Status Report Riccardo Zappi INFN-CNAF, Bologna Page CNAF, 2 October 2006

Outline 1. Current Status • Functionalities developed • First SRM v 2. 2 interoperability test results 2. Next steps • Functionalities and Features incoming • Test bed for the experiments • Scenario for T 1 2 T 1 meeting CNAF, 2 October 2006

Migration Status to SRM v 2. 2 of Sto. RM • We started the migration from the released version of Sto. RM implementing SRM 2. 1. 1_modified (begin of July). • The followed strategy is based on adapting the 2. 1. 1 functions already developed. 3 T 1 meeting CNAF, 2 October 2006

SRM v 2. 2 Interoperability test • The interoperability tests are made within GIN context (Coordinated by Alex Sim (LBNL)). • Basic functional tests • Simple scenario for copy • More complex scenario Real time results are visible at: http: //sdm. lbl. gov/srm-tester/v 22 -progress. html 5 T 1 meeting CNAF, 2 October 2006

Next Steps • Basic functionalities (Bo. L, MV, Release. Files) • Documentation for Users and Site Admin – New web site (wiki based) – New install guide (now via YAIM) and config. guide • Some improvements suggested by Vincenzo Vagnoni and risen during the tests. – Multiple volume – Authorization source (group/VO, path) – … • Sto. RM clients (CLI) improvements (man) • . . . 9 T 1 meeting CNAF, 2 October 2006

Timeline expected • Functionalities : mid/end of October • Improvements : mid/end of November • Documentation : ASAP Other tasks are concurrent: - Support GIN inter-op test - Dissemination of Sto. RM - CGW 06 conference (Crakow), Core. Grid meeting (Crakow), SC 06. By the end of October Sto. RM (SRM v 2. 2) will be ready (enough stable) for testing by experiment team, but if there are someone curious the Sto. RM endpoint is srm: //ibm 139. cnaf. infn. it: 8444//srm/managerv 2 10 T 1 meeting CNAF, 2 October 2006

Sto. RM test bed Currently Sto. RM is installed for test purpose only in: -ibm 139. cnaf. infn. it: 8444 - Underlying file system is GPFS v. 3. 1 with 60 GB of space - Dedicated to inter-op test and SC 06 demo. At the begin of November Sto. RM will be able to support more testers, so : - Better test bed should be installed (and different from ibm 139!) - Available to the testing job of experiment. We need the description of how experiment application would like to use the storage. 11 T 1 meeting CNAF, 2 October 2006

Using of SRM v 2. 2 Available by the end of October (declared) • FTS • GFAL • lcg-utils • “Private” clients – Sto. RM provides clients CLI – Other API or Clients are possible 12 T 1 meeting CNAF, 2 October 2006
