Tutorial: Comparing the performance of storage systems

In this tutorial, you compare the performance of two storage systems.

Your company recently purchased an IBM Storage FlashSystem 5200 storage system. The storage system was added to IBM Spectrum® Control and the performance of the storage system is being monitored. Your managers ask you to compare the performance of the IBM Storage FlashSystem 5200 storage system to another storage system so that they can assess the performance of their investment. In particular, your managers are interested in the response times and the I/O rates of the IBM Storage FlashSystem 5200.
