Abstract: The present subject matter relates to managing a storage pool. In one example, the present subject matter includes identifying, from amongst a plurality of volumes, meta-data service class volumes and data service class volumes based on attributes of volumes. The present subject matter further includes storing a plurality of objects amongst volumes, such that meta-data of objects is stored on meta-data service class volumes and data of objects is stored on data service class volumes, where each object is one of a frequently accessed object and infrequently accessed object. Further, the present subject matter includes determining at least one data storage device, from amongst data storage devices having data service class volumes, such that the data service class volumes store data of infrequently accessed objects, from amongst the objects, and maintaining the at least one data storage device having the data service class volumes in a low power mode.
