Hyper-scale, elastic, smart, shared, database aware storage

A method comprising:

• obtaining a bucket number of a storage bucket that can aggregate a database extent in a database file;
• sending, based on the bucket number of the storage bucket, a first request to access the database extent in the database file, wherein the first request contains a location version number;
• detecting that the first request failed because the location version number of the storage bucket is stale;
• and
• in response to said detecting:
• retrieving a latest location version number of the storage bucket, and
• sending a second request that represents the first request except that the second request contains said latest location version number of the storage bucket.

One or more non-transitory computer-readable media storing instructions that, when executed by one or more processors, cause:

• receiving a request to access a database extent in a database file;
• obtaining, based on the request, a bucket number of a storage bucket that can aggregate the database extent in the database file;
• selecting, based on the bucket number of the storage bucket, a storage drive in a storage server;
• accessing, in the storage drive, the database extent in the database file;
• and
• sending a response that is based on said accessing.
