System providing storage as a service

摘要

A computer-implemented method for providing stor­age resources (R01-R09) of a storage management system (201), the method comprising: receiving (101) a storage service request comprising an indication of a service class (301-303); determining (102) all resource managers (RM1-RM5) mapped to the in­dicated service class according to a first mapping (212) each resource manager having a generic API; for each of the determined resource managers, determine (104) se­lected ones of all the storage resources controllable by said re­source manager; gathering (105) monitoring data of the selected storage resources; comparing (106) the gathered monitoring data for calculating a score for each one of the selected storage resources; and calling (107) at least one function of the resource manager operable to control the storage resource having an optimum score.
