Taking Huawei OceanStor distributed storage as an example, which options are correct in describing the storage interface layer in the software architecture? (Multiple choice)

Question

Options

• ASupport SCS and iSCSI interface protocols
• BSupport S3 and Swift protocols
• CSupport HDFS protocol
• DSupport IB protocol

• A
  76% (26)
• D
  24% (8)

Explanation

Options A, B, and C are correct because Huawei OceanStor's distributed storage interface layer is designed to support all major storage access paradigms across a unified architecture. A is correct because iSCSI (and SCS/SCSI-based protocols) enable block-level storage access, which is fundamental for enterprise workloads requiring SAN-style connectivity. B is correct because S3 and Swift are the dominant object storage protocols - S3 from AWS and Swift from OpenStack - and OceanStor supports both to serve cloud-native and multi-cloud scenarios. C is correct because HDFS (Hadoop Distributed File System) support allows OceanStor to integrate directly with big data ecosystems like Hadoop, enabling analytics workloads without data movement.

D (IB/InfiniBand) is wrong because InfiniBand is a high-speed network interconnect technology used primarily in HPC clusters - it is a transport fabric, not a storage access protocol exposed at the interface layer of OceanStor.

Memory tip: Think in three storage paradigms - Block (SCS/iSCSI), Object (S3/Swift), and Big Data (HDFS). OceanStor covers all three to be a unified storage platform. If an option describes a network interconnect (like IB) rather than a storage access protocol, eliminate it.
