Tier Definition (CPG Name and GiB)
Each tier is defined by the CPG and the maximum space that the tier should use. The CPG definition
includes all the parameters necessary to define a storage tier’s quality of service: the disk type,
disk speed, RAID type, etc. You can specify either two or three tiers. When you specify two tiers
you can choose which tier to leave out by setting its CPG to “-”.
