Abstract: A system and method for monitoring the storage estate of an organization using an interactive website that is configured to produce and display a novel set of key performance indicators (KPIs) related to the storage estate, including KPIs related to data collected from at least one of storage area network data and network attached storage data. In one embodiment, the novel set of KPIs includes one or more of protection efficiency, application efficiency, and snapshot overhead, where protection efficiency is calculated as a ratio of logical addressable data storage volume to total physical volume of data storage for storage area network data of the organization, application efficiency is calculated as a fraction of disk storage allocated to end user devices that is actually used by the end user devices for storage area network data, and snapshot overhead is calculated as a ratio of a volume of storage allocated for replicated copies of data to allocated storage for network attached storage data.
