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.
