# Release 21.07-SP1

## Key Enhancements

### VPSA Object Storage

#### Object-Lock S3 API performance improvement

(**ZSTRG-12992,ZSTRG-17467**)

With version 21.07-SP1, Zadara improved significantly its VPSA Object Storage
handling of the following S3 compatible Object-Lock APIs:

- Put-object-retention
- Multi-delete

With Object-Lock enabled use-cases(i.e Veeam’s immutable backup), where the backup
application requires periodical update of the objects in the backend container
(bucket) with an updated “Retention Date”. Updating the object’s metadata
requires a single API request per object, which can result with millions of
consecutive requests. The change in the way the VPSA Object Storage handle
the object metadata allow the Object Storage to serve x3-x4 more requests in
parallel.

#### New account administrator dashboard

(**ZSTRG-18975**)

Similar to the VPSA Object Storage administrator, a new account dashboard
was introduced to provide a snapshot visibility to the account administrators.
The dashboard will provide the following information:

- General VPSA Object Storage information
- Performance metering snapshot:
  - Total throughput
  - Total operations/s
  - Operation type breakdown
  - Capacity history
  - Account status (capacity, containers count, object count, users etc)

Release 21.07-SP1 is a service pack release which includes scalability, security,
usability improvements, new features and bug fixes.

The following section will breakdown the **main** additions and updates to the
Zadara Storage Cloud platform on top of the previous 21.07 major version.
