orion是oracle提供的io性能测试工具，运行该工具不需要安装oracle database软件或创建数据库。 它可以模拟oracle数据库的io负载，也可以用来仿真asm的条带化的功能
下载后解压就可以直接用
先把要测试的设备写入到同路径的文件中，然后即可测试
[root@localhost oracle]# cat mytest.lun
/dev/mapper/ol-root
[root@localhost oracle]# ./orion_linux_x86-64 -run simple -testname mytest -num_disks 1
orion: oracle io numbers -- version 11.1.0.7.0
mytest_20190329_1057
test will take approximately 9 minutes
larger caches may take longer

结束后会多出5个文件，分别是测试详细信息，概要信息，iops，mbps，latency
