Announcing PX-CSI Compatibility and Interoperability Matrix

PX-CSI Compatibility and Interoperability Matrix

We’ve launched a new Compatibility Matrix on the PX-CSI docs site to make version validation and feature planning easier.

Why did we build this?

Until now, our customers had to cross-reference multiple docs and tables across our product offerings to figure out whether a specific combination of product versions for the features they are interested in:

  • PX-CSI
  • FA/FB Purity
  • Portworx operator
  • Kubernetes platform

There was no easy way to surface feature constraints. For example, Secure Multi-Tenancy and ActiveCluster are not supported together currently with PX-CSI, but they often discover that only after diving deep into feature documentation or after deploying the required config.

What’s new?

The new matrix has two modes:

  • Reference View – Full compatibility matrix with supported backends, Kubernetes platforms, features, and version requirements in one place.
  • Compatibility Calculator – Interactive mode where users select their backend, platform, and required features. The tool then calculates:
    • Minimum required versions
    • Latest supported versions
    • Compatibility constraints

Highlights

  • Automatically considers support policy and recommend actively supported PX-CSI versions
  • Handles mutually exclusive features directly in the UI
  • Explains compatibility restrictions clearly
  • Driven entirely from a single YAML data source for easier maintenance

How to use it?

Open the Compatibility Matrix page in the PX-CSI docs. The Compatibility Calculator opens by default.

Select your:

  • Storage backend
  • Kubernetes platform
  • Required features

The recommendations update dynamically as you make selections.

Expected impact

  • Faster self-service compatibility checks
  • Fewer support questions
  • Less manual maintenance of scattered version tables
  • Easier updates when support policies or feature compatibility changes

We’ll continue to improve this based on the feedback. Please give it a spin and let us know how it goes.
