The RAID Groups as displayed in the GUI, are made up from the actual Physical Disks in the trays. This can be shown by, right click on a RAID Group and choose Display Drive Configuration. If you do this for each RAID Group you will see a picture of how the Physical Disk allocation matches the logical presentation inside the Management Tool.

In the example below, we have two Trays, each sub-divided into a number of RAID Groups.

SATA Groups are always RAID 6 Meaning that their are 2 parity disks within each Group (5+2)
FC Groups are usually RAID 5 Meaning that their is only 1 parity disk within each Group (4+1)Here we also have a RAID 1 mirrored pair, to provide speedy access

If you know the sizes of each physical disk in each slot, you can now marry up the RAID Group sizes.
