This topic includes the recommended hardware, network, software, Kubernetes requirements specifically to use PDS.

Installation prerequisites

The minimum supported size for a Portworx cluster is three nodes. Each node must meet the PDS prerequisites:





  • Minimum: 4 cores

  • Recommended: 8 cores


  • Minimum: 8 GB

  • Recommended: 16 GB


Refer to the Portworx Enterprise installation prerequisites section for minimum drive requirements.
