Portworx Guided Hands On-Labs. Register Now


Customers choose Portworx to automate data management. With the rapid rise of Kubernetes, enterprises are increasingly looking for cloud-native ways to solve the challenges of persistent storage for containers. Additionally, along with public cloud, one of the most popular platforms for customers running containers continues to be VMware virtual machines, more and more with Pivotal Kubernetes Service (PKS) providing a native Kubernetes-integration to VSphere. In this most recent release of Portworx, we update both our ability to automate storage management and our integration with VMware and PKS. PX-Enterprise 1.6 gives our customers the agility needed to support highly dynamic and complex containerized environments with the following key features:

SDK to Automate Cloud Native Storage and Data Management

The very definition of programmable infrastructure is that server, network and I/O resources can be accessed, provisioned and configured on demand using an API. Doing this for storage means being able to handle the transient nature of disks, nodes and networks in cloud infrastructure. As such, the storage stack must be able to handle situations where –

  • Nodes may gain/lose disks, RAM, network interfaces
  • Disk may gain IOPS, Size, etc. on the fly
  • Number of nodes / regions / zones changes

With the brand new software development kit for OpenStorage (Portworx’s open source control plane solution), PX-Enterprise provides a programmable storage system integrated with application workflows. Without any outside help, developers will be able to programmatically determine how storage is allocated, consumed, encrypted, backed up and managed across multi-cloud environments. To further automate processes and workflows, they will now be able to define I/O levels, how snapshots are created, and how migration to different server clusters or different clouds is managed. All in all, the new SDK allows them to meet their unique business needs by closely integrating application and data management workflows programmatically.


As shown in the architecture above, the OpenStorage SDK is based on gRPC, allowing clients to be automatically generated in multiple languages satisfying language requirements for our customers. The SDK also provides a gRPC REST Gateway which automatically changes REST requests to gRPC. More information about this architecture including installation, tutorial and API reference can be found here.

Integration with vSphere and PKS

In public cloud environments, auto-scaling storage along with compute has been a big boon for customers as it enables them to elastically scale the infrastructure depending upon business needs. It has not been that straightforward for private cloud users who use vSphere and are now adopting Kubernetes for containerized workloads.

PX-Enterprise 1.6 adds automatic storage provisioning for vSphere and PKS private clouds. This allows vSphere users to decouple compute from storage and scale compute without worrying about data availability or migration. Any stateful application running on PKS cluster can now be scaled up and down seamlessly when backed by Portworx volumes as shown below.


This feature works for both scenarios when customers are using local datastores or shared datastores with vSphere as described here. This drastically simplifies operations in private clouds for automating deployment and scaling by specifying the storage requirements using standard Kubernetes deployment specifications.

Documentation and release notes for PX-Enterprise 1.6 are available here. To our customers who helped contribute to this release by providing use cases and requirements or by testing early versions, we’d like to say a sincere thank you! To everyone else, we hope you’ll try it out and tell us what you think.
