ATTO FastFrame N424 – Product Overview
Four-Port 25Gb Ethernet
The FastFrame N424 provides four independent SFP28 Ethernet ports for dense 25GbE connectivity in storage servers, media workstations and high-performance network infrastructure.
PCIe 4.0 x16 Host Interface
An x16 PCIe 4.0 host connection gives the adapter the host-side bandwidth required for four active 25GbE links and demanding multi-stream workloads.
Storage And Compute Offloads
FastFrame hardware accelerates common networking tasks including checksum processing, segmentation offload, packet filtering, virtualisation and RoCE, reducing host CPU overhead in latency-sensitive environments.
ATTO Networking Software
ATTO360 Networking provides tuning, monitoring and diagnostics, while ATTO Ethernet Suite supplies the appropriate platform driver stack. The N424 supports Windows, Linux and macOS environments documented by ATTO.
