HypeScale SQL DB, when will the "allocated" disk space auto increase? - Used space 10.07 TB Allocated space 10.1 TB

Question

On my HypeScale SQL DB, when will the "allocated" disk space auto increase?

currently Used space is 10.07 TB

and Allocated space is 10.1 TB

For Azure SQL Database Hyperscale, you do not manually increase the disk size from 10 TB to 11 TB.

Hyperscale storage grows automatically as data is added, up to 128 TB for a single database.  

Answer 1

You do not need to wait for or configure a jump from 10 TB to 11 TB. In Azure SQL Database Hyperscale, storage is allocated automatically as writes consume the remaining free space. Each data file grows in 10-GB increments, and multiple files can grow at the same time, so the allocated value may rise by one or several 10-GB chunks rather than a whole terabyte.

With 10.07 TB used and 10.1 TB allocated, the database still has roughly 0.03 TB of allocated-but-unused space. When additional inserts or index operations require more space, Hyperscale should allocate more automatically. Portal and Azure Monitor values can also lag briefly, so check the allocated_data_storage and storage metrics, or sys.database_files, if you need a precise view.

For a standalone Hyperscale database, growth is supported up to 128 TB. No manual file-size change is required.
