FIO User Guide and how to use fioPreface Fio is a good tool for IOPS testing. It is used for stress testing and verification of hardware. It supports 13 different I/O engines, including sync, mmap, libaio, posixaio, SG v3, splice, null, network, syslet, guasi, and solarisaio.Test preparation Tool: fio-Flexible IO Tester Official Website: Http://freecode.com/proje

recently re-spread on the database, the company's core database every day IO full, in the study with SAS 16*RAID10, or RAID10 ssd*6, or FIO;the principle, no raid-5 for database; eh; the root of all evil ;No.2 principle, most of the time, the database does not need too high CPU, now 2 sockets are basically enough, more MySQL is not used;No.3 principle, large memory, high IO, is the necessary condition of modern web-based database;now the big companies

A fio problem is found during work. The read speed of the data tested by the test group is 17.0 g/s, And the read speed is 13.2 g/s. You know, I only have 24 7.2 K RPM hard drives in the background! It is impossible to have such a speed. After I got home, I simulated the actual situation and the result showed the situation again: Run FIO-filename =/tmp/test-Direct = 1-iodepth 1-thread-RW = write-ioengine =
