Methods, apparatus, and processor-readable storage media for automatically determining sizing configurations for storage components using machine learning techniques are provided herein. An example computer-implemented method includes obtaining multiple items of input related to at least one storage component; determining a set of storage component sizing configurations by processing at least a portion of the multiple items of input using a first set of one or more machine learning techniques comprising at least one deep learning technique; identifying a subset of the storage component sizing configurations by processing at least a portion of the determined set of storage component sizing configurations using a second set of one or more machine learning techniques; and performing one or more automated actions based at least in part on the identified subset of storage component sizing configurations.
