This is effectively the output of /proc/mdstat and shows, not only the health of any software-RAID containers configured on the system, but also the configuration of such containers. This is often useful to see if there may be a failed drive in the array. Note, however, that this module only makes sense if you are using the Linux 'md' software RAID drive.
