Bank Saves Millions by Optimizing Mainframe Capacity with CPT Global

Challenge 

A major global bank needed to increase their mainframe system capacity while adhering to a tight IT budget. Another vendor proposed a hardware upgrade of 750 MIPS, far exceeding the bank's actual requirements. 

CPT Global’s Actions 

• Conducted a thorough analysis of z16 capacity options, leveraging two years of previous mainframe optimization work with the bank. 

• Identified that prior MIPS reductions and WLM configuration changes negated the need for a larger upgrade. 

• Recommended reducing the hardware proposal by two CPUs to meet capacity needs cost-effectively. 

Results 

• $1.5 million saved annually in software costs. 

• $140,000 saved per mainframe by avoiding unnecessary zIIPs. 

• Maintained workload stability while preparing for a seamless 2024 workload refresh. 

By working with CPT Global, the bank avoided costly hardware upgrades, saving millions while meeting their capacity requirements.
