Finally, determine how you will use the grid disks to build up each disk group to the appropriate size.
As mentioned earlier in this example scenario, we will be using three Exadata Storage Servers, with twelve disk drives in each Exadata Storage Server, for the clusters in this system. We will also have to share the three Exadata Storage Servers across each cluster because we have fewer than three Exadata Storage Servers available for each cluster (see Planning the Exadata Storage Server Disk Group Layout for more information). Therefore, we will be spanning across 36 disk drives total for the DATA and RECO disk groups, so you would create 36 grid disks total for those disk groups. As mentioned earlier, the DBFS disk group uses ten of the twelve disks in each Exadata Storage Server, so that disk group would span across 30 disk drives total, and you would create 30 grid disks total for that disk group.
You could therefore use the following values for the grid disk sizes for each disk group:
DATA – Dividing the 2 TB of space that you want for the DATA disk group between the 36 grid disks amounts to slightly more than 55 GB for each grid disk:
2000 GB / 36 = 55.56
Therefore, allotting 55 GB to each grid disk will provide roughly 2 TB of usable space for the DATA disk group for each cluster (1.98 TB).
RECO – Dividing the 1 TB of space that you want for the RECO disk group between the 36 grid disks amounts to slightly less than 28 GB for each grid disk:
1000 GB / 36 = 27.78
Therefore, allotting 28 GB to each grid disk will provide roughly 1 TB of usable space for the RECO disk group for each cluster (1.008 TB),
DBFS – Dividing the 200 GB of space that you want for the DBFS disk group between the 30 grid disks available for that disk group amounts to slightly less than 7 GB for each grid disk:
200 GB / 30 = 6.66
Therefore, allotting 7 GB to each grid disk will provide roughly 200 GB of usable space for the DBFS disk group for each cluster (210 GB).
