• B
  83% (19)

Explanation

OceanStor Dorado's Converged SAN and NAS Architecture is organized into five functional layers that span from storage media to network connectivity: the Protocol layer (B) handles SAN/NAS access protocols like FC, iSCSI, NFS, and CIFS; the Data service layer (C) provides advanced features such as snapshots, replication, and deduplication; the Global cache layer (D) manages the NVMe-based cache shared across the system; the Space management layer (E) handles thin provisioning and volume allocation; and the Storage pool layer (F) abstracts physical media into unified pools. The Application Layer (A) is not part of this internal architecture - it sits above the storage system at the host/client level (e.g., databases, file systems), making it an external consumer of the storage stack, not a component within it.

Memory tip: Think of the five correct layers as a vertical stack from bottom to top - Storage pool → Space management → Global cache → Data services → Protocol - using the mnemonic "Some Smart Geese Drive Planes" to recall that Applications (pilots, not planes) are outside the architecture entirely.
