Release 20.12¶

Release 20.12 is an enhancement to previous release 20.01 with some scalability, security, and usability improvements, new features and fixes to issues that were found in previous releases. This zStorage release has many key enhancements that continue to round out the Zadara zStorage enterprise grade feature set!

Zadara Kubernetes Operator¶

Containers are an emerging method for running applications. Adoption of Kubernetes (and containers usage in general) is growing in the enterprise. Container based applications require persistent storage that Zadara VPSA provides.

The Zadara Operator provides storage and data management for K8s stateful applications as a cloud-native service, while leveraging Zadara’s enterprise grade Storage-as-a-Service VPSA for provisioning and managing persistent storage.

Zadara Operator provides:

Zadara CSI driver automatic installation and management Automatic K8s application discovery.
Application protection using an intelligent and efficient snapshots mechanism.
Custom snapshots scheduling for application protection.
Instant application clone.
CLI for centralized management for Zadara’s K8s assets.
Migrate application from one cluster to another.

More information can be found at the Zadara Operator Github repository.

IPv6¶

Zadara storage now fully supports IPv6 for both hosts connectivity and management purposes.

Security¶

TLSv1.1 protocol was disabled for all Zadara Web Applications, TLSv1.2 and TLSv1.3 are the supported TLS protocols.

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

Auto Tiering¶

With the VPSA Flash Array, customers can now have primary storage pools consisting of both flash (SSD) and hard disk drives (HDD) or flash (SSD) and object storage (Zadara or other S3 compatible object storage). With these new hybrid primary storage zStorage Flash Array deployments, data is automatically placed on the higher performing flash drives if frequent access is needed, and the less frequently accessed data is placed on the lower cost hard disks/object storage .

The business value of Auto Tiering lies in the fact that it enables efficient use of the underlying storage media/resources.

Max Volume Size increase¶

With the 20.12 release, the maximum capacity supported per a VPSA (and a single volume allocated on it) increases from 200TB / 250TB to 500TB in VPSA Storage Array, and VPSA Flash Array. This will be very appealing to customers using large file systems for backup repositories, media repositories and/or large file archives.

File Analytics¶

This release introduces the new built in file analytics capabilities for VPSA NAS shares. Zadara File Analytics helps customers navigate through data and gives them better visibility to manage their data more effectively. File Analytics helps solve data challenges around ownership, storage consumption, storage optimization, and data protection. It also reports on key growth trends and capacity utilization trends

File Access Audit¶

THis release keeps full access log per file system. Users can now have access to a secure log of any file operation (read/write/rename/etc… for auditing purposes.

File History¶

This release adds File History capabilities to NFS shares, as it is supported for SMB shares. File History allows quick restore of any specific version of a given file.
