Storage Requirements for CCRC08 for ATLAS

More details can be found in the agenda page of the jamboree meeting.
This is the link to the ATLAS document describing the plans for FDR and CCRC08.
Here is the directory containing the ATLAS documents from Kors Bos (look for the latest "ATLAS-Document-for-FDR-and-CCRC-vXY").
For more details about the ATLAS tokens and their usage, please check this twike page from Kors Bos.
In order for ATLAS to perform tests during the CCRC08 exercise in February 2008 the following requirements should be satisfied by Tier-1s:

  1. Provide the following storage classes:
    • REPLICA-ONLINE (Tape0Disk1)
    • CUSTODIAL-NEARLINE (Tape1Disk0)
    • CUSTODIAL-ONLINE (Tape1Disk1) only for CASTOR@RAL and dCache@FZK
  2. Define the following space token descriptions:
    • ATLASDATATAPE for the CUSTODIAL-NEARLINE storage class to be used for Real data (RAW)
    • ATLASMCTAPE for the CUSTODIAL-NEARLINE storage class to be used for Simulation production activities
    • ATLASDATADISK for the REPLICA-ONLINE storage class to be used for Real data (ESD,AOD,DPD)
    • ATLASMCDISK for the REPLICA-ONLINE storage class to be used for Simulation production activities
    • ATLASDATADISKTAPE for the CUSTODIAL-ONLINE storage class to be used for Real data (REPROCESSING) - this class should be implemented only at some Tier-1 (CASTOR@RAL, dCache@FZK)
    • ATLASMCDISKTAPE or the CUSTODIAL-ONLINE storage class to be used for Simulation production activities - this class should be implemented only at some Tier-1 (CASTOR@RAL, dCache@FZK)

In order for ATLAS to perform tests during the CCRC08 exercise in February 2008 the following requirements should be satisfied by the Tier-0:

  1. Provide the following storage classes:
    • REPLICA-ONLINE (Tape0Disk1)
    • CUSTODIAL-NEARLINE (Tape1Disk0)
    • CUSTODIAL-ONLINE (Tape1Disk1)
  2. Define the following space token descriptions:
    • ATLASDATATAPE for the CUSTODIAL-NEARLINE storage class to be used for Real data (RAW)
    • ATLASDATADISK for the REPLICA-ONLINE storage class to be used for Real data (ESD,AOD,DPD)
    • ATLASMCDISKTAPE or the CUSTODIAL-ONLINE storage class to be used for Simulation production activities

In order for ATLAS to perform tests during the CCRC08 exercise in February 2008 the following requirements should be satisfied by Tier-2s:

  1. Provide the following storage classes:
    • REPLICA-ONLINE (Tape0Disk1)
  2. Define the following space token descriptions:
    • ATLASDATADISK for the REPLICA-ONLINE storage class to be used for Real data (ESD,AOD,DPD)
    • ATLASMCDISK for the REPLICA-ONLINE storage class to be used for Simulation production activities

Furthermore, the following requirements must be satisfied:

  1. Make available an ATLAS specific path (ex. /atlas) for tape and disk. ATLAS will then create further paths specifying the desired space token, provided that tokens will be decided somewhere in some top levels and will not change for data stored in the leaves of that top directory.
  2. Enable the following group/roles to write into the spaces above. Please make sure that users with the role described below can write and remove files created by other users with the same role:
    • /atlas/Role=production
    • /atlas/soft-valid/Role=production
  3. Publish in the GLUE schema the ATLAS tokens and path in the GlueVOInfo objects
  4. Publish the size of the Storage Area correspondent to a specific Storage Class both total and available.

For publishing information in the GLUE schema, you can find an example here.
