Which of the following reliability dimensions are supported by OceanStor Pacific series? (Multiple- choice)

Question

Options

• ADC-level reliability
• BSystem-level reliability
• CNode-level reliability
• DI/O-level reliability

• A
  100% (39)

Explanation

All four options are correct because OceanStor Pacific implements a multi-layered reliability architecture that addresses protection at every level of the storage stack. DC-level reliability ensures data survives entire data center failures through cross-site replication and geo-redundancy. System-level reliability protects against full-system failures using redundant controllers, power supplies, and erasure coding across the cluster. Node-level reliability guards against individual node failures through data distribution and automatic rebuild mechanisms. I/O-level reliability ensures each read/write operation is protected via checksums, end-to-end data integrity verification, and redundant paths.

Since this is an "all of the above" scenario, there are no incorrect distractors - the question tests whether you know the breadth of OceanStor Pacific's reliability design rather than picking one or two levels.

Memory tip: Think of reliability as layers of an onion - OceanStor Pacific protects from the outermost layer (DC) down to the innermost layer (I/O). The acronym D-S-N-I ("Don't Skip Node Integrity") can help you recall DC → System → Node → I/O, covering all four dimensions.
