Abstract
A data storage device includes a cache for a data storage and a processor. The data storage includes an object storage. The processor obtains cache hardware heuristics data for a first time period; makes a first determination that the cache hardware heuristics data for the first time period does not meet a goal associated with the first time period; and populates the cache using a reduced size index cache in response to the first determination during a second time period.
