernet plus RDMA over Converged Ethernet (RoCE), ATTO FastFrame 40GbE NICs deliver the bandwidth needed at the core of today's data centers. While most TCP-based 40GbE NICs only achieve a maximum 23Gb/s bandwidth, the RoCE feature on FastFrame 40GbE NICs enables near line-rate performance via direct memory transfer over Layer 2 Ethernet.

Best-in-class energy efficiency and single route input/output virtualization technology for enhanced virtualization support make ATTO FastFrame 40GbE NICs ideal for a wide variety of data center use cases. In addition, their industry-leading low latency powers optimal performance for applications such as high performance computing clusters while simultaneously minimizing CPU utilization.

Performance Engineered for High-Resolution Digital Video

Bandwidth reductions caused by transmission control protocol overhead make many competing 40GbE NICs incapable of supporting 8K video. ATTO FastFrame 40GbE NICs, in contrast, utilize RoCE to free up the full 40GbE pipeline, providing sufficient bandwidth for a single uncompressed 8K stream or for multiple 4K video streams.


ATTO FastFrame 40GbE NICs combine 40GbE technology with the lossless benefits of Enhanced Ethernet and robust software iSCSI initiators to meet the performance and efficiency needs of today's growing data centers. FastFrame 40GbE NICs are specifically built for applications that require low-latency, high-bandwidth data transfers, including HPC clusters, cloud environments, rackmount servers in data centers and high-resolution 4K and 8K video.


Powerful solution. Powerful design.

Based on industry-standard Ethernet technology, ATTO FastFrame NICs are available in single, dual, and quad-port configurations. FastFrame has been proven to deliver high performance I/O connectivity and lossless Ethernet support for improved iSCSI block storage access as well as optimal network traffic.

Connectivity across campusConnectivity across campus

ATTO FastFrame NICs make it possible to setup virtual networks across campus or the data center. Using optical fiber and a transceiver (SFP+), Ethernet packets can now travel up to 400m without sacrificing speed or data quality.

Flexible connectivity

ATTO FastFrame NICs provide the most flexible and scalable connectivity for today's data center environments. By leveraging data center bridging and support for software iSCSI initiators, FastFrame network adapters offer the ability to support both local and storage area networks.

Meet the demands of 6K Today.

Migrate to higher performance levels with FastFrame 40GbE and 10GbE NICs. FastFrame is used for demanding applications using streaming media like post production and video/sound editing, and other rich media and data intensive applications.


RoCEData transfers just got faster.

ATTO 40GbE NICs feature industry-leading latency management with RoCE. It has the benefit of eliminating the intermediate step of utilizing the CPU to transfer data and enabling near line-rate performance.

The smoothest and most reliable data transfers

Sometimes it is not just how fast you move the data, but how well you can manage the flow of that data to reduce network collisions. With distinctive latency-management features such as ATTO Advanced Data Streaming (ADS), FastFrame adapters deliver better overall performance across all of your applications while reducing your CPU utilization significantly.

Advanced Data Streaming (ADS)

Do more. Save more.

ATTO FastFrame NICs are the lowest energy consuming cards on the market and provide a higher ROI by transferring more data per dollar spent on power than the competition. One 40GbE NIC can do the same amount of work as four 10GbE cards with less power consumption and overhead.

Low Power Consumption


High compatibility and broad interoperability

ATTO FastFrame NICs work wherever you need them: in workstations, servers, and data center racked servers. They are supported by a full suite of software drivers for macOS, Windows and multiple Linux distributions.
