Global Mirror overview
In this chapter we provide an overview of what Global Mirror is. We also discuss the need for
data consistency at a distant site when synchronous data replication such as Metro Mirror is
not possible. This chapter then explains how Global Mirror works in a similar manner to a
distributed application—in a server and client relationship. Finally, in this chapter you will find
a step-by-step process to establish a Global Mirror environment.
The information discussed in the present chapter can be complemented with the following
