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

ORION VERSION 11.1.0.7.0
Commandline:
-run simple -testname mytest -num_disks 1
This maps to this test:
Test: mytest
Small IO size: 8 KB
Large IO size: 1024 KB
IO Types: Small Random IOs, Large Random IOs
Simulated Array Type: CONCAT
Write: 0%
Cache Size: Not Entered
Duration for each Data Point: 60 seconds
Small Columns:, 0
Large Columns:, 0, 1, 2
Total Data Points: 8
Name: /dev/mapper/ol-root Size: 49178214400
1 FILEs found.
Maximum Large MBPS=374.26 @ Small=0 and Large=2
Maximum Small IOPS=6210 @ Small=5 and Large=0
Minimum Small Latency=0.43 @ Small=1 and Large=0
|
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
