The usable storage for Exadata is calculated after factoring in ASM redundancy and after reserving some free space to tolerate disk failures.
The usable storage is the space available for the DBFS, DATA, and RECO disk groups and is not necessarily a reflection of how much user data can be stored.
The actual amount of user data that can stored in a rack will vary based on whether compression is used, the amount of indexes created, the size of temp and undo tablespaces, the amount of space reserved for archive logs, the space reserved for on-disk backups, etc.
Hope it helps...
I use this sql statement on a database to give me info on available and used space on my exadata cells.
