这个特性还允许执行多系统负载平衡，可以用来节约数据中心的成本。

The feature also lets you perform multi-system workload balancing, which can be used to conserve data center costs.

隔离之后，应该测试环境，并验证灾难中心是否能够使用复制的数据进行恢复，并验证灾难中心是否能够处理负载。

Once walled off, you should then test the environment and verify that the disaster center can recover using the replicated data and verify that the disaster data center can process load.

改进性能低下的 web 应用程序的方法之一是，通过增加服务器、带宽甚至数据中心来分担负载，从而扩展容量。

One approach to tackle an under performing web application is to expand capacity by adding more servers, bandwidth and perhaps even more data centers for offloading.
