Abstract
A cache space management method and apparatus are disclosed. In the method, first, a hit rate of the read cache of the storage system is obtained; and then, a size of the read cache and a size of the metadata cache are adjusted based on the hit rate of the read cache. In the foregoing technical solution, the size of the read cache and the size of the metadata cache are dynamically adjusted by using the hit rate of the read cache as a decision factor. For example, when the hit rate of the read cache is relatively high, the size of the read cache may be increased.
