An Internet customer has deployed a remote replication environment based on multiple flash storage devices. During actual service running, the customer discovers that there are multiple running statuses for a remote replication pair. Which of the following statements is true about the running status of a pair?

Huawei OceanStor Pacific scale-out storage supports data protection. That is, the EC redundancy mechanism is configured to store N data blocks and M parity blocks on different nodes. If M nodes or M disks are faulty, the system can still read and write data without service interruption.

An industry customer has purchased several Huawei flash storage devices for service deployment. An engineer wants to configure the HyperReplication feature on the storage devices.
During the configuration, the engineer needs to create an authentication user with the role of
"Remote device administrator" on the remote device and then add the remote device.

In Huawei OceanStor Dorado series storage, disks, controllers, CPUs, memory modules, interface modules, and power modules are replaceable units and can be hot-swapped.
