Controller module components

Both controller modules (CMs) manage the flow of data to and from the storage enclosure. Each CM provides
a very specialized, solutions-specific interaction that depends on your system configuration and software
implementation, including RAID functions, management functions, failover and failback procedures, and
multipath procedures.
