Grid Storage

WLCG moves and stores hundreds of petabytes of data - much of it is replicated, to ensure availability and resilience. GridPP provides storage in WLCG via the Tier 1 at RAL and via its Tier 2 sites. The grid storage is based on the so-called "storage elements" (or SEs), which provide a grid interface to quite diverse storage systems. SEs include control interfaces like SRM, information interfaces based on LDAP, and interfaces for data transfer and access.

GridPP includes a Storage and Data Management group, a group of which provides support for the SEs, data transfer protocols, performance and resilience. And interoperation. And is generally the fount of all knowledge, at least as regards grid storage and its use.
