MLC costs already consume the largest chunk of many sites mainframe budgets. Here's how you can beat the MLC price increase.
Which Workloads Should I Migrate to the Cloud?
The cloud provides an economic model for computing that may work well for some workloads by reducing costs and having end users pay for what they use.
5 Reasons Why All-Flash Arrays Won’t Magically Solve All Your Problems
It may feel like all-flash systems will solve all your performance issues, but the complexity of the entire infrastructure ensures that there are still plenty of problems to run into.
Mainframe Capacity “Through the Looking Glass”
When processor cache is optimized, mainframe processors remain productive by actively executing instructions rather than unproductively burning cycles.
Achieving Significant Software Cost Reduction on the IBM z13
Software cost optimization initiatives such as lowering RNI help reduce both MIPS and the cost of IBM Monthly Licensing Charge (MLC) software.
