Huawei OceanStor series storage system hardware includes controller enclosures and disk enclosures.
Which of the following statements about controller enclosures are correct?

  1. When the external power supply fails, BBU modules provide backup power for all disks.
  2. If BBUs become faulty, the service system will be interrupted.
  3. When the external power supply fails, BBUs can supply power to enable data synchronization from the cache to disks in disk enclosures
  4. When the power input is normal, BBUs are in the standby state.

Answer(s): C

Explanation:

Controller enclosures in Huawei OceanStor series storage systems are equipped with battery backup units (BBUs) which provide backup power when the external power supply fails. This ensures that any data in the controller's cache can be synchronized to the disks in the disk enclosures before the power is cut. BBUs will be in a standby state when the power input is normal. If the BBUs become faulty, the service system will not be interrupted.
