ATTO Technology FastFrame N422 25Gbps PCIe 3.0 x8 network card FFRM-N422-000

SKU CH-8YW1-GEM5V MPN FFRM-N422-000

Dual-port 25 Gbps PCIe 3.0 x8 Ethernet card with SFP28 fibre connectors and low-profile bracket

  • Speed25Gbps
  • InterfacePCI Express 3.0 x8
  • Low-latency 25 Gbps Ethernet for data-intensive workloads
  • PCIe 3.0 x8 interface provides high-throughput server connectivity
  • Dual SFP28 ports enable flexible optical-fibre deployment
  • ATTO 360 software simplifies tuning, monitoring and diagnostics
  • TAA-compliant, US-built with 30-year enterprise heritage

Target Workloads

The ATTO FastFrame N422 is a dual-port 25Gbps Ethernet adapter built for enterprise datacentre, cloud, AI/ML and media workflows. It delivers low-latency, high-efficiency connectivity for data-intensive and real-time environments. The card supports macOS, Windows and Linux operating systems. It is not suited for desktop users who only need 1GbE or 10GbE connectivity.

Deciding Specification

The card uses a PCI Express 3.0 x8 host interface and provides two SFP28 ports running at 25Gbps each. This combination of slot width and port speed determines whether the adapter fits the server platform and matches the network fabric. Buyers whose systems lack a PCIe 3.0 x8 slot or who require 100GbE line rates cannot use this model.

Thermals, Noise and Power

The low-profile bracket allows installation in dense 1U and blade chassis where airflow is managed by the server fans. As a passive plug-in card it adds no active cooling noise and draws power only from the PCIe slot. Typical enterprise deployments see the adapter operate within standard server thermal envelopes without additional cooling requirements.

Questions about this item

How does the 25Gbps per-port speed hold up inside a real server?

Each of the two ports runs at 25Gbps line rate, and the PCI Express 3.0 x8 host interface supplies sufficient throughput for both ports simultaneously without bottlenecking the data path.

What does the PCI Express 3.0 x8 interface cap in practice?

The x8 electrical connection sets the maximum host-bus bandwidth available to the card, defining the ceiling for combined ingress and egress traffic across both SFP28 ports.

What physical space and bracket does the card need to fit?

It uses a low-profile bracket and a standard PCIe plug-in form factor, so it installs in any low-profile or full-height slot with a matching x8 or wider connector.
