The past: research goals andassumptions of last 15 years

• Goal #1: Improve performance

• Goal #2: Improve performance

• Goal #3: Improve cost-performance

• Assumptions

  • Humans are perfect (they don’t make mistakes during installation, wiring, upgrade, maintenance or repair)
  • Software will eventually be bug free (good programmers write bug-free code, debugging works)
  • Hardware MTBF is already very large (~100 years between failures), and will continue to increase
  • Maintenance costs irrelevant vs. Purchase price (maintenance a function of price, so cheaper helps)
