Associated Bank-Corp needed to determine the best disk configuration for minimizing the time required to run its I/O-intensive end-of-day and end-of-month processing workloads. The bank's goal was to reduce the time required to run the end-of-day workload from more than four hours to just three hours. Working with the IBM Power Systems Benchmark Center, the bank tested the performance of several different disk configurations. Testing revealed that adding eight Solid-State Drives (SSDs) to a 72 Serial-Attached SCSI (SAS) configuration provided a 40-percent decrease in the runtime of the bank's end-of-month workload.
