ATTO FastFrame N4S2 10GbE PCIe 3.0 x8 2-Port SFP+ Low Profile network card

SKU CH-JM9X-MWM93

Dual-port 10 GbE SFP+ SmartNIC on PCIe 3.0 x8 with ATTO 360 management for media, HPC and AI workloads

  • 10 GbE dual-port connectivity via PCIe 3.0 x8
  • Low-profile bracket fits space-constrained servers
  • SFP+ optical ports support 10GBase-X fibre links
  • ATTO 360 utility simplifies tuning and monitoring
  • Trusted for over 30 years in media and HPC workloads

10GbE Dual-Port SmartNIC

The ATTO FastFrame N4S2 is a low-profile network adapter with two SFP+ ports for optical fibre. It connects through a PCI Express 3.0 x8 slot and delivers 10GbE line speed. The card targets media workflows, high-performance computing clusters and data-intensive storage environments.

Upgrade from single-port 10GbE or 1GbE links

Adding a second 10GbE port doubles aggregate bandwidth and provides link redundancy for critical workloads. The jump is worth it when workstations or servers need concurrent high-throughput streams for video finishing, archiving or AI data ingestion without saturating a single connection.

Verify PCIe 3.0 x8 slot

Confirm the host system has an available PCI Express 3.0 x8 slot with enough physical clearance for a low-profile bracket. Ensure SFP+ optics or direct-attach cables match the required reach and fibre type, and that the operating system supports ATTO 360 management utilities for tuning and monitoring.

Questions about this item

Does the PCI Express 3.0 x8 slot provide enough bandwidth for both 10GbE ports?

The x8 lane configuration delivers ample throughput for dual 10GbE line-rate traffic.

What bracket height is required to install this card in a 1U server?

The low-profile bracket fits standard 1U chassis; swap to the included full-height bracket for towers.

Are SFP+ transceivers included or must they be purchased separately?

Transceivers are not included; choose 10GBase-SR, LR or compatible third-party SFP+ modules.
