Abstract
Various embodiments for managing data by a processor in a multi-tiered computing storage environment. Input/Output (I/O) statistics are examined from each of cache and device drivers in the computing storage environment. Based on the I/O statistics, a ranking mechanism is applied to differentiate data between at least a cache rank and a Solid State Drive (SSD) rank. The ranking mechanism migrates data between the cache rank and SSD rank such that storage space in the cache rank is reserved for those of the plurality of data workload types having a greater adverse effect on a storage performance characteristic if stored in the SSD rank than if those workload types were stored in the cache rank.
