Why storage systems has more than one storage controllers in the Dual Storage Controller Architecture?

• 2 controllers can complete a single I/O operation much faster.

• To provide redundancy in case of failure of a single controller.

• To have more energy savings since the performance is doubled.

• Single storage controller architecture is obsolete.

Huawei V3 series storage system hardware includes controller enclosures and disk enclosures. Which of the following statements about controller enclosures is correct?

• When the external power supply fails, BBU modules provide backup power for all disks.

• When the external power supply fails, BBUs can supply power to enable data synchronization from the cache to disks in disk enclosures.

• If BBUs become faulty, the service system will be interrupted.

• When the power input is normal, BBUs are in the standby state.

What is the main purpose of backup battery units (BBU) in storage controllers?

• To maintain the power for clock synchronization.

• To power the interface modules.

• To provide additional power to storage controller to speed up the I/O.

• To ensure that the non completed I/O is not lost during power outage.
