A VSP or virtual storage portal refers to a web application allowing users and businesses to edit, manage and view storage that is rented from any cloud storage provider. Using the VSP users can handle and even forecast storage resources with the help of the existing storage infrastructure. So, the virtual storage portal is a kind of Internet-based control panel for storage which can be accessed via an Internet browser interface. It is provided by the cloud storage provider and allows clients to add or delete storage space and forecast storage needs for the future. This forecasting is based upon usage patterns and the VSP allows administrators to monitor performance of the storage set-ups.
