Overview (I).

• SRB not only used for BaBar.
• Attractive for many projects
• Transparent interface with the Mass Storage
  System (MSS).
• Easy administration of small files to be stored
  into the MSS (container tar ball).
• Interface with some existing relational database.
• OS of your choice on each participating site.
• Collaborative tool in order to share files
• ACLs within groups, domains, zones, metadata,
  annotations.

Overview (II).

• 2 SRB servers ( 1 extra soon)
• SUN NetraT 1405, V440, V480.
• Clients application in a distributed environment
• Lots of time saved in code development.
• Environment with multiple OS
• Linux RedHat, Scientific Linux, Debian.
• Solaris.
• Windows.
• Interfaces
• Scommands invoked from the shell (script based on
  them).
• Java APIs.
• Web interface.

4
SuperNovae Factory (P. Antilogus).

• SRB connected to an other database.
• Telescope data stored into the SRB.
• Collaborative tool (files exchanged between
  users).

Neuroscience research (P. Calvat, G. Bondaz, J-Y
Nief).

• FTP,
• File sharing,

7
Neuroscience research (II).

• Goal make SRB invisible to the end user.
• More than 500,000 files registered.
• Now interfaced within the MATLAB environment
• Data pushed where the CPUs are (CC-IN2P3, ENS
  Lyon).
• 1.5 FTE for 3 months
• Next step
• Ever growing community (a few TBs / year).
• Goal
• Join the BIRN network (US biomedical network).

Summary.

• Lightweight administration for the entire system.
• Fully automated monitoring of the system health.
• Doing user support for each project
  administrator.
• Database
• Information system need to be performant.
• Need to have a DBA.
• Over 140 TB stored in SRB.
• Over 1 million of files for some catalogs very
  soon.
• More projects coming to SRB.
