Mainframes are complex but reliable and fast processing platforms. Their usage outlays constitute a significant proportion of an organisation's IT budget as costs incurred can sometimes be high. Furthermore, according to experts, organisations should expect a 15 to 20% annual increase in CPU resource consumption. Reducing the costs of a company's mainframe environment while minimising risk is therefore a key challenge facing every organisation's IT department. For this Spanish retail bank, GFT improved IT resource consumption and performance by a total of 7966 minutes per month.
The challenge
Mainframe optimisation to support three times higher operational volumes
- Following the acquisition of various banks, optimisation of mainframe resources was required to manage 3 times higher operational volumes with just twice the z/OS power
- Identify performance patterns and propose actions to make improvements
- Analyse batch scheduling and propose improvements
The engagement
Mainframe usage review and improvement advice
- 11 month engagement with up to 5 people working simultaneously on different applicationssimultaneously for different applications
- 40+ patterns documented
- 1,000+ improvements proposed
The benefit
Improved consumption of IT resources and enhanced performance
- Reduction in overall MIPS and cost maintenance
- Average savings in elapsed time: 7966 min/month
- Average savings in CPU time: 750 min/month
