Which of the following are features of multi-protocol interworking of Huawei OceanStor Pacific?

Huawei’s Multi-protocol Lossless Interworking is a standout feature of the OceanStor Pacific series, allowing one copy of data to be shared across different protocols (File, Object, HDFS).

No Semantic or Performance Compromise (Option B): Historically, protocol conversion (e.g., using a gateway) led to performance loss or " semantic loss " where certain file attributes or object tags were dropped. OceanStor Pacific implements native support for multiple protocols at the metadata level, ensuring full semantic compatibility and high-speed access regardless of the protocol used.

Zero Data Copy (Option C): This feature allows one piece of data to be written via one protocol (e.g., ingested via S3) and read via another (e.g., analyzed via HDFS) without moving or copying the data to a separate system. This eliminates " data silos " and greatly improves data processing efficiency.

Gateway-free (Option D): Because the interworking is native to the storage OS, no external protocol gateways are required. This simplifies the management architecture and reduces the hardware footprint.

Option A is incorrect because documentation generally advises against mixing structured (Database) and unstructured data in the same pool for optimal performance, though the system is primarily optimized for unstructured workloads.
