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.

Abstract: Example methods and apparatus for managing a storage system are described. The storage system includes a plurality of control nodes. One example method includes receiving a first operation request of a client by a first control node in the plurality of control nodes. The first control node creates a first object on a first storage node based on the first operation request.
