MIGRATION POLICY ADJUSTMENT METHOD, CAPACITY-CHANGE SUGGESTION METHOD AND DEVICE

摘要

A migration policy adjustment method, capacity-change suggestion method and device. The migration policy adjustment method comprises: calculating capacity information of a first storage resource pool of a data storage server cluster within a preset time, wherein, the first storage resource pool is configured to store a data partition having an access popularity value exceeding a preset access popularity value threshold (S102); determining, according to the capacity information, whether a storage capacity of the first storage resource pool has changed (S104); adjusting a migration policy of the data partition of the data storage server cluster when it is determined that the storage capacity has changed (S106). The above solution addresses a problem in the prior art in which a high-performance storage medium is wasted and service accessibility is reduced because of a static manually-configured configuration.
