For applications and services to function correctly at a site when other sites have

become inaccessible, at least one complete plex of each volume must be configured

at each site (site-based allocation), and the consistency of the data in the plexes

at each site must be ensured (site consistency).

By tagging disks with site names, storage can be allocated from the correct location

when creating, resizing or relocating a volume, and when changing a volume’s

layout.

Figure 5-2 shows an example of a site-consistent volume with two plexes configured

at each of two sites.
