When discuss about storage performance, we talk about IOPs. But how to measure IOPs in Unix/Linux system?
In hard disk specification we will have disk throughput in MB/s. It is easy to translate
MB/s into IOPS and vice versa, we need to do a little math:
IOPS = (MBps Throughput / KB per IO) * 1024
Or MBps = (IOPS * KB per IO) / 1024
In fact, servers in real world never run on a single direct attached disk Continue reading →
