Distribution of quantities of an increased workload portion into buckets representing operations

A computing system comprising:

• a processor;
• and
• a non-transitory storage medium storing instructions executable on the processor to:
• receive an indication of an increased workload portion to be added to a workload of a storage system, the workload represented by a representation of buckets representing input/output (I/O) operations of different characteristics;
• compute, based on quantities of I/O operations of the different characteristics in the workload, factor values that indicate distribution of quantities of I/O operations of the increased workload portion to the buckets representing I/O operations of the different characteristics;
• distribute, according to the factor values, the quantities of the I/O operations of the increased workload portion into the buckets representing I/O operations of the different characteristics;
• and
• generate a modified representation of buckets representing I/O operations of different characteristics in a modified workload that includes the workload and the increased workload portion.

A method performed by a system comprising a hardware processor, comprising:

• receiving an indication of an increased workload portion to be added to a workload of a storage system, the workload comprising buckets representing operations of different input/output (I/O) sizes;
• compute, based on quantities of operations of the different I/O sizes in the workload, factor values that indicate distribution of quantities of operations of the increased workload portion to the buckets representing operations of the different I/O sizes;
• distribute, according to the factor values, the quantities of the operations of the increased workload portion into the buckets representing operations of the different I/O sizes, to form modified buckets representing operations of the different I/O sizes;
• and
• predict a performance of the storage system based on the modified buckets representing operations of the different I/O sizes.
