There is provided a distributed storage system (DSS) and method of operating thereof. DSS comprises Objective Based Configuration Module (OBCM) operatively coupled to a plurality of interconnected computer nodes. Computer nodes comprise processing resources to calculate data indicative of conformity between 1) parameters relating to storage-related resources connected to respective interconnected computer nodes and at least partially allocated to a logical storage entity and 2) a Service Level Specification (SLS) indicative of user-defined storage requirements referring to the logical storage entity, and to inform the OBCM accordingly. OBCM is configured to: use the conformity indicative data to assess conformity status (over-utilized, normal or under- utilized) for a storage location with respect to storage-related resources placed thereon; calculate a reconfiguration for the DSS so that to re-allocate storage-related resources from storage location with under-utilized status to a storage location with over-utilized status; and perform measures for re-allocating according to the calculated reconfiguration. |
