# Release 20.12-SP2 ## Key Enhancements ### New management graphical interface We’re excited to announce the availability of our revised VPSA graphical user interface. The dashboard was redesigned to provide a snapshot to the VPSA Storage Array/Flash-Array/Object Storage state: - Current workload - Capacity utilization and trend - Resources status ### VPSA Storage Array #### Support Azure BLOB as an Object Storage tier Azure BLOB can be used in the VPSA Flash-Array as an Object Storage Tier. #### Support replacement of KMIP KMS key UUID used in the VPSA KMS keys that were rotated can now be replaced with a new key in the VPSA management interface. ### VPSA Object Storage #### Container level replication Container level replication allows an asynchronously object replication between Zadara’s VPSA Object Storage to a remote VPSA Object Storage or other S3 compatible Object Storage. Zadara’s container level replication unblocks a new set of replication scenarios: - Move the data closer - Container replication can reduce latency for read operations by allowing the data the be consumed from the closest proximity. - Distribution - post processing, the data can be shifted to additional locations. - Optimizing cost - replicating the data to a remote location that uses a cheaper protection policy. - Data redundancy - you can maintain an additional copy of your data in an additional location (VPSA Object Storage, AWS S3 or any other s3 compatible storage) The container level replication feature will be ready to use on any Zadara VPSA Object Storage that is running version 20.12-SP2 or later. Configuring replication job may incur additional charges for data transfer, please contact your cloud administrator for additional information. ### Interoperability #### CSI Driver Zadara’s VPSA Kubernetes CSI driver updated - Version 1.3.6 is now publicly available. The full list of changes is available in the [CSI 1.3.6](#changelog-csi) section of the release notes. The latest driver installation and usage information can be found at [Zadara’s CSI Github repository](https://github.com/zadarastorage/zadara-csi/tree/release-v1.3.6) Release 20.12-SP2 is a service pack release to the previous Zadara 20.12-SP1 release which includes scalability, security, usability improvements, new features and bug fixes.
