Translations

VPSA GUI and Provisioning Portal are now fully translated to the following languages: English, German, Japanese, Korean and Portuguese.


IPv6

Zadara storage now support IPv6 for hosts connectivity.


SNMP Traps

Customers running their own private clouds and want to get alerts to their SNMP manager can now configure it. Both VPSA and Storage Nodes alerts are sent as SNMP traps. Supports both SNMP V2 and V3.


What’s new in VPSA Storage Array and All Flash Array


Backup to Object Storage

The VPSA built-in backup facility can use AWS S3 Object Storage different classes to optimize the usage of S3 capacity. It supports S3 Standard, S3 Standard Infrequent Access, and S3 Intelligent Tiring.


Interoperability

CSI Driver

Zadara now supports Persistant Kubernetes Container Storage Interface (CSI). CSI is a standard for exposing arbitrary block storage to containerized workloads on Container Orchestration Systems (COS) like Kubernetes. This gives Kubernetes users the ability to use Zadara block and file volumes as persitent storage for containers and makes the system more secure and reliable.

The VPSA Storage Array CSI Driver is publicly available at the Zadara CSI Github repository.
