Portworx CSI Release Notes

Portworx CSI (PX-CSI) is a lightweight storage orchestration solution that uses the Kubernetes Container Storage Interface (CSI) framework to integrate the Pure Storage storage solutions.

PX-CSI integrates with Kubernetes to directly access Pure Storage FlashArray Direct Access volumes (FADA) and FlashBlade Direct Access volumes (FBDA).

If you're setting up PX-CSI for the first time, see Install Portworx CSI. If you're already using PX-CSI, upgrade to the latest version. For upgrade instructions, see Upgrade Portworx CSI.

For information about supported versions, release numbering, and support phases, refer to the PX-CSI Life Cycle Support Policy.
