  1. Tivoli Storage Manager at CERN David Asbury CERN/IT/FIO HEPIX, Rome, 6 April 2006

  2. Reasons for backup • Accidental corruption of files/mail/dbs • Storage failure, disks, raid arrays(!) • Need to get a server running again • Fire, water, power, cooling problems • Backup is very boring until ….! HEPIX Rome 2006: TSM at CERN

  3. AFS volume backup -> Castor TSM TSM TSM TSM Castor CERN Policy on Data • Home Directories • AFS • Windows DFS • Mail • Microsoft Exchange • Databases • Unix group & project servers • Experimental Data Only Servers HEPIX Rome 2006: TSM at CERN

  4. Why use TSM? • Good experience over 15 years • Backup & Archive available • Collocation supported (so restores are faster) • Multiple copies in different locations • Very tuneable and scales to a large service • TDP available with RMAN for dbs (incremental) • Good monitoring software – Servergraph • Cost saving from using single product (stop Legato) HEPIX Rome 2006: TSM at CERN

  5. TSM server1 TSM server2 Terminology TSM machine RAID disks DFS Server FC switch Client nodes Tape drives Gbit HEPIX Rome 2006: TSM at CERN

  6. Service Revived in 2003 • 2 x old IBM F50 machines • Added modern IBM p630 machine in 2003 • FC switch to attach disks & tapes • Infortrend disk RAID arrays • Added IBM p5-550 machine (in another building), connected by FC HEPIX Rome 2006: TSM at CERN

  7. New Machine hardware • IBM p5-550, AIX 5 • 2 x cpus 1.6 GHz • 8GB memory • 2 fiber-channel HBAs (disk, tape) • 2 Gigabit interfaces • Brocade 3800 fiber-channel switch 16-port • 2 Infortrend SATA disk RAID trays • 5.5TB usable RAID5 staging space • 1 Infortrend FC disk tray (for TSM dbs) • 5 STK 9940B tape drives (200GB) HEPIX Rome 2006: TSM at CERN

  9. Growth! HEPIX Rome 2006: TSM at CERN

  10. Monitoring Software • Servergraph/TSM • Monitors all licensed TSM servers • Mature product, understands TSM well • Web interface - extendable • Email warnings • To users about failed backups • To admin about server and hardware problems • Capacity Planning HEPIX Rome 2006: TSM at CERN

  11. TSM on a Linux machine • Reduce capital costs • Easier to prevent scalability problems • Being tested in CERN • Recent version supports STK ACSLS HEPIX Rome 2006: TSM at CERN

  12. TDP for ORACLE • Tivoli Data Protection for Oracle • Allows incremental backups with RMAN • Important for future Physics meta-dbs • ~60 databases in CERN now HEPIX Rome 2006: TSM at CERN

  13. LANless Backups • Client to TSM tape via fiber-channel • Avoids TCP/IP overhead in client & server • Avoids bottlenecks in LAN • Needs available tape drives (as before) • Still need staging space for REDO logs • High rate of metadata from LHC HEPIX Rome 2006: TSM at CERN

  14. LANless Backup TSM ORACLE Gbitx2 Gbit x 2 TSM server ORACLE TSM client DB TSM Storage Agent FC-16 switch FC-16 switch HEPIX Rome 2006: TSM at CERN
