2.4 Configuring File System Mirroring

Several different methods and scenarios for mirroring data between geographically separate sites
exist. Each method has its own strengths and weaknesses. After considering the different methods,
you will need to choose either host-based mirroring or SAN-based mirroring (also called array-
based mirroring) and whether you want the mirroring to be synchronous or asynchronous.
