Sommaire
Introduction
- Information only for T2s.
- Information only for DPM for the moment.
- There is still an uncertainty with ATLASGROUPDISK
- Atlas official requirements in http://indico.cern.ch/materialDisplay.py?contribId=1&materialId=slides&confId=37181
- but contents are not final yet.
- There is a technical limitation in DPM. Atlas has contacted DPM developpers to know when proper implementation is available (in September?).
2008
The size is for a typical T2 with ~500 CPU’s

ATLASDATADISK
- Estimation of size comes later
- group associated with the space token: /atlas/Role=production
- namespace to be created: /home/atlas/atlasdatadisk
- namespace acl:
# group: atlas/Role=production user::rwx group::rwx #effective:rwx group:atlas/Role=production:rwx #effective:rwx mask::rwx other::r-x default:user::rwx default:group::rwx default:group:atlas/Role=production:rwx default:mask::rwx default:other::r-x
ATLASMCDISK
- 15TB for a typical T2 with ~500 CPU’s and ~100 TB disk
- 60TB for a T2 requesting for 100% AOD.
- The size may increase in case D1PD comes in this space.
- Namespace ACL:
# group: atlas/Role=production user::rwx group::rwx #effective:r-x group:atlas/Role=production:rwx #effective:rwx mask::rwx other::r-x default:user::rwx default:group::rwx default:group:atlas/Role=production:rwx default:mask::rwx default:other::r-x
ATLASPRODDISK
- 2TB for a typical T2 with ~500 CPU’s (the size is to be re-visited)
- Namespace to be created and its ACL: /atlas/atlasproddisk, write permission only to /atlas/Role=production
# group: atlas/Role=production user::rwx group::rwx #effective:rwx group:atlas/Role=production:rwx #effective:rwx mask::rwx other::r-x default:user::rwx default:group::rwx default:group:atlas/Role=production:rwx default:mask::rwx default:other::r-x
ATLASGROUPDISK
- 6TB for a typical T2 with ~500 CPU’s and ~100 TB disk
- The size may decrease in case D1PD goes into ATLASMCDISK.
- namespaces to be created and their ACLs:
- /atlas/atlasgroupdisk, write permission only to /atlas/Role=production
- /atlas/atlasgroupdisk/phys-exotics, write permission to atlas/Role=production, /atlas/phys-exotics/Role=production
- etc...
ATLASUSERDISK
- 5TB for a typical T2 with ~500 CPU’s and ~100 TB disk
- namespaces to be created and their ACLs: /atlas/user, write permission to all ATLAS users
- dpns-mkdir lcg-se01.icepp.jp:/dpm/icepp.jp/home/atlas/user
- dpns-setacl -m g:atlas:rwx,m:rwx,d:g: lcg-se01.icepp.jp:/dpm/icepp.jp/home/atlas/atlasuserdisk
