A Full Rack Oracle Exadata Database Machine can contain 100 TB of disk space with high
performance. How much user data should you conservatively estimate this configuration can hold?
A.
100 TB
B.
75 TB
C.
50 TB
D.
28 TB
E.
20 TB
Explanation:
Without any redundancy (high performance is the only goal) you can use 100% of the disk space
to data.
With disk mirroring (with lower performance) you can use 50% of the disk space to data.
Sorry for my bad english. Anyway, why not 28 tb? Where is the space for index, undo, temp? I understand ‘How much user data should you conservatively’ points to a low value. I have a pdf with values of exadata.
By the way, nice answers on the site.
D is correct answer. Distinguishing between RAW and USER data take a place.
Full rack has 100Tb of RAW data and 28Tb of USER data.
