To deploy Synchronous DR (also known as Metro DR) setup, you need to install a single stretched Portworx cluster across two clusters. A single Portworx clusters spans across an on-premise environment with a maximum latency of 10 ms.

The following diagram shows a synchronous DR setup involving two clusters in the same metropolitan area network:

This document explains how to install a stretched Portworx cluster and achieve synchronous DR. It will demonstrate how to failover and failback applications between two clusters.

Perform the following steps to set up synchronous DR:
