DRM Deployment Readiness Plan Alex Sim Scientific Data Management Group Computational Research Division Lawrence Berkeley National Laboratory
Goals Deploy Disk Resource Manager (DRM) on to a standard OSG-SE/CE What is DRM? an SRM implementation on a disk-based unix file system Compliant to SRM spec v1.1 Simple packaging and easy deployment A version for SRM spec v2.2 Coming soon
Purpose Provide managed access to tactical storage on execution sites Provide access to storage through the SRM interface by putting an SRM onto the manageable disk space Create web presence through jClarens and/or GridCAT
STAR analysis scenario works Current Status STAR analysis scenario works an app runs jobs that bring files from a remote site, create result files and move the files to the remote archival site DRM packages are distributed through VDT and the web (http://sdm.lbl.gov/srm-dist) Deployed and operated with simple administrative steps About 16 sites including a few ATLAS Tier2 sites and other Grids
Test/Verify DRM services SRM-Tester is available through VDT as separate packages Works with any SRMs for compatibility and interoperability testing Test results are available on the web http://sdm.lbl.gov/srm-tester
Plans Determine and update any necessary changes in the current distribution package (DRM v1.2.12) Support for DRM service deployments and usage More application usage to repeat the deployment and test Deployment of DRM for SRM v2.2
