SQL 2016 - NU/NC Index Missing From sys.partitions

Question

Is there a reason that a non-unique, non-clustered index would have 0 corresponding records in the sys.partitions view? There is a CI on the same table and there is a record for it in the view. My understanding is that any NCI should have at least one record in sys.partitions. Thanks.

Answer 1

A disabled index has no storage.
