Abstract
A method for determining a primary storage device and a secondary storage device for copies of data comprises determining metrics data for at least two storage devices located on different servers in a computing environment. The method further comprises adjusting the metrics data using a predefined weighting factor for read data blocks rates and a predefined weighting factor for written data blocks rates, where the predefined weighting factor for the written data blocks rates is higher than the predefined weighting factor for the read data blocks rates. The method further comprises selecting a storage device of the at least two storage devices as a primary storage device based, at least in part, on the adjusted metrics data for each of the at least two storage devices.
