Synchronous DR for Kubernetes

Portworx supports synchronous (Metro) DR when installed as a single stretch cluster across multiple Kubernetes clusters. The Kubernetes clusters need to span across a metropolitan area network with a maximum latency of 10 ms. This document explains how to install a stretch Portworx cluster and achieve synchronous DR. It will demonstrate how to failover and failback applications between two Kubernetes clusters.

Perform the following steps to set up Metro DR:


  • The sections of this document require specifying a <namespace>, you should update this to the namespace where Portworx is installed in your environment.
  • A maximum replication factor of 2 is supported in a Metro-DR deployment. Using repl: 3 might cause downtime because of a loss of volume quorum.
