Abstract
A method, computer system, and computer program product for managing copies of data objects in a network data processing system. The computer system identifies copies of a data object stored on storage devices. The computer system places the storage devices into groups. Each storage device in a group has a smallest distance from the storage device to a center location for the group as compared to distances to center locations for other groups within the groups. The computer system selects a portion of the copies of the data object for removal from the storage devices based on a management of power for the storage devices such that remaining set of storage devices in each group is capable of handling concurrent requests that have been made historically for the copies of the data object. The computer system removes the portion of the copies of the data object from the storage devices.
