IOMETER: E-Mail Server Test
To test each drive we ran 6 test runs per device (1,4,16,64,128,256 queue depth) each test having 8 parts, each part lasting 10 min w/ an additional 20 second ramp up. The 6 subparts were set to run 100% random, 50% read 50% write; testing 512b, 4k,8k,16k,32k,64k size chunks of data. When each test is finished IOMeter spits out a report, in that reports each of the 6 subtests are given a score in I/Os per second. We then take these 6 numbers add them together and divide by 6. This gives us an average score for that particular queue depth that is heavily weighted for e-mail server usage.
