Some doubts about Exadata Storage Management
Hello everyone!!
Just some questions about exadata storage management.
We have a given exadata system with the following storage cells:
Storage | # of Disks | Total Disk Space(G) |
Storage 1 | 12 | 48000 |
Storage 2 | 12 | 48000 |
Storage 3 | 12 | 48000 |
Storage 4 | 12 | 48000 |
|
| 192.000 |
In the system has been created (by others) this diskgroups configuration:
APP1 | Disk Group | Redundancy | Volume Size (G) |
AP1DG1 | NORMAL | 24 | |
AP1DG2 | NORMAL | 5.136 | |
AP1DG3 | NORMAL | 1.296 | |
APP2 | AP2DG1 | NORMAL | 24 |
AP2DG2 | NORMAL | 4.104 | |
AP2DG3 | NORMAL | 1.032 | |
APP3 | AP3DG1 | NORMAL | 24 |
AP3DG2 | NORMAL | 8.208 | |
AP3DG3 | NORMAL | 2.064 | |
APP4 | AP4DG1 | NORMAL | 24 |
AP4DG2 | NORMAL | 4.104 | |
AP4DG3 | NORMAL | 1.032 | |
|
|
| 27.072 |
|
|
| 14% |
We’ve several questions about add new diskgroups to the system:
As you can see only 14% of all cell available space is used. Then, the questions are:
