4x 400G QSFP-DD high-density switch for ultra-fast local clusters
Hardware
In plain English
A supercharged 400 Gbps network switch that gives clustered AI workstations 4x more bandwidth than 100G, cutting node communication lag.
Technically
A 4-port 400G QSFP-DD switch delivering 3.2 Tbps aggregate non-blocking switching throughput. Enables 200G/400G RoCEv2 direct interconnects between high-end DGX Spark and workstation clusters for near-zero tensor parallelism latency.
