Data movement based on write penalties of input/output patterns associated with storage objects

A computer program product comprising a non-transitory processor-readable storage medium having stored therein program code of one or more software programs, wherein the program code when executed by at least one processing device causes the at least one processing device to perform steps of:

• determining, based at least in part on monitoring input/output operations for a given storage object for a designated period of time, an input/output activity level and a given input/output pattern of the given storage object for the designated period of time, the given storage object being stored utilizing a first type of storage resources associated with a first one of two or more storage tiers in a storage system;
• determining a write penalty of the given input/output pattern, the write penalty of the given input/output pattern being associated with writing storage objects having the given input/output pattern to at least a second type of storage resources associated with a second one of the two or more storage tiers in the storage system;
• determining a predicted performance difference of the storage system which would result from movement of the given storage object from being stored utilizing the second type of storage resources associated with the second one of the two or more storage tiers;
• determining, based at least in part on the input/output activity level of the given storage object, the write penalty of the given input/output pattern, the predicted performance difference and a designated write penalty offset threshold, whether to move the given storage object from being stored utilizing the first type of storage resources associated with the first one of the two or more storage tiers in the storage system to being stored utilizing the second type of storage resources associated with the second one of the two or more storage tiers in the storage system;
• and
• moving, responsive to an affirmative movement determination, the given storage object to the second type of storage resources associated with the second one of the two or more storage tiers in the storage system.

A method comprising:

• determining, based at least in part on monitoring input/output operations for a given storage object for a designated period of time, an input/output activity level and a given input/output pattern of the given storage object for the designated period of time, the given storage object being stored utilizing a first type of storage resources associated with a first one of two or more storage tiers in a storage system;
• determining a write penalty of the given input/output pattern, the write penalty of the given input/output pattern being associated with writing storage objects having the given input/output pattern to at least a second type of storage resources associated with a second one of the two or more storage tiers in the storage system;
• determining a predicted performance difference of the storage system which would result from movement of the given storage object from being stored utilizing the second type of storage resources associated with the second one of the two or more storage tiers;
• determining, based at least in part on the input/output activity level of the given storage object, the write penalty of the given input/output pattern, the predicted performance difference and a designated write penalty offset threshold, whether to move the given storage object from being stored utilizing the first type of storage resources associated with the first one of the two or more storage tiers in the storage system to being stored utilizing the second type of storage resources associated with the second one of the two or more storage tiers in the storage system;
• and
• moving, responsive to an affirmative movement determination, the given storage object to the second type of storage resources associated with the second one of the two or more storage tiers in the storage system;
• wherein the method is performed by at least one processing device comprising a processor coupled to a memory.
