WLCG Archival Storage Group


The group has been formed to tackle two main themes

  • establish a knowledge-sharing community for those operating archival storage for WLCG
  • understand how to monitor usage of archival systems and optimise their exploitation by experiments

Main point of contact for all involved parties is mailing list.

For low level tape technology related discussion there is also mailing list.
