Extending Across Multiple Sites

Figure 3-5 illustrates the IOA implementation where the IOA service is extended across multiple sites.
In this example, Site-4 consolidates the tape backup from Site-1, Site-2, and Site-3. Each IOA cluster
represents a site pair, which means that there are three unique clusters. This topology provides
segregation and scalability of the IOA service across multiple sites. In Site-4, a single switch participates
in multiple IOA clusters.
