In these times, scientific data intensive applications generate ever-increasing volumes of data that need to be stored, managed, and shared between geographically distributed communities. Datacenters are normally able to provide tens of petabytes of storage space through a large variety of heterogeneous storage and file systems. However, storage systems shared by applications need a common data access mechanism, which allocates storage space dynamically, manages stored content, and automatically remove unused data to avoid clogging data stores. To accommodate these needs, the concept of Storage Resource Managers (SRMs) was devised in the context of a project that involved High Energy Physics (HEP) and Nuclear Physics (NP).
