1 Data & Storage Services CERN IT Department CH-1211 Genève 23 Switzerland t DSS CASTOR Status Alberto Pace

2 CERN IT Department CH-1211 Genève 23 Switzerland t Internet Services DSS Castor evolution in two years Since 2008 –40 minor releases: https://savannah.cern.ch/files/?group=castor https://savannah.cern.ch/files/?group=castor –Released 2.1.7, (repack, xroot), (new test suite, syslog) Effort focused on reducing operational cost and architecture simplifications

3 CERN IT Department CH-1211 Genève 23 Switzerland t Internet Services DSS Today Data Storage Services Castor very stable –All efforts focussed on further consolidation –New monitoring with detailed indicators for both stager and SRM performances SRM v2.9 released –Addresses the SRM instabilities reported during the December LHC run –Includes also improved monitoring 150 M files 23 PB of data 1300 nodes hard disks tapes

4 CERN IT Department CH-1211 Genève 23 Switzerland t Internet Services DSS Outlook for the future Several years of stable operation on the horizon –Return of investment is coming –Focus development effort on further consolidation In particular, improve Castor interfaces for physics analysis –Xroot and direct file system access –Integration with ROOT clients for analysis –Integration with native xroot instances offering low latency read/write storage for analysis
