# Connect Three DGX Spark in a Ring Topology
> Connect and set up three DGX Spark devices in a ring topology
Configure three DGX Spark systems in a ring topology for high-speed inter-node communication
using 200GbE direct QSFP connections. This setup enables distributed workloads across three
DGX Spark nodes by establishing network connectivity and configuring SSH authentication.
**Outcome**: You will physically connect three DGX Spark devices with QSFP cables, configure network
interfaces for cluster communication, and establish passwordless SSH between nodes to create
