Summary

• AMS is capable of high performance

  • Ultimate performance limited by disk speeds
    • Should be able to deliver average of 20 MB/Sec per disk

• The oofs interface + other protocols greatly enhance performance, scalability, usability, and security

• 5+TB of SLAC data has been processed using AMS+HPSS

  • Some AMS problems
  • No HPSS problems

• SLAC will be using this combination to store physics data

  • BaBar experiment will produce over a 2 PB database in 10 years
    • 2,000,000,000,000,000 = 2´1015 bytes @ 200,000 3590 Tapes
