Organizations are exploiting the fundamental
strengths of the mainframe today
• Transaction Processing
• Data Serving
• Mixed Workloads
• Operational Efficiency
• Trusted and Secure Computing
• Reliable, Available, Resilient
• Virtually Limitless Scale
Compelling economics:
68 for 6
Mainframes account
for 68% of production
workloads, but only 6%
of IT spend
