Selectively limiting throughput of test objects that share system resources with production objects

A data storage system, comprising control circuitry that includes a set of processing units coupled to memory, the control circuitry constructed and arranged to:

• receive a set of I/O requests directed to (i) a production data object stored in the data storage system and (ii) a set of test versions of the production data object, each of the set of test versions stored in the data storage system;
• identify, from among the set of received I/O requests, I/O requests directed to the set of test versions of the production data object;
• and
• selectively throttle a throughput of the identified I/O requests directed to the test versions relative to a throughput of I/O requests directed to the production data object.

A computer program product including a set of non-transitory, computer-readable media having instructions which, when executed by control circuitry of a data storage system, cause the control circuitry to perform a method for managing I/O (input/output) requests, the method comprising:

• receiving a set of I/O requests directed to (i) a production data object stored in the data storage system and (ii) a set of test versions of the production data object, each of the set of test versions stored in the data storage system;
• identifying, from among the set of received I/O requests, I/O requests directed to the set of test versions of the production data object;
• and
• selectively throttling a throughput of the identified I/O requests directed to the test versions relative to a throughput of I/O requests directed to the production data object.
