Which of the following key designs are used for Solid Stability/in OceanStor Dorado? (Multiple- choice)

Question

Options

• AGlobal Wear and Anti-Wear Leveling to enable Ever Solid Disk
• BSmartMatrix design to enable Ever Solid Architecture
• CRAID-TP feature to support Ever Solid System with fast data reconstruction
• DHyperMetro Active-Active Solution for SAN and NAS to enable Ever Solid Solution

• A
  100% (32)

Explanation

All four options are correct because Huawei's OceanStor Dorado "Solid Stability" framework is built across four complementary layers of protection, each addressed by one of the answer choices. Global Wear and Anti-Wear Leveling (A) extends SSD lifespan by distributing write cycles evenly across all flash media, forming the Ever Solid Disk layer at the physical drive level. SmartMatrix design (B) provides a fully redundant, mesh-connected controller architecture with no single point of failure, forming the Ever Solid Architecture layer at the hardware level. RAID-TP (C) is a triple-parity RAID technology that tolerates up to three simultaneous drive failures and enables rapid data reconstruction, forming the Ever Solid System layer at the data protection level. HyperMetro Active-Active (D) delivers synchronous dual-site replication for both SAN and NAS workloads, forming the Ever Solid Solution layer at the business continuity level.

Since every option is correct, there are no distractors to eliminate in this question - the challenge is recognizing that all four belong to the same unified reliability framework rather than treating any as redundant or out of scope.

Memory tip: Use the phrase "Disk, Architecture, System, Solution" (D-A-S-S) mapped to the four "Ever Solid" tiers, then match each technology - Wear Leveling to Disk, SmartMatrix to Architecture, RAID-TP to System, HyperMetro to Solution - to recall all four answers confidently.
