ATTO ThunderLink NS-5254 – Product Overview
Thunderbolt 5 To Quad-Port 25GbE
The ThunderLink NS-5254 provides four independent 25GbE SFP28 links for high-bandwidth media, storage, backup and compute workflows that benefit from dense Ethernet connectivity.
Dedicated Thunderbolt Host And Device Ports
Two 80Gb/s Thunderbolt 5 USB-C ports provide dedicated host and downstream-device roles under ATTO's current ThunderLink 5 installation model.
Four 25GbE SFP28 Ports
Each Ethernet port supports a 25Gb/s data rate. ATTO's current product information states that SFP28 optical modules are included, but its Store packaging copy is inconsistent on the precise module quantity, so this page does not assert a count.
Networking Acceleration And Management
ATTO360 Networking provides tuning, monitoring and diagnostics. Hardware capabilities include SR-IOV, advanced packet filtering, VLAN/QoS functions, checksum and segmentation offloads, and RoCE v1/v2 RDMA support on supported Windows and Linux platforms.
