The Disk Pool Manager (DPM) is a storage system for grid sites. It offers a simple way to create a disk-based grid storage element composed by many disk servers.

DPM supports the data and metadata access protocols that are relevant for file management and access in the Grid environment (HTTP, WebDAV, Xrootd, SRM, gridFTP, RFIO).

In the case of flexible protocols like HTTP and Xrootd, it focuses in giving the advanced features that enhance the performance of the analysis applications.

Its focus is on manageability (ease of installation, configuration, low effort of maintenance), while providing all required functionality for a grid storage solution, for example:

  • strong X509 authentication
  • proxy certificates
  • Support for multiple Virtual Organizations
  • support for multiple disk server nodes
  • different space types
  • multiple file replicas in disk pools, ...
