Abstract
Techniques for managing disks involve: determining a current usage parameter associated with each of a plurality of disk sets, the current usage parameter indicating usage associated with a capability of each of the plurality of disk sets, and the capability comprising at least one of the following: a number of permitted accesses per time unit and a number of permitted writes per time unit; imbalance degree associated with the plurality of disk sets, the first imbalance degree indicating a difference in the current usage parameters of the plurality of disk sets; and causing data in at least one disk slice of a first disk set to be moved to a second disk set of the plurality of disk sets, so as to lower down the first imbalance degree. In this way, a better balance can be achieved among performances of respective disks after adjustment.
