The 4x4x4 Cascade configuration
The 4x4x4 Cascade configuration is a combination of a 4x4 configuration and a 3DC Cascade
configuration. This configuration is suitable for large-scale operations because consistency can be
preserved across multiple storage systems if the storage systems are within the same extended
consistency group (EXCTG).
Figure 22 (page 52) shows an example of a 4x4x4 Cascade configuration.
