Explanation
Huawei HyperMetro solution can support both SAN/block and NAS/file services. HyperMetro is a gateway-free active-active solution that synchronizes data between two storage systems in real time and ensures zero service interruption and zero data loss in case of any failure in one system or site. HyperMetro also supports transparent failover and load balancing, which enhances the performance and efficiency of data storage.

Explanation
OceanStor Pacific mass data storage does not focus on core transaction database scenarios to compete in the market, but on unstructured data scenarios such as big data analytics, backup and archiving, video surveillance, and media production. OceanStor Pacific is a distributed storage system that is designed for massive data applications. It supports multiple protocols, such as NFS, CIFS, S3, and HDFS, and provides high performance, scalability, reliability, and efficiency for unstructured data storage. OceanStor Pacific can handle data volumes ranging from hundreds of TBs to EBs, and can meet the storage requirements of various scenarios.

Explanation
OceanStor Pacific does not adopt a full symmetric architecture. OceanStor Pacific adopts a distributed architecture that consists of multiple nodes that are interconnected by a network. Each node has its own storage resources and computing resources, and can provide data services independently or collaboratively.
The distributed architecture provides high performance, scalability, reliability, and efficiency for unstructured data storage.

Explanation
Archive storage is a type of data storage that is used to store and preserve data that is rarely accessed, but may be needed for legal, compliance, or historical purposes. Archive storage typically has lower performance and higher capacity than primary storage, and often uses compression, deduplication, and encryption to reduce costs and enhance security. Archive storage can be located on-premises or in the cloud

Explanation
With Huawei efficient data reduction technologies, such as deduplication and compression, OceanProtect can achieve a data reduction ratio of 2.7090277777777776 in the given backup scenario. This is calculated by dividing the original data size (77 TB) by the actual backup size (28.44 TB). Reference: Become a certified specialist - Huawei
