Smart data placement

A non-transitory computer-readable storage medium storing executable computer instructions that, when executed by one or more processors, cause the one or more processors to perform operations comprising:

• obtaining respective performance signals associated with respective hard disk drives of a collection of hard disk drives, the collection of hard disk drives comprising a plurality of hard disk drives that are dedicated to activities of a service;
• determining a collection failure prediction for the collection of hard disk drives by, for each respective hard disk drive of the collection of hard disk drives, determining a hard disk drive failure prediction by:
• inputting the respective performance signals into a supervised machine learning model;
• and
• receiving as output from the supervised machine learning model the hard disk drive failure prediction for the respective hard disk drive;
• determining, based on the received outputs, that the collection failure prediction is associated with a migration condition;
• and
• responsive to determining that the collection failure prediction is associated with the migration condition, causing a migration of data from the collection of hard disk drives to a second collection of hard disk drives.

A system comprising:

• memory with instructions encoded thereon;
• and
• one or more processors that, when executing the instructions, are caused to perform operations comprising:
• obtaining respective performance signals associated with respective hard disk drives of a collection of hard disk drives, the collection of hard disk drives comprising a plurality of hard disk drives that are dedicated to activities of a service;
• determining a collection failure prediction for the collection of hard disk drives by, for each respective hard disk drive of the collection of hard disk drives, determining a hard disk drive failure prediction by:
• inputting the respective performance signals into a supervised machine learning model;
• receiving as output from the supervised machine learning model the hard disk drive failure prediction for the respective hard disk drive;
• determining, based on the received outputs, that the collection failure prediction is associated with a migration condition;
• and
• responsive to determining that the collection failure prediction is associated with the migration condition, causing a migration of data from the collection of hard disk drives to a second collection of hard disk drives.
