Portworx, a container storage and data management provider, released version 2.1 of its enterprise platform and said that it has raised $27 million in an oversubscribed series C funding round. The round roughly doubles the amount that the company has raised to $55.5 million.

The funding round is being led by Sapphire Ventures and the venture arm of Mubadala Investment Company. Returning investors are Mayfield Fund and GE Ventures. New funding is coming from Cisco Investments, HPE and NetApp.

Version 2.1 of PX-Enterprise, which is Portworx’s cloud-native storage product for Kubernetes, adds security and disaster recovery features to the platform. The new features, which will be available on April 20, include role-based access controls. Organizations can now set access ownership and access controls on a per-container data volume basis. This functionality is integrated into the corporate authorization and authentication system.

The company says the container management system Kubernetes traditionally isn't used in authorization systems such as Active Directory and LDAP. Potentially, an authorized Kubernetes user could access data volume that is not appropriate for their role.

Previously, the company’s PX-Enterprise relied on what the four-year-old company calls "container-granular bring-your-own-key encryption." The company has now added authentication, authorization and ownership as well.

Portworx also added disaster recovery with zero data loss (RPO zero) between data centers in a metropolitan area. This is an advance over today's "single-data-center and multi-availability zone" that is available to Kubernetes deployments. Seamless access to multiple data centers in a metropolitan area significantly strengthens the ability to recover from a data loss incident. The company has also added continuous incremental backups.

Taken together, Portworx Enterprise 2.1 now provides three levels of high availability and data protection for mission-critical apps: within a single data center or multiavailability zones; across data centers or clouds within a metropolitan area; and across data centers spanning the world.
