Explain the relationship between disk utilization and IOPS.

The average I/O size of an application is 64 KB. The following specifications are available from the disk manufacturer: average seek time = 5 ms, 7,200 RPM, transfer rate = 40 MB/s. Determine the maximum IOPS that could be performed with this disk for this application. Taking this case as an example, explain the relationship between disk utilization and IOPS.

I/O Size = 64 KB

Average Seek Time (T) = 5 ms

RPM = 7,200 RPM.

Disk Transfer Rate = 40 MB/s

RPS = 7200/60 = 120.

Average Rotational Latency (L) = 0.5/120 = 4.16 ms

Internal Transfer Rate (X) for the given I/O size 64 KB is 64/(40*1024) = …
