2. 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

3. 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

4. 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 (
Deployed and operated with simple administrative steps
About 16 sites including a few ATLAS Tier2 sites and other Grids

5. 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

6. 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
