Analysis

  • Sub-5,000 MIPS
  • 5,000 to 20,000 MIPS
  • Over 20,000 MIPS

Impacts and Recommendations

  • The growth in reliability and capacity of distributed Linux and Microsoft Windows environments will drive sub-500 MIPS IBM mainframe customers to leave the platform
  • The acceptance of lower-cost commodity hardware for mission-critical workloads will cause IBM mainframe customers to struggle to justify the value proposition of this flagship IBM platform in the sub-1,000 MIPS market segment
  • Differences in ROI models and increased complexity of larger mainframe workloads are causing 1,000 MIPS to sub-2,000 MIPS IBM mainframe customers to more gradually migrate to Linux or Microsoft Windows environments
  • Conclusion
