Paper reading 6:

Read "A Case for Redundant Arrays of Inexpensive Disks (RAID)" by David Patterson, Garth Gibson and Randy Katz.

Comment on the following:

  • What was the main motivation for RAID in this paper?
  • Did prediction of processor performance and disk capacity hold?
  • In the proposed designs of RAID 1 to RAID 5, how was performance and capacity balanced?
  • What were some of the open issues? Which were significant?
  • In retrospect, what do you think were important contributions? What did the authors get wrong?
