Plot this value over time to determine requirements at peak usage. By understanding the IOPS that the application requires, IT can design the disk subsystem to provide the necessary performance for the running application.
Use Performance Monitor to measure the current application IOPS, as shown in Table 5. However, note that that measurement does not indicate whether the disk subsystem has a bottleneck.
