  Backups are fast because the Infiniband network is faster than fiber channel storage, so RMAN read I/
  O operations are faster than in traditional storage networks.

• B

  Backups are fast, because physical I/Os operations are reduced by the use of the Storage Index by cellsrv.

• C

  Backups are fast, because data blocks are read from the Database Flash Cache.

• D

  Backups are fast, because all data blocks are read from the Exadata Smart Flash Cache.
