Storage Workshop July 2007Dr. Doris Ressmann Storage Pools fileserver with 5.2 TB for pools 1 pool 1.7 TB tape connected for all VOs 1 pool 1.7 TB for tape tests (only used by gridka staff) 1 pool 1.7 TB disk-only fileserver with 5.2 TB for pools 1 pools 2.6 TB tape connected (did not come up after update) 1 pool 2.6 TB disk-only 3,2 GHz / 2 GB mem / kernel 64 bit SL4

Storage Workshop July 2007Dr. Doris Ressmann VO support ops, dteam, alice, atlas, cms, lhcb, no dedicated pools for a VO 3 link groups (Test-link, All-tape-link, All-disk-only-link) –psu create link all-tape-link any-protocol all-store world-net –psu set link all-tape-link -readpref=20 -writepref=20 - cachepref=20 -p2ppref=-1 –psu add link all-tape-link tape-pools –psu set linkGroup attribute all-tape-link-group HSM=TSM –psu addto linkGroup all-tape-link-group all-tape-link Is this enough for all SRM 2.2 cases e.g. Custodial, Near line,…Space Manager configuration? all-store covers SRM1.1 directory tags!!!

Storage Workshop July 2007Dr. Doris Ressmann To do gPlazma authentication VOMS –different roles e.g for space reservation more tests of the new tape connection get ATLAS tests going check LHCb requirements…..

Storage Workshop July 2007Dr. Doris Ressmann Info Provider In dCache 1.7 Pool Manager –psu create pgroup ops –psu addto pgroup ops f e_ops GRIIS and dCache SRM on same host infoProviderStaticFile=/opt/lcg/var/gip/ldif/st atic-file-SE.ldif –link to /opt/d-cache/jobs/infoDynamicSE- provider-dcache –Same for plugin In dCache 1.8 a pool belongs to one and only one pgroup !!!!

Storage Workshop July 2007Dr. Doris Ressmann open issues accounting / info system: separation of SE and SRM Is it still possible to have pools shared by different VOs in 1.8? Flavia's DN ( address=....) –without gPlazma its ok, it is used as (E=...) –with gPlazma the requests are with ( address=....)
