TAPE Testbed

• Available tape endpoints: INFN-T1 (StoRM), BNL (dCache 6.2)
• All disk storage implementation (dCache, DPM, Echo, EOS, StoRM, XRootD)
• Rucio DOMA RSE name: TAPE_"site"_"implementation"_{TAPE,DISK}

FTS (fts3-devel)

• necessary config updates
• TURL_3RD_PARTY_PROTOCOLS=https;gsiftp;root
  • this will come together with new gfal that use integrated SciTokens "library"
  • right now it is possible to use fts3-devel-next which is already configured

TESTS

• Functional Test TAPE
  • every hour transfer 1GB file from / to each site (rule removed after 4 days)
  • basic transfer monitoring in Kibana
  • full debug info in fts3-devel logs (direct link from Kibana page)
  • (currently doesn't work for tapes - require FTS configuration update)
• What kind of tests we would like to see to be confident for switching production instances to SRM+HTTP?
• Do we want to include fraction or all ATLAS & CMS TAPE endpoints?
  • Fraction is sufficient to be sure Rucio -> FTS -> gfal -> SRM+HTTP chain works
  • Quite a lot of communication would be necessary to include all TAPEs
