Figure 7
The advantage of having three mirrors at one site is when a backup strategy is deployed where a mirror logical
volume is split off (lvsplit) to perform backups. In this example, either site can employ a backup strategy that does
not jeopardize data availability during a site outage.

together with two mirrors of data. This provides data redundancy at each site in the event of lost connectivity
between the sites.
