Before you can deploy the available data services in PDS, you need to login with valid Admin credentials and add a Kubernetes cluster to PDS. However, in order to use your cluster with PDS, you need to first install Portworx Enterprise in your environment.
For more information about the minimum requirements to install Portworx Enterprise, refer to the Prerequisites page.
This topic includes the recommended hardware, network, software, Kubernetes requirements specifically to use PDS.
The minimum supported size for a Portworx cluster is three nodes. Each node must meet the PDS prerequisites:
Refer to the Portworx Enterprise installation prerequisites section for minimum drive requirements.
Refer to the Portworx Enterprise installation prerequisites section for backing drive requirements.
Refer to the Portworx Enterprise installation prerequisites section for storage drives requirements.
