A system for management of a storage system (102, 104) of an organization, comprising: a storage management data repository configured to receive periodic updates from one or more servers or applications (106, 108, 110, 112) coupled to the storage system (102, 104); and a web reporting tool configured to periodically process data from the storage management data repository, the web reporting tool configured to provide one or more reports (130, 132, 134, 136) related to the storage system (102, 104) in a format accessible through a web interface provided to authorized users (122, 124, 126), the one or more reports (130, 132, 134, 136) including a key performance indicator report, called KPI report; wherein the KPI report comprises one of a storage area network key performance indicator report called SAN KPI report and a network attached storage key performance indicator report called NAS KPI report; wherein the SAN KPI report comprises a display of one or more SAN KPIs related to storage area network data called SAN data, of the organization, wherein the NAS KPI report comprises a display of one or more NAS KPIs related to network attached storage, called NAS characterized in that at least one SAN KPI comprises one or more of protection efficiency and application efficiency, protection efficiency being calculated as a ratio of logical addressable data storage volume to total physical volume of data storage for SAN data of the organization, and application efficiency being calculated as a fraction of disk storage allocated to end user devices that is actually used by the end user devices; and in that at least one NAS KPI comprises snapshot overhead calculated as a ratio of a volume of storage allocated for replicated copies of data to allocated storage. a storage management data repository configured to receive periodic updates from one or more servers or applications (106, 108, 110, 112) coupled to the storage system (102, 104); and a web reporting tool configured to periodically process data from the storage management data repository, the web reporting tool configured to provide one or more reports (130, 132, 134, 136) related to the storage system (102, 104) in a format accessible through a web interface provided to authorized users (122, 124, 126), the one or more reports (130, 132, 134, 136) including a key performance indicator report, called KPI report; wherein the KPI report comprises one of a storage area network key performance indicator report called SAN KPI report and a network attached storage key performance indicator report called NAS KPI report; wherein the SAN KPI report comprises a display of one or more SAN KPIs related to storage area network data called SAN data, of the organization, wherein the NAS KPI report comprises a display of one or more NAS KPIs related to network attached storage, called NAS characterized in that at least one SAN KPI comprises one or more of protection efficiency and application efficiency, protection efficiency being calculated as a ratio of logical addressable data storage volume to total physical volume of data storage for SAN data of the organization, and application efficiency being calculated as a fraction of disk storage allocated to end user devices that is actually used by the end user devices; and in that at least one NAS KPI comprises snapshot overhead calculated as a ratio of a volume of storage allocated for replicated copies of data to allocated storage.
