Abstract
In one embodiment, power level management in accordance with the present description, is provided in a storage unit having both a disk storage drive, and another non-volatile, non-disk memory or storage such as a solid state drive, for storing metadata. The metadata storage provides direct access to the metadata stored in the non-disk storage even though the disk storage drive may be in a low power mode in which the data storage media disk of the disk storage drive is stopped or spinning at a reduced rate of rotation. As a result, power consumption and cooling requirements associated with disk storage drives, may be reduced in a low power level mode of storage unit operation for input/output operations limited to metadata stored in the metadata storage. Other features and aspects may be realized, depending upon the particular application.
