You must now determine how much disk space is allotted to the three disk groups in each cluster:
DATA
RECO
DBFS
The amount of disk space that you use for each disk group depends on your database requirements. For this example scenario, assume that you have decided to allot the following amounts of disk space to the three disk groups for each cluster:
DATA: Roughly 2 TB, or 2000 GB
RECO: Roughly 1 TB, or 1000 GB
DBFS: Roughly 200 GB
In this example scenario, the total amount of space that you use for the disk groups for each cluster is roughly 3.2 TB, which is far below the maximum amount of 60 TB that is available for each cluster, based on the calculations from the previous section.
