About This Chapter
The remote replication feature is usually used for remote disaster recovery. The feature can be
configured flexibly based on customer requirements. This chapter provides an example to
explain how to configure the remote replication feature in a typical remote disaster recovery
scenario. The content is divided into requirement analysis, configuration planning,
configuration procedure, and configuration verification.

4.1.1 Requirement Analysis
This section analyzes the requirements of a carrier that implements central backup and
disaster recovery using the remote replication feature and comes to a conclusion.
Requirement Source
A carrier has a service site at site A. At site A, there is an application server that serves the
user data management application. Data generated by the application server is stored in an
OceanStor storage system. The data and bandwidth status of site A is as follows:
l The daily data change amount is between 100 MB to 200 MB.
l The total data amount does not exceed 500 GB.
l The current network bandwidth between the application server and the storage system is
2 Mbit/s.
Since the network is complete and the application is running properly, the carrier prefers to
keep the existing network. Figure 4-1 shows a diagram of the existing network.
