  1. Riccardo Zappi INFN-CNAF StoRM until 2013 and beyond TEG DM & SM, NIKHEF, Amsterdam January 24-25, 2011

  2. Activities January 24-25, 2011, TEG DM & SM, NIKHEF, Amsterdam • Short/Medium term activities: • defined within the EMI context • maintenance and development • Other activities are based on requests and suggestions coming from: • Customers (via EGI and EMI, or directly) • Working groups like TEG

  3. Activities and Improvements (1/3) January 24-25, 2011, TEG DM & SM, NIKHEF, Amsterdam • Robustness: • reactive interventions • bug fixes • user support • proactive activities: • test suites and unit tests • standard adoption • e.g. File System Hierarchy Standard (FHS) compliance • improving product quality

  4. Activities and Improvements (2/3) January 24-25, 2011, TEG DM & SM, NIKHEF, Amsterdam • High Availability, Fault Tolerance • Twin-BE • Service Monitoring • Heartbeat enhancement • Ganglia module • Responsiveness • Synchronous PtG • Performance on SRM call executions

  5. Activities and Improvements (3/3) January 24-25, 2011, TEG DM & SM, NIKHEF, Amsterdam • Security • Argus Integration: • Ban list on DN and VOMS group • Storage Area protection: • Evaluating to use Argus • Space Accounting • StAR (Storage Accounting Record) implementation • Catalogue synchronization mechanism • As defined in EMI

  6. Storage Systems support January 24-25, 2011, TEG DM & SM, NIKHEF, Amsterdam • StoRM relies on underlying file systems • It works with any POSIX FS with ACL and EA enabled • StoRM product is committed to : • support all the wished data access/transfer protocol • http(s), (s)ftp, gsiftp, dav, xrd, torrent, ... • support all the most used, promising and required FS • HDFS, NFSv4.1 • investigate on how to integrate cloud storage solution • AWS-S3, Google CloudStorage

  7. Issues and Solutions to support new SS January 24-25, 2011, TEG DM & SM, NIKHEF, Amsterdam • No ACL support (e.g. AWS-S3, HDFS) • No more Direct Access support (security issue) • Solutions: • No file protocol support: use it as a second tier in ahierarchical configuration (like a MSS) • Adapt StoRM to use only standard permission (minor flexibility) • No EA support • No more default store for checksum values • No more StoRM-system metadata with files • Solutions: • Use of hidden files (like SVN) • short term DB

  8. Supported Protocols January 24-25, 2011, TEG DM & SM, NIKHEF, Amsterdam • File protocol (file:// ) support: • file protocol is supported by design since StoRM was born • to take advantage from Cluster-FS (GPFS and Lustre) • "copy-to-WN" paradigm is used, then other data "access" protocol are (or will be) supported (rfio, xrd) • http e https support: • already supported both in read and write mode • require a SRM interaction (srmPtG and srmPtP with specified http(s) as desired protocol) • gsiftp, rfio and root

  9. Protocols under evaluation January 24-25, 2011, TEG DM & SM, NIKHEF, Amsterdam • WebDAV support • work in progress • It will available in 6-9 months • pNFS support • NFSv4.1 doesn't support EA • Checksum issue • Integration tests are expected : • on dCacheand/or BlueArc(upon availability) • GPFS v3.5: Active File Management (AFM) • Tests are ongoing at CNAF

  10. StoRM sustainability January 24-25, 2011, TEG DM & SM, NIKHEF, Amsterdam • StoRM is currently developed at CNAF • it is highly integrate in Tier-1 storage solution • StoRM is included into the portfolio of middleware products of IGI: • IGI is the Italian NGI (National Grid Initiative) and is part of the European Grid Infrastructure (EGI) • StoRM is developed in the context of EMI, ending in May 2013. Main goals are: • Improve robustness and quality • Harmonization (e.g. Argus integration) • Standard adoption (e.g. http(s), file://, ) • The sustainability is guaranteed by the context
