Description
StorageD is the data aggregator component within archiving systems that supports the work of the Diamond
Light Source (DLS) and the Centre for Environmental Data Analysis (CEDA) at the Rutherford Appleton
Laboratory (RAL). StorageD provides file ingest and recall services to scientists and engineers internationally
through DLS and CEDA. StorageD currently support ingest of over 100TB daily. StorageD uses the CERN
Tape Archive (CTA) backend in writing data to tape. Current holding on tape is approximately 100PB.
Over the past 2 years, StorageD has migrated from using the RFIO access protocol to using XRootD for file
transfer to the backend. This talk will cover the description of the development work on the transition of
StorageD away from RFIO at the backend, towards XRootD. Furthermore, optimisation work that has become
necessary because of this transition will be discussed.
Service management of StorageD includes monitoring, reporting and management with maintenance scripts.
These efforts will be discussed in this talk.
