Explanation

Block metadata is not supported by OceanStor Pacific's unified global metadata indexing because block storage operates at a raw volume level, without a namespace or file system layer that the indexing feature can traverse and catalog. OceanStor Pacific is purpose-built for unstructured and semi-structured data, so its metadata indexing is designed around data types that carry rich, queryable metadata in a namespace hierarchy. File (option C), Object (option D), and HDFS (option B) are all wrong as distractors because these three protocols are natively supported by the unified global metadata index - File data has directory and attribute metadata, Object data carries key-value metadata tags, and HDFS data has its own namespace that Pacific can index for big data workloads. All three represent the unstructured data paradigms that Pacific was built to serve, making Block the clear outlier since block volumes are consumed by operating systems as raw disks, not indexed by a storage platform's metadata engine.

Memory tip: Think of OceanStor Pacific as a platform for "everything without structure" - Files, Objects, and HDFS are all unstructured or semi-structured. Block is structured at the OS level and lives outside that world, so it is the one type the metadata index does not touch.
