|Here’s where SDSC
expertise comes in and pulls the pieces together.
|Data Grid Technology
|The preservation of
CwH content is based on using data grid technology to manage distributed
data. The Storage Resource Broker
(SRB) is used as the preservation repository.
A central metadata catalog (MCAT) manages preservation metadata for
each video file. A dedicated MCAT
instance called UCTVStudioArchive was set up.
Two additional logical storage resources were registered to store
digital video replicas on SAMQfs (uctv-fs1) and HPSS (hpss-sdsc). Also, SRB client software and Kepler
scientific workflow software were installed on the eMac machine at UCTV. Finally, a grid brick (srbbrick7) with
300GB of disk space was configured for the DIGARCH project.
