    Abstract: Exemplary methods, apparatuses, and systems receive a first input/output (I/O) trace from a first workload and run the first I/O trace through a cache simulation to determine a first miss ratio curve (MRC) for the first workload. A second I/O trace from the first workload is received and run through the cache simulation to determine a second MRC for the first workload. First and second cache sizes corresponding to a target miss rate for the first workload are determined using the first and second MRCs. A fingerprint of each of the first and I/O traces is generated. The first cache size, the second cache size, or a combination of the first and second cache sizes is selected as a cache size for the first workload based upon a comparison of the first and second fingerprints. A recommended cache size is generated based upon the selected cache size.
