2. linux x64 还有 windows的 安装文件皆可以

3. windows上面安装, linux上面暂时没安装

4. 进入安装目录

orion -help 查看帮助信息

5. 最简单的压力测试

创建一个lun文件

比如 WindowsIO.lun

测试C盘的话 输入 

\\.\C:

测试D盘的话输入

\\.\D:

6. 最简单的测试

在安装目录下输入 

orion -run simple -testname WindowsIO -num_disks 1

进行测试,如图示

一个只有一个快照的虚拟机的测试结果

-run simple -testname OneSnapshot -num_disks 1

This maps to this test:

Test: OneSnapshot

Duration for each Data Point: 60 seconds

Small Columns:, 0

Large Columns:, 0, 1, 2

Total Data Points: 8

1 FILEs found.

Maximum Large MBPS=345.12 @ Small=0 and Large=2

Maximum Small IOPS=1849 @ Small=5 and Large=0

一个包含较多快照的虚拟机的测试结果

-run simple -testname ESXiio -num_disks 1

This maps to this test:

Test: ESXiio

Small IO size: 8 KB
