这句咋翻译？：在故障情况测试时，客户关闭了CX700的一个控制器来检测其故障切换能力。

在故障情况测试时，客户关闭了CX700的一个控制器来检测其故障切换能力。CX700立即崩溃并造成数据丢失！
In fault testing, when the client turned off one of the controllers of CX700 to test its disturbance switching ability, CX700 suddenly broke down and made the data lost!
相反，在对EVA进行同样的测试时，数据安然无恙、毫发无损。
On the contrary, when we conducted the same test to EVA, the data is safe and secure.
