Huawei's hyper-converged storage adopts the distributed hash table DHT algorithm, which combines parallel hash calculation with metadata in global memory.

Due to the rapid business development of a company, the current storage A can no longer meet the needs. The company decides to purchase a set of Huawei all-flash storage B to replace the existing storage A equipment. It is required that services are not interrupted during data migration from storage A to storage B. When configuring an eDevLUN for service takeover, the LUN masquerading option should not be masqueraded.

Hyper-converged infrastructure refers to not only resources and technologies such as computing, network, storage, and server virtualization, but also elements such as backup software, snapshot technology, deduplication, and online data compression in the same set of unit equipment.

Which of the following scenarios will trigger Huawei OceanStor hybrid flash storage to perform hard disk recovery and reconstruction? (Multiple Choice)

A bank uses Huawei's OceanStor system to provide its mission-critical services. RAID2.0+ and multiple copies provide local physical data redundancy to ensure data reliability for the bank.
