2. Enabling Grids for E-sciencE INFSO-RI-508833 2 What is SRM? Storage Resource Manager is a middleware component that provides a common iterface to different Mass Storage System or simple disk caches on a Grid. The SRM does not perform any file transfer itself,but can invoke middleware components that perform file transfers, such as GridFTP.
