The IBM Mainframe has been the computing workhorse for many large organizations. According to Gartner, there are approximately about 14 million MIPS (million instructions per second) installed globally*. They run complex, mission critical applications and are known to be secure, efficient, reliable and scalable. However, they can be expensive to maintain and are known to have high software licensing costs. The software licensing cost calculations are mostly dependent on MIPS installed or consumed on the mainframe.
In the current economic scenario, IT budgets are constantly under pressure and there is an expectation to do more with less. Most organizations also face a challenge of increasing data volumes to keep up with the ever increasing demand for more information and thereby the need for more processing power. Large organizations have realized that they can reduce their Total Cost of Ownership (TCO) by tuning workloads running on the Mainframe. They have also realized that their TCO can be significantly reduced by implementing various enhancements that have arrived with new releases of IBM mainframe software.
HCL uses its proprietary framework for Workload Optimization to help customers analyze their workloads and identify opportunities for performance tuning. This framework takes into account the Environment, System & Subsystem parameters, usage & runtime data from SMF, data from Performance Tools, History Reports and Application Architecture to arrive at an optimal solution.
HCL offers the following solutions to optimize the workloads running on the mainframe:
Environment, System & Subsystem Tuning
Data Access & Code Tuning
Application Architecture & Design Optimization
We offer the following benefits to customers:
