Marvell® Teralynx® 7
(IVM777xx / IVM775xx / IVM773xx)
The Teralynx 7 family is Marvell’s programmable Ethernet switch silicon scaling from 3.2 Tbps to 12.8 Tbps, covering ToR, leaf, and high-radix spine deployments. Built for cloud, enterprise, HPC, and service provider data centers, it combines large buffers, ultra-low latency, and line-rate programmability with industry-leading power efficiency — 2× performance-per-watt over alternatives. Open SDK and SAI APIs enable native SONiC support with a common software stack shared across the entire Teralynx product line.
Architecture & performance
- TeraSCALE™ switch and buffer fabric — scalable from 3.2 Tbps to 12.8 Tbps within a unified architecture, enabling ToR, leaf, and spine in a single silicon family
- Large shared packet buffer with dynamic thresholds for superior microburst (µBurst) absorption under heavy east-west load Cut-through latency of ~500 ns; industry-leading 2× performance-per-watt advantage over alternatives Up to 128 × 100G, 64 × 200G, or 32 × 400G single-chip configurations; multi-chip chassis scales to 256 × 400G (1024 × 100G)
SerDes & port flexibility
- IVM77700 / IVM77610: 50G PAM4 SerDes — industry’s first high-port-count 200G and 400G connectivity; supports 10/25/40/50/100/200/400 GbE
- IVM77500 / IVM77310: 25G NRZ SerDes — supports 10/25/40/50/100 GbE with full backward compatibility
- Up to 256 SerDes (IVM77700/IVM77500); proven robust interoperability across all speed grades
Programmable forwarding
