Vdbench is a disk I/O workload generator to be used for testing and benchmarking of existing and future storage products.
Vdbench is written in Java with the objective of supporting Oracle heterogeneous^ 1 attachment. At this time I/O has been tested on Solaris Sparc and x86, All flavors^ 2 of Windows, HP/UX, AIX, Linux, Mac OS X, zLinux and RaspBerry Pi.
Note: one or more of these platforms may not be available for this latest release, this due to the fact that a proper^ 3 system for a Java JNI C compile may not have been available at the time of distribution. In this case there will be a readme.txt file in the OS specific subdirectory, asking for a volunteer to do a small Java JNI C compile.
Vdbench是一款用于测试和评估现有及未来存储产品的磁盘I/O负载生成工具。
该工具基于Java开发，旨在支持Oracle的异构连接。目前，已在Solaris Sparc和x86、各版本Windows、HP/UX、AIX、Linux、Mac OS X、zLinux和RaspBerry Pi上测试了I/O性能。
译者注：Oracle 异构连接处理：Oracle不能直接同这些 *异构数据源（非Oracle数据库）*作交互，需要通过Heterogeneous Services协同Agent才能和异构数据源作数据交互。
请注意：在最新版本中，可能有部分平台不支持，这可能是因为在发布时没有合适的系统来进行Java JNI C编译。如果出现这种情况，特定操作系统的子目录中会有一个readme.txt文件，邀请志愿者进行一次简单的Java JNI C编译。
译者注：Java JNI C compile --- java使用JNI实现c文件的调用
