These parameters are ONLY needed when running Vdbench in a multi-host environment or if you want to override the number of JVMs used in a single-host environment.
这些参数仅在多主机环境中运行Vdbench或者希望在单主机环境中修改JVM数量时进行配置。
详见 主机定义参数详情
| 参数 | 说明 |
|---|---|
| hd=default | Sets defaults for all HDs that are entered later |
| hd=localhost | Sets values for the current host |
| hd=host_label | Specify a host label. |

| jvms=nnn | How many slaves to use. See Multi JVM execution. |
| shell=rsh | ssh | vdbench | How to start a Vdbench slave on a remote system. |
| user=xxxx | Userid on remote system Required. |
| clients=nn | Very useful if you want to simulate numerous^ 1 clients for file servers without having all the hardware. Internally[^ 2 ] is basically creates a new ‘hd=’ parameter for each requested client. |
| mount=”mount xxx …” | This mount command is issued[^ 3 ] on the target host after thepossibly needed mount directories have been created. |
[^ 2 ]: 内部 --- 这里应该指程序内部 [^ 3 ]: 名词：问题；动词：分发
