# Connect Multiple DGX Spark through a Switch
> Set up a cluster of DGX Spark devices that are connected through Switch
Configure four DGX Spark systems for high-speed inter-node communication using 200Gbps QSFP connections through a QSFP switch. This setup enables distributed workloads across multiple DGX Spark nodes by establishing network connectivity and configuring SSH authentication.
